How do I get the number of elements in a list (length of a list) in Python?

To get the number of elements in a list in Python, you can use the len() function.

Here's an example:

Get the number of elements in a list in Python using len function

my_list = [1, 2, 3, 4]
num_elements = len(my_list)
print(num_elements)  # Output: 4

<div class="alert alert-info flex not-prose"> <span class="hidden md:block">Watch a video course </span> Python - The Practical Guide</div>

You can also use the len() function to get the length of other types of sequences, such as strings and tuples.

Get the number of elements in a tuple, or the number of characters inside a string, using len function in Python

my_string = "hello"
string_length = len(my_string)
print(string_length)  # Output: 5

my_tuple = (1, 2, 3)
tuple_length = len(my_tuple)
print(tuple_length)  # Output: 3
