What is the difference between a list and a tuple in Python?

The main difference is that a list is mutable (you can change it) and a tuple is immutable (you cannot change it after creating it).

Point	List	Tuple
Brackets	[ ]	( )
Can change items	Yes	No
Speed and memory	A little slower, uses more memory	A little faster, uses less memory
Methods	Many, like append() and remove()	Only count() and index()
Use as dictionary key	No	Yes, if it holds only immutable items

my_list = [1, 2, 3]
my_list[0] = 10
print(my_list)

my_tuple = (1, 2, 3)
my_tuple[0] = 10

Output:

Use a list when the data will change, and a tuple when it should stay fixed. Read more about lists and tuples.
