Python is an object-oriented language, but it does not encapsulate all standard classes into libraries like C++. Instead, it carries out further encapsulation. The language itself integrates some classes and functions, such as print, list, dict etc. Brings great convenience to programming

Python uses # for single-line comments, and ＇＇＇ or ＂＂＂” for multi-line comments

Numerical calculation

>>> print "One hour has", 60 * 60 , "seconds" 
One hour has 3600 seconds
>>> result = 12 # 同一行代码利用空格分段使格式更清晰
>>> print result
12

In Python, "" or '' are used to represent strings. It is customary to use '' for a single word and "" for a sentence

>>> print 'Here is Python'
Here is Python
>>> print "Here is Python,too"
Here is Python,too
