0 Basic python-The interpretation process of Python and Python

Today's first contact with Python, it is very magical, especially there is a "*" syntax, directly replace the loop, really very convenient

Here is my first contact with Python-written code: only a short print

Import Sysprint (sys.platform) # System platform Print (2**100) x= "Hello World \ n" Print (x*8) #打印8次

Output Result:

>>> ================================ RESTART ================================
>>>
Win32
1267650600228229401496703205376
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World
Hello World

This python can run in Python's idle, or run through the Shell Live DOS window, I use the trial Win32 platform, so the DOS window allows

I saved the above code as a python-ch3-001.py file and placed it under the C:/python34 directory and ran it through the Python command.

Now let's talk about the Python interpretation process,

See

xxx.py: We have compiled a good python file

Xxx.pyc:python Compiler-Compiled files

Pvm:python running a virtual machine

The files we write are compiled into PYC files by compilers, and then PYC files run on PVM, so Python is generally a little slower than static languages such as java,c, but we generally don't feel
