In this article, you’ll learn how to find the length of a list in Python. I highly recommend you get the “Python Crash Course Book” to learn Python. To find the length of a list you can use these two methods:
- Method 1: len() method
- Method 2: For Loop
Method 1: length of a list in Python using len() method
This built-in method is mostly used to get the length of an object in Python. In the following example, the len() method is used to find the length of the list.
# Create a list a = [25, 10, 5.2, 43, 'AI'] # Display the length of a list print(len(a))
Output:
5
Method 2: For Loop
You can also find the length of a list using for loop.
# Create a list
a = [25, 10, 5.2, 43, 'AI']
# For Loop to count the items of a list
length = 0
for i in a:
length = length + 1
# Display the length of a list
print(length)Output:
5
