# deferpy
```
Deferred function calls are pushed onto a stack. When a function returns, its deferred calls are executed in last-in-first-out order.
```
[The Go Blog](https://blog.golang.org/defer-panic-and-recover) has a good explanation of the behavior of `defer`. This package attempts to recreate the behavior as closely as possible.
## Installation
```bash
$ pip install deferpy
```
## Usage
Check out the `tests` to see more examples.
```python
>>> from deferpy import defer
>>> @defer()
... def function(a, b, c):
... function.defer(print, a)
... function.defer(print, b)
... function.defer(print, c)
... return a + b + c
...
>>> print(function(1, 2, 3))
