There are many simple examples about python. The purpose is only to record my note.

Sometimes we will see this below.

from __future__ import print_function

This is meaning that if you use python 2.x version, it will use the python 3.x version function. (New features from next version)

Please check the example.

Use this Command:

python future_demo.py

Output:

  File "future_demo.py", line 4
    print 'you are good'
                       ^
