Chain

Adjoining iterables into one iterable object

The chain module is imported from the itertools library.

from itertools import chain
# Two lists (iterable objects)
fruit = ['apple ', 'banana ', 'strawberry ']
amount = ['1' ,'2' , '3']

Combining them into a single list with the following

combo = list(chain(fruit, amount))
print(combo)

combo will attach the lists in the order received in the command. The order of the content of each list will not be altered.

['apple ', 'banana ', 'strawberry ', '1', '2', '3']

In the above example, a new list was created but replacing the keyword list with set or tuple will give the corresponding object type.
