basic random number generator in replace function

[deanhystad]

Is an example needed? The question is, "Can I use random with replace()?" I take this to mean if we are doing string.replace(old, new) and there are multiple occurrences of "old" in "string", can he somehow use "random" to make a new "new" for each occurrence. I don't see how that can be done.

This obviously doesn't work:

import random
 
a = 'Now is the time for all good men to come to the aid of their country'
b = a.replace('t', random.choice(('A', 'B', 'C')))
print(b)

random.choice gets evaluated and the result is used for "new" in all the replacements.

Output:
Now is Ahe Aime for all good men Ao come Ao Ahe aid of Aheir counAry

I cannot think of a way that you can re-evaluate "new" for each replacement. I think you need to look for another solution to this particular problem.
