## How python sees True and False

For python `True==1` and `False==0`

```python
1 and False //False
0 and 1 //False
1 and True //True
1 or 0 //True
```

## Other boolean-operations:

These are other boolean operations which are not part of the Python language, you will have to define them yourself or use the boolean expression within the parenteses.
