Python is a computer programming language. Computer programming language and our daily use of natural language is different, the biggest difference is that natural language in different contexts have different understanding, and the computer to perform tasks according to the programming language, you must ensure that programming language written in the program can never be ambiguous, so, any programming language has its own set of syntax, The compiler or interpreter is responsible for translating the syntax-compliant program code into the machine code that the CPU can execute, and then executing. Python is no exception.

Python's syntax is simple, indented, and the code is written like this:

# print absolute value of an integer:a = 100if a >= 0:    print aelse: print -a

# 1. Data type, variable

# # #整型
