The *opener* is supported on Python 2.7, as well as Python 3.4 and above.

## How to use

### Example 1

![Three Digits Open the Lock Puzzle Example](https://raw.githubusercontent.com/arsho/opener/master/examples/open_the_lock_example_1.png)

The above figure outlines a three digits *Open the Lock* puzzle. A valid unlock key of the above puzzle is: `679`

[example_1.py](https://github.com/arsho/opener/blob/master/examples/example_1.py) shows how to use [opener](https://pypi.org/project/opener/) package to solve the above puzzle.


Solution of the above *Open the lock* puzzle:

```python
from opener import get_keys

number_of_positions = 3
invalid_digits = (5, 2, 3)
similarity_conditions = (
    ([9, 6, 4], 2),
    ([2, 8, 6], 1),
    ([1, 4, 7], 1),
    ([1, 8, 9], 1)
)
invalid_positioned_values = ((9, 1), (6, 8, 4), (4, 6, 7))
valid_positioned_values = ((1,), (8,), (9,))
unlock_keys = get_keys(number_of_positions,
                       similarity_conditions,
                       invalid_digits,
                       invalid_positioned_values,
                       valid_positioned_values)
for key in unlock_keys:
    print(key)
    # 679
 ```

### Example 2

![Four Digits Open the Lock Puzzle Example](https://raw.githubusercontent.com/arsho/opener/master/examples/open_the_lock_example_2.png)

The above figure outlines another *Open the Lock* puzzle with four digits combination. A valid unlock key of the above puzzle is: `9876`

[example_2.py](https://github.com/arsho/opener/blob/master/examples/example_2.py) shows how to use [opener](https://pypi.org/project/opener/) package to solve the above puzzle.


Solution of the above *Open the lock* puzzle:

```python
from opener import get_keys

number_of_positions = 4
invalid_digits = (5, 1, 2, 4)
similarity_conditions = (
    ([3, 5, 4, 8], 1),
    ([4, 6, 7, 1], 2),
    ([3, 7, 8, 1], 2),
    ([8, 3, 9, 7], 3),
    ([2, 9, 3, 4], 1),
    ([5, 1, 3, 6], 1),
)
invalid_positioned_values = ((3, 8, 2), (5, 7, 3, 9),
                             (4, 8, 9, 3), (8, 1, 7, 4))
valid_positioned_values = ((5,), (1,), (3,), (6,))
unlock_keys = get_keys(number_of_positions,
                       similarity_conditions,
                       invalid_digits,
                       invalid_positioned_values,
                       valid_positioned_values)
for key in unlock_keys:
    print(key)
    # 9876

 ```
