What is a List in Python?

Before we dive into adding numbers to a list, let’s quickly understand what a list is. In Python, a list is a collection of items that can be of any data type, including strings, integers, floats, and more. Lists are denoted by square brackets [] and can contain multiple elements.

my_list = [1, 2, 3, 4, 5]

In this example, my_list is a list containing five numbers: 1, 2, 3, 4, and 5.

How to Add Number to a List in Python

Now that we know what a list is, let’s learn how to add numbers to it. We can do this using the following methods:

Method 1: Using the append() Method

The append() method allows us to add an element to the end of our list.

my_list = [1, 2, 3]
my_list.append(4)
print(my_list)  # Output: [1, 2, 3, 4]

In this example, we added the number 4 to the end of my_list.

Method 2: Using the insert() Method

The insert() method allows us to add an element at a specific position in our list.

my_list = [1, 2, 3]
my_list.insert(1, 4)
print(my_list)  # Output: [1, 4, 2, 3]

In this example, we added the number 4 to the second position of my_list.

Method 3: Using List Concatenation

We can also add numbers to a list by concatenating another list containing that number.

my_list = [1, 2, 3]
new_list = [4]
my_list += new_list
print(my_list)  # Output: [1, 2, 3, 4]

In this example, we added the number 4 to my_list by concatenating another list containing that number.

Conclusion

Adding numbers to a list in Python is a straightforward process. We can use the append() method to add an element to the end of our list, or the insert() method to add an element at a specific position. Alternatively, we can concatenate another list containing that number using the += operator.

By following this guide, you should now be able to confidently add numbers to lists in Python and unlock more advanced programming concepts!
