# pyfallback

1. Use `Fallback` to wrap an object with fallback value.

2. Safely do stuff that possibly go wrong.

3. Use the `get()` method to retrieve result.

## Install

```bash

pip install pyfallback

```

## Usage

```python

from pyfallback import Fallback

# fallback

json = Fallback({"key": "value"}, fallback="fallback")

json["key"].get()  # "value"

json["bla"].get()  # "fallback"

# chaining

json = Fallback({"key": "1-2-3"}, fallback="4")

json["key"].split("-")[0].get()  # "1"

json["bla"].split("-")[0].get()  # "4"

# iterating

json = Fallback({"key": [1, 2, 3]}, fallback=[4, 5, 6])

[v.get() for v in json["key"]]  # [1, 2, 3]

[v.get() for v in json["bla"]]  # [4, 5, 6]

# see tests/test_fallback.py for more example 

```
