How to Pass Functions with Arguments to Other Functions in Python

Passing Functions with Arguments to Another Function in Python

In Python, functions can be passed as arguments to other functions, even with their own arguments intact. To achieve this, the *args syntax is employed.

When a function accepts a variable number of positional arguments, it packages them into a tuple named *args. This tuple can then be unpacked within the function to access the arguments individually.

Here's an example:

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

# Functions with arguments
def action1():
    # Do something

def action2(p):
    # Do something

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

To pass these functions with their arguments to the perform function, use *args:

<code class="python">def perform(function, *args):
    function(*args)

perform(action1)
perform(action2, p)
perform(action3, p, r)</code>

Within the perform function, *args can be unpacked to access the arguments of the passed-in function. This allows you to call functions with different argument counts seamlessly.
