appending to the strings within a list of strings in python

Question

so i saw this as an answer to a question from a year ago about adding/extending a string, etc.

s  = 'foo'
s += 'bar'
s += 'baz'

l = []
l.append('foo')
l.append('bar')
l.append('baz')

my question is how would one combine these two features? l would return:

['foo','bar','baz']

but what if i wanted to add a letter to the end of each string in the list and then have it return:

['food','bars','bazy']

is this a thing or is it more wishful thinking?

If you want to add a different character to the end of the elements of the array, then you will have to iterate over each of them, and modify them in-place. — NedStarkOfWinterfell

I'm not sure I understand. Are you looking for something like this:

first_list = ['foo','bar','baz']
second_list = [x+y for x,y in zip(first_list,'dsy')]

you can use zip() along with join() and map().

In [72]: lis=['foo','bar','baz']

In [73]: map("".join,zip(lis,'dsy')) 
Out[73]: ['food', 'bars', 'bazy']
