Python Homework #10

Instructions:

Remember:

You can compare letters like so: "A" >= letter

Use chr and ord to write the following functions:

Write a function shiftOne(someText). someText is a string consisting of only uppercase characters. The function should return the same text, but with each character shifted up by one in the alphabet, wrapping around after Z.
```
# shiftOne("HAL") -> "IBM"
# shiftOne("BZDRZQ") -> "CAESAR"
```

Write a function shiftN(someText, n). someText is a string consisting of only uppercase character, n is an integer. The function should return the same text, but with each character shifted up n positions in the alphabet, wrapping around after "Z"
```
# shiftN("ABC", 25) -> "ZAB"
# shiftN("ABC", 26) -> "ABC"
# shiftN("KZNEXFGURFCBG", 13) -> "XMARKSTHESPOT"
```
