Compare Number with List in Python (2 Examples)

In this tutorial, you’ll learn how to compare a number with a list in Python Programming Language. Comparing a number with a list involves checking if the number exists in the list or determining its position within the list. We’ll explore different methods to achieve this comparison.

The table of contents is structured as follows:

Let’s get started!

Initializing Sample Number and List

Firstly, let’s initialize a sample number and a sample list:

# Initializing a sample number
my_number = 5
# Initializing a sample list
my_list = [1, 2, 3, 4, 5]

This creates a number, my_number, and a list, my_list, containing some elements.

Example 1: Checking Number Existence in List

One way to compare a number with a list is to check if the number and the list have the same value. Here’s an example:

# Checking number existence in the list
print(my_number in my_list)
# True

In this example, we use the in operator to check if my_number exists in my_list. The output shows whether the number exists in the list.

Example 2: Finding Number Position in List

Another way to compare a number with a list is to find the position of the same number value within the list. Here’s how you can do it:

# Finding number position in the list
# 4

In this example, we use the index() method to find the position of my_number within my_list. The output shows the position of the number within the list.

Video, Further Resources & Summary

In this tutorial, we explored different methods to compare a number with a list in Python. We learned how to check the presence of a number in a list and how to find its position within the list. These techniques can be helpful in scenarios where you need to determine the presence or position of a number within a list.
