Python library for contracts testing.

This library provides functions for checking argument(`in_contract`) and return value(`out_contract`) of a function.

How to install
--------------------------------------------------------------------------------

``` sh
$ pip install ycontract
```

Example
--------------------------------------------------------------------------------

Example files are [here](https://gitlab.com/yassu/ycontract.py/-/blob/master/tests/test_contract.py)(test file)

Main example is

``` python
from ycontract import contract, out_contract

@contract(lambda a, b: a * b > 0)
def add(a, b, c):
    return a + b


@contract(returns=lambda res: res > 0)
def sub(a, b):
    return a - b
```

And more complex example about in_contract is

``` python
@contract(
    lambda a0: a0 > 0,
    lambda a1, b: a1 > 0 and b > 0,
    {
        "a2": lambda x: x > 0,
        "a3": [
            lambda x: x >= 0,
            lambda x: x < 4,
        ],
        ("a4", "a5"): lambda x, y: x > 0 and y > 0,
    },
    b=lambda x: x > 0,
    contract_tag="tagtag",
)
def add_for_complex(a0, a1, a2, a3, a4, a5, b=1):
    return a0 + a1 + a2 + a3 + a4 + a5 + b
```

Furthermore if you want to be disable, call

``` python
ycontract.disable_contract()
```
