How to convert a string to an integer in Python Many languages offer built-in cast operators to do just that – to explicitely convert one type to another. Since each data type can be manipulated in different ways, this often means that you'll need to convert it.Ĭonverting one data type to another is also called type casting or type conversion. Sometimes when you're storing data, or when you receive input from a user in one type, you'll need to manipulate and perform different kinds of operations on that data. #This is because of the quotation marks surrounding it #'7' would not be an int but a string, despite it being a number. Integers are not enclosed in single or double quotation marks. They are used to represent numerical data, and you can do any mathematical operation (such as addition, subtraction, multiplication, and division) when working with integers. #Hello world! is a string,enclosed in double quotation marks They are enclosed in single or double quotation marks, like so: fave_phrase = 'Hello world!' Strings are sequences of characters that are used for conveying textual information. In this article, you'll learn how to convert a string to an integer.ĭata types are used for specifing, representing, and caregorizing the different kinds of data that exist and are used in computer programs.Īlso, different operations are available with different types of data – one operation available in one data type is often not available in another. There are different built-in ways to convert, or cast, types in the Python programming language. The ability to convert one data type to another gives you great flexibility when working with information. When you're programming, you'll often need to switch between data types.
