Partial function application allows us to create "functions" from other functions with pre-filled arguments. This can be very useful when we want to pipe the output of one function into a function requiring two functions.

Preliminaries



In [5]:

    
from functools import partial

Create A Function



In [6]:

    
def multiply(x, y):
    return x * y

Create A Function With Y Pre-Filled



In [7]:

    
double = partial(multiply, y=2)

Run The Partial Function



In [8]:

    
double(3)









    Out[8]:
