# Pipe Function Composition for Python!

> pipe methods in Python!

## Usage:

```python

from simple_pipe import pipe

pipe()()

# your input variable will go through all the methods,

# and then the pipe method will return the final modified variable.

```

## Example:

```python

from simple_pipe import pipe

myvar = 'hello world'

print(pipe(lambda x: x.title(), lambda x: x.replace(' ', ''))(myvar))

>> HelloWorld

```

> You can also create re-usable `compositions` like this:

```python

objects = [{'name': 'John'}, {'name': 'Lisa'}, {'Name': 'Eric'}]

composition = pipe(

    lambda x: safe_set_attribute(x, 'age', 21),

    lambda x: safe_set_attribute(x, 'color', 'green')

)

objects = [composition(obj) for obj in objects]

print(objects)

>> [

    {'name': 'John', 'age': 21, 'color': 'green'},

    {'name': 'Lisa', 'age': 21, 'color': 'green'},

    {'Name': 'Eric', 'age': 21, 'color': 'green'}

]

```
