Q. What code above will print out ?

Answer : We are learning Python !

Unlike other programming languages, Python does not require semicolon and specific data type declaration. Python has a lot more easier tools than any other programming languages. The biggest good point of Python is it is free and fast.

We have just learned how to use print in Python. Hope to see you again at my blog anytime you want ! FAIR ENOUGH. See you again.
