Finish Python installs Setuptools to resolve problems encountered with Matplotlib __python

preparatory work

1. Install Python
2. Install NumPy
3. Set the python environment variable, the system environment variable path after adding C:\Python27; C:\Python27\Scripts Installation Setuptools

Using ez_setup.py automatic installation, save the end code for this page as a "ez_setup.py" file, and double-click to complete the installation automatically. Execute the easy_install command, the following results indicate correct installation, if there is a problem, close the currently open CMD window, reopen and then enter the command.

C:\users\admin>easy_install

Workaround, use the installed Setuptools, execute the easy_install command, install Python-dateutil and pyparsing:
