=python join arrays code example

Example 1: join lists python

first_list = ["1", "2"]

# Multiple ways to do this:
first_list += second_list
first_list = first_list + second_list
first_list.extend(second_list)

Example 2: how to combine two lists in python

l2 = [1, 2, 3]
l1 + l2
>>> ['a', 'b', 'c', 1, 2, 3]
