This tutorial will discuss about a unique way to find length of list in Python.
To find the length of a List in Python, we can use the len()
method of Python. It internally calls the __len__()
method of the object which we pass into it. Also, the List has an overloaded implementation of __len__()
method, which returns the count of number of elements in the list.
So basically len()
method will return the number of elements in the list.
Let’s see some examples,
Example 1 : Get the Lenth of List in Python
We have a list of numbers and we will try to get the count of numbers in that list,
Let’s see the complete example,
listObj = [32, 45, 78, 91, 17, 20, 22, 89, 97, 10] # Get the number of elements in list size = len(listObj) print(f'The length of List "listObj" is: {size}')
Output
Frequently Asked:
- Convert a number to a list of integers in Python
- Convert comma-separated string to List of Integers in Python
- Convert a list of tuples to list of lists in Python
- Print a list without brackets in Python
The length of List "listObj" is: 10
Example 2 : Get the Lenth of List in Python
This is an another example, in which we have a list of strings and we will try to get the number of elements in the list of strings using the len()
method.
Let’s see the complete example,
listObj = ['This', 'is', 'a', 'very', 'short', 'example'] # Get the number of elements in list size = len(listObj) print(f'The length of List "listObj" is: {size}')
Output
The length of List "listObj" is: 6
Summary
So today we learn how to use len()
method to get the size of a list in Python.
