![]() To convert an int to a string you can use the Python str() built-in function. Now, let me show you how to convert an int into a string. The Python interpreter raises a ValueError exception because the value we have passed to the int() function is not a valid base10 number. ValueError: invalid literal for int() with base 10: 'not-a-number-225' ![]() > number = "225"Ĭonfirm that the data type returned is an integer: > type(int(number))Īnd here is what happens if we try to convert into an integer a string that doesn’t represent an int. To convert a string to an int you can use the Python int() built-in function. The process of converting a Python data type to a different data type is also known as type casting. Now we will learn how to convert a string to an integer and vice versa. ![]() In both cases the output of the type built-in function shows that the first variable is an int and the second variable is a string (str).Ĭheck this tutorial if you want to learn what class means in Python. In Python you can represent integer numbers using two data types: int and string. When we talk about integers we refer to decimal whole numbers that are either positive or negative.Įxamples of integers are -1, -3, 0 5, 136. Here we go! How Do You Write an Integer in Python? Then we will analyse a practical example that requires the conversion of a variable from string to integer. We will start by looking at how data type conversion works using int() and str(). ![]() Python also provides the str() built-in function that performs the opposite data type conversion from int to string. This is required when you want to execute mathematical operations that would fail on a variable of type string. The Python int() built-in function converts a string to an integer. This tutorial will clearly show you how to do it. Do you want to learn how to convert a string to an int in Python? You are in the right place. ![]()
