This is a great way to show your friends, family, creditors and enemies what a cool website you've put together.
So... Fill out this form
This is "opt-in", which means that:
0. If you don't decide, or you decide "no" then your name will not appear
1. If you fill out the form with "yes", then it will appear.
2. Individuals in partnerships can make individual decisions.
Thurs. 10:30a - 12:30p
Thurs. 4:00p - 6:00p
Thurs. 10:15p - midnight
Mon (6/15): noon - 2:00
Write me email when you'll be arriving...

No late penalty until Mon. morning 8:00am
due Wed night (6/10).
If you don't need that "extra boost", you do not need to move your homepage.
If you feel that you do but are unable to reconstruct your homepage on Moe, we'll need to figure out if and how to provide that "extra boost".
So... to move:
Copy all of your homepage files from your computer (remember, Marge, Lisa and Homer are down) up to your public_html directory (or a subdirectory of public_html that you create) on Moe. Test (test) (also test) your personal homepage and then put the URL onto the homework server slot that says: "Personal homepage on Moe". DO NOT PUT IT IN THE FINAL PROJECT SLOT!
1. The project must correspond, as closely as possible, to the proposal that I accepted on the homework server.
2. It must be thoroughly tested so that any bugs DO NOT CRASH it. If there are problems with what the user enters or selects, provide guidance to the user to get back on track.
3. The project must have an ABOUT page, with a prominently visible link to it on the primary page of the project (link either on top or bottom of the primary page).
4. Remember: if the Python program used by your website on moe has to write data to any files, those files must be located on your public_html/www directory.
5. Put the link to your primary page into the Comments-to-Teacher.
The ABOUT page should contain:
a) The name of the project
b) The author(s)
c) The intent of the project, and any instructions that are not elsewhere on how to use it successfully (with possible examples of its usage).
d) Any differences between what the project does and what the proposal said it would do (it would be best if I didn't find those differences myself)
e) Any bugs or problems that you are aware of that the user should avoid triggering (again, it would be best,...etc.)
f) Sources of information, sources of code, sources of data used.
g) Any interesting insights or experiences you've had in going through the creation journey.
h) Acknowledgements of those who helped.
How to get: show_cookies.txt
Demo (V.2) http://moe.stuy.edu/~pbrooks/www/cookies_demo.py
Here's a demo of it.
Here's the Python program.
Here's the first HTML page (input_hidden_1)
0. solo or duo? If duo, who is your partner? Also if duo, both of you MUST submit project proposals (probably identical)
1. a quick description of the website you're planning.
2. Why will the user return (possibly repeatedly) to your site? What value will the site have for the user?
3. If you're processing information obtained from elsewhere on the net, where is it coming from? Have you obtained it and looked at it to make sure that you'll be able to write a Python program to access the data that you'll deliver to your users?
Due, Wed. 5/27 midnight.
Here's the homework: 2 histograms and one bar chart. There's been a fix to the data file used by this homework.
We'll install it in Thonny on Windows, if it's not already installed, using Thonny's "Tools/Manage packages" menu item.
For Mac folks, if it's not already there, download the following version of Thonny:
https://github.com/thonny/thonny/releases/download/v3.2.7/thonny-xxl-3.2.7.pkg
Here's a video from Mr. Dyrland-Weaver on installing Matplotlib on Thonny.
Here's the tutorial you should go through for learning to use the pyplot object of matplotlib
Note: Whatever the user fills in or does not, your program must not crash. If there's a problem, give the user a decent error message.
| letter-form.html looks like this: |  |
| The webpage response should something look like this (the date need not be accurate): | Monday, 3rd month, 12 B.C.E. Dear Ms. Canaanite-Smith It is with great pleasure that we have decided to send you this kangaroo as a small token of our esteem. Unfortunately, returns are currently not possible. Sincerely, The Management |

