Python mirrored string function

Question

I\'m trying to develop a function mirror() that takes a string and returns its mirrored string but only if the mirrored string can be represented using \"mirror

Answer 1

Firstly, you should have a dictionary that stores the mirror image of every character.

mirrored = {'b': 'd', 'd': 'b', 'v': 'v', ...}

So, for every string that we need to produce a mirror of, you should check that every character in the given string has it's mirrored value in the string itself.

given_string = input()
valid = True
for char in given_string:
    if not mirrored[char] in given_string:
        valid = False
        break
if valid:
    # generate mirrored string

The reversed string approach you are using is right. Just add above check & you'll be on your way to generate mirrored strings!

Another way to do this, would be using a simple Python hack of for...else

given_string = input()
valid = True
for char in given_string:
    if not mirrored[char] in given_string:
        break
else:
    # generate mirrored string
