# 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)
```

```
