How to Get the Number of Elements in a Python List

In this lesson we want to learn How to Get the Number of Elements in a Python List. Python is high level and interpreted programming language used for general purpose programming. it was created in the late 1980s and has since become one of the most popular programming languages in the world. Python is known for its clear and readable syntax and it is best choice for beginners, as well as its large and active community, which provides support and wealth of third-party libraries for different tasks. Python is used for different types of applications, including web development, scientific computing, data analysis, artificial intelligence and many more.



You can use the len() function to get the number of elements in Python list.




This is an example that demonstrates more complex usage of len() function to get number of elements in list along with other Python features:


In this example we have defined function count_even_numbers that takes list of numbers as an argument. the function uses list comprehension to create a new list even_numbers that only contains the even numbers from the input list. finally the function returns the length of the even_numbers list using the len() function, which gives us the number of even elements in the input list.
