If the new position of the letter doesn’t go beyond the position of the last letter (alphabet[-1]), then you return the letter at this new position. To do that, you use the built-in function chr(). chr() is the inverse of ord(). It takes an integer representing the Unicode cod...

ASetis a set of characters enclosed in ‘[]’ brackets. Sets are used to match a single character in the set of characters specified between brackets. Below is the list of Sets: Match Object A Match object contains all the information about the search and the result and if there is no ...
This algorithm allows for basic text encryption by shifting the alphabet by a number of letters. For example, if you shift the letter a by three, then you get the letter d, and so on.The following code implements cipher(), a function that takes a character and rotates it by three:...
the entire alphabet is written out in reverse starting at that letter. This attack can be accelerated using a set of strips prepared with the alphabet written down in reverse order. The strips are then aligned to form the ciphertext along one row, and the plaintext should appear in one of...
