Partial functions allow us to fix a certain number of arguments of a function and generate a new function.

Python partial functions are a powerful tool for creating new functions from existing ones with pre-specified argument values. A partial function is a function that is created by fixing some of the arguments of an existing function. This can be useful in situations where we need to call the same function with different argument values multiple times.

To create a partial function in Python, we use the functools.partial function. This function takes a function and one or more arguments as input and returns a new function with the specified arguments fixed. The new function can then be called with the remaining arguments to produce the final result.

Here is an example: 

from functools import partial

def add_numbers(x, y):
    return x + y

add_five = partial(add_numbers, 5)

print(add_five(3)) # Output: 8

In the above example, we create a new function called add_five by fixing the value of the first argument to 5 using the partial function. We can then call this function with the remaining argument 3 to get the result 8.

Partial functions can be especially useful when dealing with functions that have many arguments. By fixing some of the arguments using partial functions, we can reduce the number of arguments that need to be specified each time the function is called. This can make the code more concise and easier to read.
