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.
For example, if you have a list my_list, you can get its length using len(my_list).
Here's an example:
my_list = [1, 2, 3, 4, 5]
list_length = len(my_list)
print(list_length) # Output: 5
This would output 5, which is the number of elements in the list.
