Changing python immutable type while iterating through mutable container like list

Question

I am wondering what is the most pythonic way to do the following and make it work:

strings = ['a','b']

for s in strings:  
    s = s+'c'

obviously this doesn't work in python, but the result I want to achieve is Strings = ['ac', 'bc']
What is the most pythonic way to achieve such a result?

Thanks for the great answers!

Answer 1

strings = ['a', 'b']
strings = [s + 'c' for s in strings]

Answer 2

You can use the list to create a list that has the following values: [s + 'c' for s in strings]. You can change the list in place as follows:

for i, s in enumerate(strings):
    strings[i] = s + 'c'

Answer 3

.

strings = ['a', 'b']
strings = map(lambda s: s + 'c', strings)
