Python Class wz/wzout initializa

Simple code:

Notice of writting class:

1). Begin with 'class' keyword;

2). ALLWAYS Capitalize the First Letter of class Name; 

3). Create class instance just like calling a function.

4). Self used to attach variables and functions to a class; if the 'self' missing, then 'TypeError' occurs:

            TypeError: functionName() takes no arguments....

5). in Python 3.x.x , to use parenthesis '()' after 'print'; EX:

                                  print("something balalalalallallallalla")
