# Partial Function Applications

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

`from functools import partial`

## Create A Function

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

## Create A Function With Y Pre-Filled

`double = partial(multiply, y=2)`

## Run The Partial Function

`double(3)`

```
