def Work(str):
    for i in range(len(str)):
        return i * 2

But it does not work . how can I do this?

Answer:

The main reason your code is not working may be your return function. If you want to repeat char in string please use this code:

def Work(str):
    allin = ''
    for character in str:
        allin = allin + char + char 
    return allin

If you dont want to use loops you can use:

def Work(str):
    return ''.join([c+c for c in str])

I hope this may help you the most. If you still do not understand please fell free to ask me anything you want to know about this thing.

Happy Coding.
