## Python Tilde Operator

`~`

in python will invert the value. The actual method depends on the implementation of `__invert__`

method of the argument.

Let’s start with the numbers.

```
~10 # -11
~-10 # 9
~1 # -2
~-1 # 0
~0 # -1
```

The case for `True`

and `False`

```
~True # -2
~False # -1
# which are the same as
~1 # -2
~0 # -1
```
