Don't write enumeration values by hand.

In Python, you can use `auto` to do that for you!

`auto` will assign consecutive integers to enumeration members, which is super convenient.

For flag enums, it'll use consecutive powers of 2.

For string enums, it'll lowercase the member names!

Diagram showing two examples of using `enum.auto`: one in a flag enumeration and another in a string enumeration.

Code for the flag example:

```py
from enum import Flag, auto

class Permissions(Flag):
READ = auto() # 1
WRITE = auto() # 2
EXECUTE = auto() # 4

print(repr(Permissions.EXECUTE))
# <Permissions.EXECUTE: 4>
```

Code for the string enumeration example:

```py
from enum import StrEnum, auto

class Direction(StrEnum):
NORTH = auto() # north
SOUTH = auto() # south
...

print(repr(Direction.NORTH))
# <Direction.NORTH: 'north'>
```
