Change Tuple Values

Once a tuple is created, you cannot change its values. Tuples are unchangeable, or immutable as it also is called.

But there is a workaround. You can convert the tuple into a list, change the list, and convert the list back into a tuple.

Example

Convert the tuple into a list to be able to change it:

x = ("apple", "banana", "cherry")

y = list(x)

y[1] = "kiwi"

x = tuple(y)

print(x)

Loop Through a Tuple

You can loop through the tuple items by using a for loop.

Example

Iterate through the items and print the values:

thistuple = ("apple", "banana", "cherry")

for x in thistuple:

 print(x)

You will learn more about for loops in our Python For Loops Chapter.

Check if Item Exists

To determine if a specified item is present in a tuple use the in keyword:

Example

Check if "apple" is present in the tuple:

thistuple = ("apple", "banana", "cherry")

if "apple" in thistuple:

 print("Yes, 'apple' is in the fruits tuple")

Tuple Length

To determine how many items a tuple has, use the len() method:

Example

Print the number of items in the tuple:

thistuple = ("apple", "banana", "cherry")

print(len(thistuple))
