Now in Python 3, however, this doesn’t work (I assume because of the bytes/string vs. string/unicode switch. ROT13 is an example of the Caesar cipher. Cryptography with Python – ROT13 Algorithm. A Quine is a program that, when run, prints its own source code (without resorting to easy solutions like reading its code from the filesystem). Luckily Python is a not too hard programming language to start with. The user can choose a number to rotate each alphabetical character by that number, and the output box will diplay the converted text. Your program should have I/O and that's how it's supposed to look (if possible):. Python 3 - String decode() Method. Numeric and non-alphabetical characters remains untouched. Tip: Encoding and decoding are done by the same function. It is a cipher algorithm that can deter unwanted examination. In other words, I am not sure if Berker's test is currently a supported usage. young children) to read unintentionally; that is one has to intentionally "decode" the encoded text to make sense of it.
