1. Quick Installation

安装包下载:https://www.python.org/ftp/python/3.6.4/python-3.6.4-amd64.exe开始安装：指定安装路径：C:\python27配置环境变量【右键计算机】-->【属性】-->【高级系统设置】-->【高级】-->【环境变量】-->【在第二个内容框中找到 变量名为Path 的一行，双击】--> 【Python安装目录追加到变值值中，用`;`分割】

Ps:
System Defaults ;``C:\python27 , remember that the previous分号

4.2 Tips for using

• Pycharm Configuration
  4.2.1 Setting up multi-version Python support
  Setup steps:
  File->settings->project Test->project Interpreter
  
  4.2.2 Setting the window style and font size
  Setup steps:
  File--Settings->editor-Colors & Fonts
  
  Style of the form after setting
  
  4.2.3 automatically generate file information when creating a Python file
  Setup steps:
  File->setting->editot->code Style->file and Code Templates->python Script
  
  File header information:

#!/usr/bin/env python# -*- coding: utf-8 -*-# @Time    : ${DATE} ${TIME}# @Author  : anChow# @File    : ${NAME}.py

0x05 Example

5.1 Input and output

#!/usr/bin/env python# -*- coding: utf-8 -*-# @Time    : 2018/3/28 18:20# @Author  : anChow# @File    : print.pyname = input("Please input your name: ")print("Hello {0}".format(name))print("Hello " + name)print("Hello %s" %name)

5.2 Basic use of modules

#!/usr/bin/env python# -*- coding: gbk -*-# @Time    : 2018/3/28 18:20# @Author  : anChow# @File    : print.pyimport sysprint("程序名字：{0} ".format(sys.argv[0]))print("参数1 == {0}".format(sys.argv[1]))print("参数2 == {0}".format(sys.argv[2]))

5.2 Pycharm Setting file parameter settings
When no parameters are configured, an error is performed:
