Substitution Ciphers in Python | PTP #1

PTP #1
As I continue my coding journey I decided to look into ciphers. The purpose of this project was to implement four substitution ciphers in (p)ython (a)nd lea(r)n a little m(o)re about the math behind them. I’m (s)ure every(o)ne has heard of the Caesar cipher, (m)yself i(n)cluded, but after looking that up I fell (i)nto (a) rabbit hole of a few other types of substitution (c)iphers I wanted to learn about as well. Comment below with your favorite cipher or any suggestions for improvement!

Note: In the video I didn't account for the key in the viginere cipher having uppercase letters. I have since updated the code to return the key as lowercase with return key.lower()
