How do i add two lists' elements into one list?

Question

For example, I have a list like this:

list1 = [good, bad, tall, big]

list2 = [boy, girl, guy, man]

and I want to make a list like this:

Answer 1

Using zip

list3 = []
for l1,l2 in zip(list1,list2):
    list3.append(l1+l2)

list3 = ['goodboy', 'badgirl', 'tallguy', 'bigman']

Answer 2

for this or any two list of same size you may also use like this:

for i in range(len(list1)):
    list3[i]=list1[i]+list2[i]

Answer 3

You can use list comprehensions with zip:

list3 = [a + b for a, b in zip(list1, list2)]

zip produces a list of tuples by combining elements from iterables you give it. So in your case, it will return pairs of elements from list1 and list2, up to whichever is exhausted first.

Answer 4

A solution using a loop that you try is one way, this is more beginner friendly than Xions solution.

list3 = []
for index, item in enumerate(list1):
    list3.append(list1[index] + list2[index])

This will also work for a shorter solution. Using map() and lambda, I prefer this over zip, but thats up to everyone

list3 = map(lambda x, y: str(x) + str(y), list1, list2);