Then, let's use the data in the big SAT.csv file to report on a random school. Here's the main homework.
between Webservers and Python programs
#! /usr/bin/python
print('Content-type: text/html\n')
print('<html><body>Python runs!</body></html>')
Having stored this into the file fred.py, now change its file permissions to executable using the command:
chmod +x fred.py
...and then you can test it by going back to your browser, opening a new tab and typing: moe.stuy.edu/~your-account/first.py
find(s,c) returns the position of the first occurrence of the character in argument c inside the string s, or -1 if c is not found
reverse(L) reverses the order of the elements in the list L
Here are some interesting solutions from students that we covered today...
Due: Wed. 5/6 midnight
Due, Fri, 5/1 midnight.
Due Tues, midnight.
We're looking for data that can be downloaded, can be processed by a Python program, is free (not behind a paywall), and is interesting. That amounts to pure textual files, or CSV or TSV files.
Report your data catch here: https://forms.gle/pSwLeUC7m4MW4MDC6
Your submissions have been reformatted into a web page, sorted by URL: DataSourcesWeb.html
Once more, here's the Table of Contents of the mini-tutorials:
TOC
Best preparation: Read the mni-tutorials on Split and Join (see the TOC to the left) and the one on working with CSV files and Sorting.
Also, look at the following file SAT-2010-small.csv. It's a csv file, but some lines don't follow the expected "rules" and will crash your Python program if you're not aware of the problems. Find the problems (there are at least two different types of problems in this file). Look at the file with an ordinary text editor and also with a spreadsheet. We'll talk about this on Thurs.
Homework, due Tues, night.
On the following topics:
File reading and Writing and Try/Except
Reading/Using CSV files
Assignment: Create a function MaxSalary(filename), that will read files just like the sample.csv file mentioned in the Reading/Using CSV files section, and returns a list containing the name of the person who has the highest salary, and the salary itself. Example:
print(MaxSalary('sample.csv')) # -> ['Voldy', 28.1]
Here's the file you'll use: salaries.csv
Put the answer into the Comments-to-Teacher, and upload the file to the homework slot .
We'll still be using Zoom for a day or two, until transition to Google Meet or Microsoft Teams.

Hi, I've attached links to both the main page and puzzle packet for the 2020 CS50x Puzzle Day challenge.
No prior CS experience is necessary for the competition, though I'd argue some problems can be solved
via a well-designed program and some are easier to crack if you have computer science vocabulary knowledge.
Anyway, these problems are fun and help build logical thinking skills used in cryptography and programming.
Thanks,
Daniel Lyalin

