Adding numbers in front of printed list items in Python

Question

So I have a list like:

    L = ['a', 'b', 'c', 'd']

and

    for x in L:
        print(x)

returns

    'a'
    'b'
    'c'
    'd'

but I would like to see

    1. 'a'
    2. 'b'
    3. 'c'
    4. 'd'

I would like to have this work for any size the list might grow or shrink to. I have tried a few things but I am very new to programming and nothing has worked.

Use enumerate

for i, x in enumerate(L):
    print('{0}. {1}'.format(i, repr(x)))

Using repr will not give the same result. print uses str

I'm not sure what you mean. I used repr because otherwise it won't include the quotes.

I see. I'm not sure if that's what he wants, however, because his original would not include the quotation marks. I could go either way on that.

Thank you Brendan. And thank you zondo, I just changed repr to str

Brendan, I looked on python.org at enumerate because I wanted to learn more. But it didn't answer a question I have about the way you printed it. in the beginning the {0}. {1} what exactly does that do?
