How to Pass Functions with Arguments to Other Functions in Python?

Passing Functions with Arguments in Python

In Python, functions are first-class objects, which means they can be passed as arguments to other functions. This allows for greater flexibility and modularity in code.

Consider a scenario where you have multiple functions with different arguments and you want to pass them to a central function for execution.

Passing Functions with Arguments

To pass functions with arguments to another function, you can use the *args syntax. This allows you to pass any number of arguments to the function.

For example, let's define a function called perform that takes a function as an argument and executes it:

<code class="python">def perform(function):
    function()</code>

Now, let's define three functions with different arguments:

<code class="python">def action1():
    # Do something

def action2(p):
    # Do something with p

def action3(p, r):
    # Do something with p and r</code>

To pass these functions with arguments to the perform function, we can use the following syntax:

<code class="python">perform(action1)
perform(action2, p)
perform(action3, p, r)</code>

In this example, action1 is passed without arguments, action2 is passed with one argument p, and action3 is passed with two arguments p and r.
