Question

Learning Python here: I am simply trying to switch characters in a string. Example: ‘A’ to ‘C’. The string just isn’t doing anything. Here is what I have so far:

import string
dummy = "beans"
for i in xrange(len(dummy)):
    chr(ord(dummy[i])+5)
print(dummy)

Answer 1

Remember that strings are immutable, so you will need to re-assign your original string. You can try something along these lines:

dummy = "beans"
newdummy = ""
for i in xrange(len(dummy)):
    newdummy += chr(ord(dummy[i])+5)
dummy = newdummy
print(dummy)

This would be a more Pythonic approach:

dummy = ''.join(chr(ord(c) + 5) for c in dummy)
print(dummy)
