The built-in Python functions are pre-defined by the python interpreter. There are 68 built-in python functions. These functions perform a specific task and can be used in any program, depending on the requirement of the user.
What are Python Functions?
There are three types of functions in the python programming language. These are:

How many Functions are in Python?
There are three types of functions in the python programming language. These are:
- Built-in functions- There are 68 built-in functions in the Python programming language.
- User-defined functions- To define a user-defined function, the def keyword is used Â
- Anonymous functions- these are also known as lambda functions.Â
What is a Function in Python for example?
A function is a collection of related statements that performs a specific task. To define a function, the def keyword is used.Â
Here is the syntax for the function in Python:
def function_name(parameters):
    """docstring"""
    statement1
    statement2
    ...
    ...
    return [expr]
What is a Function Statement in Python?
A function is a code block that only executes when it is invoked by the user.
To define a function in python, the def keyword is used.Â
For example:
def function1():
  print("Hello from the other side")
How to Call a Function in Python
To call a function in Python, the user needs to write the name of the function followed by the parenthesis.Â
Example:
def function1():
  print("Hello from the other side")
function1()
