Tuples

Tuples are identical to lists, except that they are immutable (they can't be changed).

Tuples are created with parentheses ():

my_tuple = (1, 2, 3)

my_tuple[1] = 4 # Won't work

Contrast this with lists:

my_list = [1, 2, 3]

my_list[1] = 4 # Works -> my_list is now [1, 4, 3]

Tuples Indexing

tip

These examples are shown with Tuples, but these also work with Lists.

You can also call elements in a tuple by index:

fruits_tuple = ('apple', 'banana', 'orange')

fruits_tuple[0] # 'apple'
fruits_tuple[1] # 'banana'
fruits_tuple[2] # 'orange'

If you want to convert a tuple to a list, you can use the list function:

my_list = list((1, 2, 3)) # [1, 2, 3]

Similar to lists, you can also slice a tuple:

fruits_tuple[0:2] # ('apple', 'banana')

You can also iterate through a tuple the same way you would with a list.

for fruit in fruits_tuple:
    print(fruit)

Output: apple banana orange

tip

Lists are much easier to work with.

If you want to convert a tuple to a list, you can use the list function:

my_list = list((1, 2, 3))
