Python int() Function

Python int() function is used to get the integer value. It returns an expression converted into an integer number. If the argument is a floating point, the conversion truncates the number. If the argument is outside the integer range, It converts the number into long type.

If the number is not a number or if a base is given, the number must be a string.

Syntax of int() Function

It has the following syntax:

Parameters

• x : A number which is to be converted into integer type.
• base: It is an Optional argument if used number must be a string.

Return Values

It returns an integer value.

Examples of Python int() Function

Let's see some examples of int() function to understand it's functionality.

Example 1: Using int() to Convert Float and String into Integer

It is a simple python example which converts float and string values into an integer type. The float value is truncated by the function and returned an integer instead.

Output:

integer values : 10 10 10

Example 2: Using int() Function with Type Checking and Conversion

This example demonstrates how the int() function converts different data types into integers and how their types change after conversion.

Output:

<class 'int'> <class 'float'> <class 'str'>
values after conversion  10 10 10
and types are: 
  <class 'int'> <class 'int'> <class 'int'>

Example 3: Using int() to Convert Different Number Systems

This example demonstrates how the int() function works with numbers from different number systems like binary, hexadecimal, and octal.

Output:

Values after conversion: 2 175 8
and types are: 
  <class 'int'> <class 'int'> <class 'int'>
