The es0EN2.7 implementation introduces its own class methods

System environment: win10

Development environment: JetBrains PyCharm 2017.1.5 x64

Python version: 2.7

If we have an class called DBUtil, which is in A.py (preferably one py file for each class file, to be clear), it should have the init(self) function. It goes like this:

class DBUtil:
  def __init__(self):
    print ' Begin to build DBUtil'

If we need to use this class in other py files to generate the object of this class, we should import this class as follows:

from xxx.A import DBUtil

Where xxx is the path to the corresponding python package. Finally, have fun programming without bug.
