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")
Initialization:
1). Also called Constructor;
2). Function RUN when class instance created;
Example class code with 'SELF' initialization and function calls shown as below:
'Good' and 'Bad' when initialization with 'SELF' in class
To call a function within the same class
Class code with 'SELF' - Part 1
Class code with 'SELF' - Part 2
Class code without 'SELF' - Final
