If you try the following in your console:

```
~True
```

you'll get "-2" 😳. Why?

Think about `bool`

, you'll find that it is numeric in nature - It can hold two values, "True" and "False", and they are just "customized" versions of the integers 1 and 0 that only print themselves differently.

So `bool`

is a subclass of `int`

:

```
>>> type(True)
<class 'bool'>
>>> isinstance(True, int)
True
>>> True == 1
True
>>> True is 1 # they're still different objects
False
```

Having that said, `~True`

evaluaes to:

```
~True == ~int(True) == ~1 == -2
```

`~`

simply flips the bits. So:

```
1 = 00000001
~1 = 11111110
```

which is -2 in two's complement. Verifying that:

Flip all the bits, add 1 to the resulting number and interpret the result as a binary representation of the magnitude and add a negative sign (since the number begins with 1):

```
11111110 → 00000001 → 00000010
↑ ↑
Flip Add 1
```

Which is 2, but the sign is negative since the MSB is 1.

I hope that was clear :)
