"Install" Download version python3.4

First of all, to the official website to download the python3.x version, here recommended more than 3.4 version, with the PIP Library, later do not have to download their own

Version 3.4.4: https://www.python.org/downloads/release/python-344/

Settings for multiple versions of Python: http://blog.csdn.net/bskycloud/article/details/50756569

Let sublime text support 2.x and 3.x compilation environment: Http://jingyan.baidu.com/article/6f2f55a155a7d1b5b93e6cd5.html

Install the second-to-last x86-64, which indicates that the Python is installed on the 64-bit system, and the x86 indicates that the 32-bit system is installed.

If you use Google Chrome, the default is to download it yourself. But it was a slow death. "Use thunder download will be faster"

The download is on my Computer--Properties--Change settings--advanced--environment variables--System variables--path there,

1. Right-click My Computer, select Properties, and then tap change settings

2. System Properties--Advanced

3. Select the system variable inside the environment variable, change that path, add the path

For example, my Python.exe is placed in the C:\Python34, then, I add the path is

C: \python34; C: \python34\scripts (note that the semicolon uses the English input method)

4. Since the version of the Pip library that comes with this version is 7.1.2, we need to upgrade it manually.

If your computer has only one version of Python installed, then, (Win+r Open the Run window input cmd),

Go to command line CD c:/python34/scripts (not case), use python-m pip install--upgrade pip

Can.

However, the love toss we usually put the 2.x version of Python in the computer, this time, two versions of the PIP file name are the same,

So using this command will upgrade the previous version of Python's PIP library by default, and we should find a way to get two versions of Python together

Save it.

So. In addition to the previous mentioned, set the system variables, but also put your C:\Python27\python.exe inside the exe text

Renamed to Python2.exe, then renamed C:\Python34\python.exe to Python3.exe
