3.

# Enum.auto
>>> from enum import Enum, auto
>>> class Color(Enum):
... red = auto()
... blue = auto()
... green = auto()
... 
>>> list(Color)
[<Color.red: 1>, <Color.blue: 2>, <Color.green: 3>]

Tips

After the first build installation, you may find that the arrow keys fail after entering python3.6.

The reason is that the readline library is not installed.

Solution:

Install readline library

sudo apt-get install libreadline-dev

After installing, recompile python and install it again once.

cd Python-3.6.0
./configure
make
sudo make install
