Get size of list python
In Python, you use a list to store various types of data such as strings and numbers. Show
A list is identifiable by the square brackets that surround it, and individual values are separated by a comma. To get the length of a list in Python, you can use the built-in Apart from the In this article, I will show you how to get the length of a list in 3 different ways. You can use the native for loop of Python to get the length of a list because just like a tuple and dictionary, a list is iterable. This method is commonly called the naïve method. The example below shows you how to use the naïve method to get the length of a list in Python
How to Get the Length of a List with the len() FunctionUsing the This is more straightforward than using a for loop. The syntax for using the The code snippet below shows how to use the
How to Get the Length of a List with the length_hint() FunctionThe
The syntax for using the The example below shows you how to use the
Final ThoughtsThis article showed you how to get the size of a list with 3 different methods: a for loop, the You might be wondering which to use between these 3 methods.

Get started The list in Python is a collection data-type that is ordered and changeable. A list can have duplicate entry as well. The Python len() method is used to find the length of any object. In this article, we will learn how to find the length of list in python programming in the following sequence:
List in PythonA list in Python is implemented to store the sequence of various types of data. However, there are six data types in Python that are capable of storing the sequences but the most common and reliable type is a list. To learn more about python you can join our Master Python programming course. A list is defined as a collection of values or items of different types. The items in the list are separated with a comma (,) and enclosed with the square brackets []. It is defined as follows: list1 = ['edureka', 'python', 2019]; list2 = [1, 2, 3, 4, 5 ]; list3 = ["a", "b", "c", "d"]; If you want to learn Artificial Intelligence and Machine Learning in-depth, come to us and sign up for this Post Graduate Diploma AI and ML courses. How to Find the Length of List in Python?There are two most commonly used and basic methods that are used to find the length of the list in Python:
Len() MethodThere is a built-in function called len() for getting the total number of items in a list, tuple, arrays, dictionary, etc. The len() method takes an argument where you may provide a list and it returns the length of the given list. The len() method is one of the most used and convenient ways to find the length of list in Python. This is the most conventional technique adopted by all the programmers today.

Syntax: len(list) The List parameter is a list for which the number of elements are to be counted. It returns the number of elements in the list. Example: ListName = ["Hello", "Edureka", 1, 2, 3] print ("Number of items in the list = ", len(ListName)) Output:5 Naive MethodThe len() method is the most commonly used method to find the length of the list in Python. But there is another basic method that provides the length of the list. In the Naive method, one just runs a loop and increases the counter until the last element of the list to know its count. This is the most basic strategy that can be used in the absence of other efficient techniques. Example: ListName = [ "Hello", "Edureka", 1,2,3 ] print ("The list is : " + str(ListName)) counter = 0 for i in ListName: counter = counter + 1 print ("Length of list using naive method is : " + str(counter)) Output: The list is : ["Hello", "Edureka", 1,2,3] Length of list using naive method is : 5 This was all about finding the length of list in Python. The len() method is the most popular method. Whereas, you can also use the basic method of finding the length with the help of Naive Method. With this, we have come to the end of our article.