Please read the Instructions found by pressing "Why a new version?" on the main schedule page.
Put all of the functions that you've created into a single .py file, and upload that to the homework server. While doing that, also put the answer to the optional Double Challenge problem into the Comments-to-Teacher.
Dojo will now be available online through slack. Please share this link (https://join.slack.com/t/
Do problems in the group: Character Manipulation
Today, we start on encryption.
A list of string methods can be found here.
Here are some string functions, a keyword and methods.
Do the first 4 exercises in Mr. K's "Character Manipulation" set.
Meeting ID/Pwd will be sent to you by email (keep that data).
The next set of exercises are Mr K's group: "String and Loops". Do not use the built-capabilities and functions: ".find", ".count", or the "in" operator -- I realize that removes shortcuts, but I'm getting you to do things with loops. Later, we'll use these methods and functions.
0) Choose a topic/event/accomplishment of newsworthy importance that has to do with the digital world that interests/intrigues you.
1) Write a paragraph or two explaining why it's interesting, and post it on the Intro QAF.
2) Report on it during a 5-minute DD session at the beginning of the period on the day assigned to you (each person will know in advance). There will be time for questions afterwards.
I've posted a sample DD in the QAF.
The Presentation Schedule
Period 4: Meeting ID: 164-555-967
Periods 8-10: Meeting ID: 148-166-363
Meeting ID: 968-834-592
Period 4: 10:00
Meeting ID: 940-161-203
Period 8: 12:50pm
Period 9: 1:30pm
Period 10: 2:10pm
Do the exercises in the String-2 and List-2 sets mostly with for and a few with while. Note: the particular exercise: sum67 in List-2 is requires more thinking than usual.
What we covered: Splitting a non-negative integer into its ones digit and the rest. Given an integer n=157, we can do the splitting in two different ways: using arithmetic or using strings:
A) ones digit: n % 10 → 7 and the rest: n // 10 → 15
B)turn the number into a string using the str() function:
s = str(n) and ones digit is s[-1] → '7' and the rest is s[:-1] → '15'
We are going to do the numeric exercises in Mr. Konstantinovich's version of CodingBat: https://codingbat.com/home/konstans@stuy.edu/all
Starting on the exerecise groups: "Looping Numbers" and "Looping over Digits"
Meeting ID: 805-292-466
Period 4: 10:20am
Office hours today: 12:00 - 1:00
Meeting ID: 512-797-337
Period 8: 1:25 pm
Period 9: 2:10pm
Period 10: 3:00pm
(no more 6:00 Catchall sessions...)
Do by today: Warmup-2 with while in CodingBat (even though you may have a shorter way of writing the code for some of these exercises).
Looping docs, new, improved -- now with for and other nutrients (range)
Thonny: I mentioned that I was looking at a competitor to IDLE, called Thonny. Yes. Go to the Thonny site, read about its capabilities, then download and install (see installation instructions below), and try it. We'll be using Thonny for a while -- it's easier to show and test code in this split-screen environment. There's a quick tutorial video on that Thonny main webage.
Thonny installation instructions:
- The simplest is to go to the Thonny site: https://thonny.org/ and see at the top of the page the download links for Windows and Mac (and instruction for Linux)
- If you're having some trouble, here's a video on installing it.
CodingBat: Finish sections String-1 and List-1 by today. We are going on to looping. Assignment (=), decisions (if) and looping (while, for) are the basic dynamic operations in Python.
Looping docs (while)
Period 4: 10:20am
Period 8: 1:25 pm
Period 9: 2:10pm
Period 10: 3:00pm
Could not make it to my to my regular time, session: 6:00pm
We'll be going over lists, so look at the handout below, and do the exercises, and have questions prepared. We'll also be looking at some more advanced list capabilities (list methods).
I showed a great website listing the most popular list and string methods (for Python 2.7). Here it is: http://rgruet.free.fr/PQR27/PQR2.7.html. Go to that page, and find the word "string" or :list" in the first section "Contents", and click on it.
Regular CodingBat porblems: "List-1". Remember to log in.
...moving into a new realm...
We're going to try out ZOOM!
You should all have
received email from me about 2 sessions on Tues, with instructions
and meeting IDs and passwords to try out this free online video
conferencing software. If you're going to be using your
smartphone instead of a computer/tablet, download the Zoom app
ahead of time.
We'll be getting together separately,
according to Periods this time (but possibly all together on other
days).
- Period 4: 12:20pm
- Period 8: 12:40pm
- Period 9: 1:00pm
- Period 10: 1:20pm
If you cannot make your period's meeting time, there will be a 6:00pm session as well for anyone who couldn't make it previously.
Afterwards, fill out the survey form (even if
you couldn't make a session):
https://docs.google.com/forms/d/e/1FAIpQLSen_IB6LqX1gY5pLzw3QGW2fh1AXbzeXG7kQMyR1WFM4CAvCw/viewform?usp=sf_link
Schools closed until April 20.
More later...
- Here's the regular CodingBat (https://codingbat.com/) site that we'll be using today and until Sat night (not the version that Mr. Konstantinovich created).
- Go to this site.
- Log in
- Switch to the Python problems.
- Do the problems in sections STRING-1, LOGIC-1 and LOGIC-2
- I will be able to see which problems you've solved
Votes due on the homework server by Sat. 3/14 midnight
- View ALL of the pages for the students in your class (not just the ones in your competition).
- Vote only for students in your class.
- Post, in the homework slot, your vote for the 1st and 2nd best, by name of student.
- Do not vote for yourself -- will not be counted.
- No vote-buying, no threatening, NO COLLUSION!
- Remember your Construction-Details page citing all the help, code, moral support you received, the problems you overcame, the new skills you acquired.
- You'll need to upload your homepage(s) to your public_html directory.
- then test your URL that you will publish to the outside world. For instance, if your login id is "fred" and your homepage is "harry.html" then the URL will be http://homer.stuy.edu/~fred/harry.html. Make sure you TEST YOUR LINK
- Into the homework slot's Comments-to-Teacher, copy your URL and say whether you want to enter the class competition or not. If you forget to specify this, I'll assume that you want to compete.
If the tool that you've chosen to use is not on your own laptop (it's a web-based editor, running in your browser), then make sure that you can download the resultant HTML file that you creat, and that you can incorporate a picture that your have on your laptop into the document.
CSS controls the visual style of the content of a page, although older HTML tags still do some (like <b> and <i>).
Javascript is a full-fledged language, like Python, Java and Netlogo. It is used to control anything dynamic on the page (anything that moves or responds).
b) Upload the html file to your public_html directory.
c) Create and test a URL that allows anyone knowing it to see your page over the internet
d) type that URL into the Comments-to-Teacher in the homework slot for this assignment

Try using the "ls" command with directory arguments
For instance: After logging in, you'll be in your home
directory. Try:
ls bashcrawl
ls
ls bashcrawl/..
ls /
You
can specify any directory address with ls. And also with ls -F
as in
ls -F bashcrawl
Also, take a look at:
ls -l
ls -al
Get thee into a Terminal window (fast way: Ctrl-Alt t)
Read all of the instructions below before executing any of the commands (in red)...
Execute the following 3 commands exactly (note where the spaces and punctuation are)
scp -r 149.89.17.19:/stuyinstall/bashcrawl ./
After you execute that command, you'll be asked for your password. While you type your password, you won't see the letters you type ... that's all right, just finish and hit the Enter key. Lots of output will be sprayed at you. That's all right too.
cd bashcrawl/entrance
cat scroll
In this game, you'll be entering rooms (actually directories) using the "cd" command, and then looking at the contents of a room (the files in the directory) using the "ls" command, and then perhaps, displaying the contents of files (partcularly the "scroll" file) using the "cat" command.
If you want/have to start over, type the "cd" command without arguments, and then continue with the red command above ("cd bashcrawl/entrance").
