Type Casting

Sometimes we need to convert from one data type to another. This is known as type casting.

To perform type casting, Python has three built-in functions (we will learn about functions in a later chapter). These are int(), float(), and str() functions.

The int() function takes in a float or a string and converts it to an integer. To change a float to an integer, simply type int(6.764543). We will get6 as a result as you can see anything after the decimal point is removed. To change a string to an integer, we will type int(“4”), and we will get 4 as an output.

The float() function takes an integer or a string and converts it to a float. For example, if we type float(5) or float(“5”), we will get 5.0 as an output. If we type float(“5.72486”) we will get 5.72486 as an output. As you can see, the quotations marks are removed; hence it is converted into a float.

The str() function converts an integer or float to a string. For example, if we type str(5.2), we will get “5.2” as output.
