1.1 install 18

The version here is 2.7.9; https://www.python.org/downloads/release/python-279/

InstallMinGW: Compilers developed for WIndows platforms have gcc functions instead of VC ++;

Http://www.mingw.org/

Http://sourceforge.net/projects/mingw/files/Installer/

Download mingw-get-setup.exe;

Install it on D: \ Pythons \ MinGW;

Run mingw-get.exe in the bindirectory, and select all the packages under MinGW Compiler Suite (the function is not fully selected );

Menu bar Installation-> Apply

Then download and install the SDK;

Download takes a long time. From time to time, it may be interrupted because it cannot be connected to sourceforge. If you fail to download and install it again, check whether D: \ Pythons \ MinGW \ bin is installed, there are many tools;

D: \ Pythons \ MinGW \ bin is added to the environment variable. for verification, the command line executes gcc-v. It is automatically called when the Python compiler needs it;

InstallMSYS

MSYS can provide a Bourne Shell command line execution environment on the Windows platform; Bourne Shell is a standard Unix Shell, that is, bash;

This environment can implement common commands in Linux or Mac OS X, such as cp and rm;

You don't need to download it here. MinGW has it in it. You can install it;

After MinGW and MSYS are installed, the main functions of Linux are available in windows;

1.2 command line 25

9: 29

Enter python in the command line to enter the command line, for example, small computing, such as 1 + 3;

Press enter,PythonParse the program immediately and return the resultThis feature is inherited from the ABC language;

ABC is a teaching language specially designed for non-professional programmers;

Exit the command line: windows, Ctrl + Z (and press Enter); Linux/Mac, Ctrl + D;

1.2.1 custom interactive command line 26

9: 36

Through the Startup File configuration, the environment variable PYTHONSTARTUP will be searched during startup to execute the code in the file;

By default, There Is A. pythonstartup in the main directory. function: Tab auto-completion, command history;

This is implemented based on the readline module (readline library is required );

Check whether the readline module is installed in python;

Command Line input: help (), and then enter modules;

You can also search for the prompt. Enter modules readline;

There is a mini version of readline;

. Pythonstartup, which can be downloaded at https://pypi.python.org/pypi/pbp.scripts;

"G: \ pbp. scripts-0.2.5 \ pbp \ scripts \ pythonstartup. py"

Change pythonstartup. py to. pythonstartup;

But cannot be renamed:

It's okay. Keep the original name and try to configure the environment variable;

Then go to the command line;

The system prompts that no readline module exists;

Download installation, http://newcenturycomputers.net/projects/readline.html

Readline-1.7.win32-py2.6.exe

Install readline;

Check whether python is 32-bit or 64-bit. You can see it when you enter the command line;

The previous readline problem was that version 27 was installed and the registry was not version 26;

Add; regedit,

HKEY_LOCAL_MACHINE \ SOFTWARE \ Wow6432Node \ Python \ PythonCore \ 2.6 \ InstallPath

Re-install:

Installation complete;

Traceback (most recent call last ):

File "D: \ Python27 \ pythonstartup. py", line 2, in <module>

Import readline

File "D: \ Python27 \ lib \ site-packages \ readline. py", line 32, in <module>

Import sys, OS, msvcrt, _ rlsetup

ImportError: DLL load failed: the specified module cannot be found.

I checked it online. In Windows Python 2.7, readline is invalid in windows.

Install pyreadline;

Execute pip install pyreadline;

It seems that the installation module can use pip install;

Verification;

Delete the environment variable. This pyreadline does not need a configuration file;

Automatic tab completion does not take effect;

OS. environ ['home'] keyerror: 'home', because the windows environment does not have the HOME environment variable, which corresponds to HOMEPATH;

Run: import OS

OS. environ. keys () can be viewed;

Change it to HOMEPATH;

Verification:

Yes !!!!!!!!!

Nima

Installing modules is so boring!

Summary: Use the tab to automatically complete the configuration. install pip install pyreadline and pythonstartup. py in version 27:

Http://git.oschina.net/yejq/PythonRel/blob/master/conf/pythonstartup-windows.py

1.2.2 iPython: enhanced command line 27

Extended command line:

· Dynamic Object reflection;

· Call the system shell function in the command line;

· Direct support for program optimization;

· Debugging tools;

Install: pip install ipython

1.3 install setuptools 28

Setuptools: package management system. It releases Python applications, which is equivalent to apt In Debian;

PyPI (Python Package Index): centralized repository;

Currently, it is not a standard library and must be installed;

1.3.1 install with EasyInstall

EasyInstall seems to have been installed;

"D: \ Python27 \ Scripts \ easy_install.exe"

Check whether setuptools is installed;

Seems to have been installed;

1.3.3 integrate MinGW into distutils 31

To compile a program, you can create distutils. cfg in the Directory D: \ Python27 \ Lib;

Content:

[Build]

Compiler = mingw32

In this way, MinGW can be linked to Python. Every time Python needs to compile a package containing C program code, MinGW will be automatically called;

1.4 work environment 31

I use pycharm-professional-4.0.4 here;

1.4.1 install and configure vim 33

Vim is recommended in the book;

Start the MinGW Shell and check whether the MinGW Shell is installed;

Input vim-version;

Not installed;

You can find it in MinGW Installation Manager, MSYS, and MinGW Developer Toolkit;

Install it; the old connection fails, and it has been reinstalled many times;

You can also install gvim;

I am too lazy to configure it here. I have reached out to the party and used the green version of a great God on the Internet;
