Python advanced Programming (1)-Preparing for work

1.1 Installation 18

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

installation MinGW: For the development of Windows platform compiler, there are various functions of GCC, instead of VC + +;

http://www.mingw.org/

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

Download Mingw-get-setup.exe;

installation to D:\Pythons\MinGW;

Run the Mingw-get.exe in the bin directory and tick all the packages under MinGW Compiler Suite (no full selection);

Menu Bar Installation->apply

then download and install;

Download will take a long time, and every now and then because not connected to the SourceForge and interrupted, failed to re-download the installation can be, after installation look at D:\Pythons\MinGW\bin, there are many old tools;

D:\Pythons\MinGW\bin is added to the environment variable; validation, command line execution gcc-v;python The compiler will automatically call when required;

installation MSYS

Msys can provide a Bourne shell command-line execution environment on the Windows platform; the Bourne shell is a standard UNIX shell, which is bash;

This environment can be implemented in Linux or Mac OS X operating system common commands, such as CP, RM, etc.;

There is no need to download here, MinGW inside, installation is possible;

After installing MinGW and Msys, the main functions of Linux are available in Windows;

1.2 Command line 25

9:29

command line input python into the command line, example: small computing, such as 1+3;

Press ENTER,python immediately resolves the program and returns the result , which is inherited from the ABC language;

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

Exit command line: Windows,ctrl+z (then enter); linux/mac,ctrl+d;

1.2.1 Customizing interactive command line 26

9:36

By starting the file configuration, the environment variable Pythonstartup will be found at startup to execute the code in the file;

The default is a. Pythonstartup in the home directory; function: Tab auto-complete, command history;

This is implemented based on the ReadLine module (requires ReadLine library);

See if Python has the ReadLine module installed;

Command line Input: Help (), then enter modules;

Look at the hint can also search; input modules ReadLine;

There is a mini version of the ReadLine;

. Pythonstartup, can go to https://pypi.python.org/pypi/pbp.scripts, download;

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

pythonstartup.py renamed to. Pythonstartup;

But not renamed:

Okay, keep the original. Try, configure environment variables;

Then enter the command line;

Hint no readline module;

Download and install, http://newcenturycomputers.net/projects/readline.html

Readline-1.7.win32-py2.6.exe

Install ReadLine;

See if Python is 32-bit or 64-bit, which can be seen when the command line enters;

The previous ReadLine problem is that the 27 version is installed and the registry does not have a 26 version;

Plus, regedit,

Hkey_local_machine\software\wow6432node\python\pythoncore\2.6\installpath

Re-install:

Installation completed;

Traceback (most recent):

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

Import ReadLine

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

Import sys, OS, MSVCRT, _rlsetup

Importerror:dll load failed: The specified module could not be found.

Checked online, under Windows Python 2.7, ReadLine is not valid under Windows.

Install a pyreadline;

Execute pip install pyreadline;

It seems that the installation module can use PIP install;

Authentication

Delete the environment variable, perhaps this pyreadline does not have the configuration file at all;

TAB Auto-completion does not take effect;

os.environ[' Home ' keyerror: ' Home ' because the Windows environment does not have a home environment variable, corresponding to the HomePath;

Execution: Import OS

Os.environ.keys () can be viewed;

Then change to HomePath suppress;

Verify:

OK!!!!!!!!!

Nima

Put a module all this hole dad!

Summary: To use tab auto-completion, version 27 installs pip install pyreadline,pythonstartup.py content:

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;

· Invoking the system Shell function on the command line;

· Direct support for program tuning;

· Debugging tools;

Installation: Pip Install Ipython

1.3 Installing Setuptools 28

Setuptools: Package management system, publish Python application, equivalent to Debian in the apt;

PyPI (Python package Index): Centralized warehouse;

is not the standard library, but also to install;

1.3.1 Installation with Easyinstall

Easyinstall seems to have been installed;

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

See if there are any setuptools installed;

It seems to have been installed;

1.3.3 integration of MinGW into Distutils 31

When the program needs to be compiled, the D:\Python27\Lib directory can be created; distutils.cfg;

Content:

[Build]

compiler = Mingw32

This makes it possible to link MinGW to Python, and each time Python needs to compile a package containing C program code, it automatically calls MinGW;

1.4 Working Environment 31

Here I use pycharm-professional-4.0.4;

1.4.1 Vim installation and Configuration 33

The book recommended using Vim;

Start the MinGW shell to see if it is installed;

Input vim-version;

Not installed;

In MinGW installation MANAGER,MSYS,MINGW Developer toolkit inside can be found;

Install it; the old connection failed, re-installed several times;

can also install gvim;

Here too lazy to match, long live the party, with a big God on the Internet green version;

1.4.2 IDE

Install eclipse with Pydev plug-in;

Marketplace;

Install it;

Not even up;

Try the install Updates;
