Python – Convert Integer to String

In this tutorial, we will look at how to convert an integer (int datatype) in Python to a string with the help of some examples.

Integer as string in Python

Whole numbers in Python are generally stored using the int type and in some cases as a string. For example, “150” is a string containing the number 150. You can use the string isdigit() function to check if a string represents a number or not.

# string storing a whole number
s = "150"
# check if string contains numeric value



With numbers stored as strings, you cannot apply numeric computations to those string numbers. For example, if you add “150” and “50” using the + operator, it will be treated as a string concatenation operation resulting in “15050” and not “200”.

# addition of numeric values
# addition of numeric string values



Thus, a common use case for storing numbers as strings is when you don’t need to perform arithmetic computations on the number. For example, storing numeric Id values as strings or when you want to perform string operations such as slicing, etc. on the numbers.

Let’s look at some examples of using the above syntax to convert an integer value to a string.

Here we apply the str() function on an integer value 150.

# integer value
num = 150
# convert int to string
s = str(num)
# display the string and its type


<class 'str'>

You can see that we get 150 as a string.
