Bitwise Xor Python

I am trying to solve a problem where I have to decrypt a file. But I found an obstacle. As you can see in the below code, I need to do a bitwise xor between key and number 47. fro

Solution 1:

because you need an int

ascii_code_for_a = ord('a') == 97#convert a character to an ascii integerint2chr = chr(97) == 'a'#convert an ascii code back to a character

so just do

key = list(iv) # first convert it to a list ... strings are unmutablefor i inrange(len(key)):
    key[i] = chr(ord(key[i]) ^ 47)
