Overview
Let’s learn about different types of Python Functions in this tutorial. Python functions can be divided into the following types:
- Built-in Functions
- User-defined Functions
Built-in Functions
Built-in Functions that are built into the Python language. Built-in functions are pre-existing functions in Python that can be used without additional coding effort.
Python contains a rich set of built-in functions. Some examples of built-in functions are as follows:
print(), input(), abs(), random(), range(), eval(), etc.
Before invoking the built-in functions, the appropriate module must first be imported into the Python program using the import command.
User-defined Functions
The users define user-defined functions. The Python programmer can develop their user-defined functions depending on their requirement. The programmer defines these functions to perform certain specific operations or tasks.
- Function Definition
The function definition contains the code for the operation to be performed. - Function Call
The function call invokes the function elsewhere in the code or within the function( recursion). The function is called to perform the specific function tasks.
Syntax
The general syntax of user-defined functions is as follows:
def function_name(function_parameters):
“Function documentation string”
function_statement(s)
return(parameter)
Python supports an additional type of function definition known as an anonymous function (lambda function).
