Partial functions in Python
In this lesson, you will learn about partial functions in python and how to use them in your python program.
Partial Functions in Python
Using Partial functions, you can fix a certain number of arguments of a function and generate a new function. Basically, it’s the derivation of a new function from an existing function using which you can reuse the code extensively. It allows us to derive a function with higher-order parameters to a function with fewer parameters with constant values set. The derived function is similar to any other function in Python. Partial functions in python are created with functools library.
Let’s use the partial functions in a python program.

from functools import partial def partial_functions(i, j, k, l): return 1*i + 2*j + 3*k + (4-l) new = partial(partial_functions, 57, 75,67) print(new(76))
