How do I make a list concatenating the corresponding elements of two lists of strings in Python?

I want to make a new list concatenating the corresponding elements of lists of equal-sized strings. For instance, for

list1 = ["a","b","c"]
list2 = ["d","e","f"]

, the output should be

["ad", "be", "cf"]

you can also use join instead of +

print [''.join(x) for x in zip(listone, listtwo)]

You can use list comprehension and the zip() method- 

print [m + n for m, n in zip(listone, listtwo)]

Use map:

>>> from operator import add
>>> one = ["a", "b", "c"]
>>> two = ["d", "e", "f"]
>>> map(add, one, two)
['ad', 'be', 'cf']

Firstly, your chars should be in single/double quotes:

listone = ['a', 'b', 'c']
listtwo = ['d', 'e', 'f']

Then you can do: 

listthree = [i+j for i,j in zip(listone,listtwo)]

>>> print listthree
['ad', 'be', 'cf']
