Computers are mostly used to store information and extract information from it. Python is one of the most powerful programming languages. We can use Python to get computers to do most of the routine processes. This blog is all about ” Tips on getting Length of List in Python”. Let’s read it to get more useful information and open your knowledge.
What is a list in Python?
Python uses lists to save the sequence of different sorts of data. There are six data types in Python that can store sequences, but a list is the most popular and dependable kind. A list is specified as a grouping of values or items of various categories. The list’s items are surrounded in square brackets [] and separated by commas (,).
Python List Example
This is an instance of a Python list. We also have to figure out how many elements are on the List.
ListExample = ["One", "Two", "Three", "Four", "Five"];
How Can You Get Length of List in Python?
Method 1: Use len()
The len() technique in Python is used to determine the length of a list. Simply utilize your list in the len() function to get the length of your list in Python.
Python Len() Syntax
The len() method takes a list as an argument and returns the number of elements in the list. As an example, consider the following.
countOfList = len(your_list);
or
countOfList = len(["One", "Two", "Three", "Four", "Five"]);
or
ListExample = ["One", "Two", "Three", "Four", "Five"];
countOfList = len(ListExample);
Result
ListExample = ["One", "Two", "Three", "Four", "Five"];
print("The length of the list is:", len(ListExample));
## OutPut
The length of the list is: 5
The len() technique in Python is utilized to determine the number of elements in a list. Simply utilize your list in the len() function to get the length of your list in Python.

Method 2: Use Naive
Another way to getting length of list in Python is using Naive.
To determine the total elements of list by using the Naive technique, you simply need to run a loop and extend the counter to the last member of the list. In the absence of other effective strategies, this is the simplest method that can be applied.
For example:
ListName = [ "Hi", "Lisa", 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 : ["Hi", "Lisa", 1,2,3]
Length of list using naive method is : 5
Method 3: Use length_hint()
A less well-known method for determining list length is using length_hint(). This specific method is specified in the operator class and it is also capable of revealing the number of elements in the list.
For example:
from operator import length_hint
db = ["MySQL", "PostgreSQL", "SQLite", "Redis", "Cassandra"]
print(f"Length: {length_hint(db)}")
Output
Length: 5
