How can I get the length of a list in Python?
Richard W

In Python, you can get the length of a list using the built-inlen() function. Here's a detailed explanation of how to obtain the length of a list:

1
2
3
4
5
6

my_list = [1, 2, 3, 4, 5]

length = len(my_list)

print(length)  # Output: 5

In this example,len(my_list) returns the number of elements in the listmy_list. The resulting length is assigned to the variablelength. Thelen() function counts the number of items in any iterable, including lists, tuples, strings, and more. It's important to note that the length of a list corresponds to the number of elements it contains. For an empty list, the length will be 0.

2
3
4
5
6

empty_list = []

length = len(empty_list)

print(length)  # Output: 0

In this case, thelen(empty_list) returns 0 since the listempty_list does not contain any elements. Thelen() function is a simple and efficient way to retrieve the length of a list in Python. It's a useful tool for understanding the size or magnitude of a list, enabling you to perform operations based on the number of elements it contains.
