下載安裝python安裝工具
下載地址：http://pypi.python.org/pypi/setuptools 可以找到正確的版本進行下載。win7 32位可以下載setuptools-0.6c11.win32-py2.7.exe 。
注意：win7 64位必須使用ez_setup.py進行安裝。方法是下載ez_setup.py后，在cmd下執行 python ez_setup.py，即可自動安裝setuptools。目前沒有直接的exe安裝版本。
注意2：更新了更簡單的辦法，可以直接跳轉到最后面
下載完成后雙擊執行安裝文件，即可在D:\Program Files\python2.7\scripts下安裝easy_install。包含一個easy_install.exe，然后進行環境變量設置，在系統環境變量中做如下設置：
(也就是將D:\Program Files\python2.7\scripts添加到環境變量中）
此時可以在控制台看easy_install 是否安裝上了。

C:\Users\zhuyupeng>easy_install
error: No urls, filenames, or requirements specified (see --help)
上面這種方式不正確，需要使用下面的方式：
C:\Users\zhuyupeng>easy_install virtualenv
Searching for virtualenv
Best match: virtualenv 1.7.2
Processing virtualenv-1.7.2-py2.7.egg

安裝lxml：
C:\Users\zhuyupeng>
如果直接使用：
easy_install lxml
C:\Users\zhuyupeng> easy_install lxml 則會出現下面問題：
make sure the developing packages of libxml2 and libxslt are installed windows
可以使用安裝.egg 文件的方式來安裝：
到
C:\Users\zhuyupeng> easy_install D:\Program Files\Python2.7\lxml-2.3.py2.7.win32.egg
注：對於*.exe 文件這樣也可以安裝
通過這樣的方式就可以安裝成功了：
可以通過在控制台輸入：easy_install lxml 來查看：

C:\Users\zhuyupeng>easy_install lxml

安裝了easy_install 之后安裝python的庫就很簡單了，以后需要安裝python的庫的話則直接在命令行使用
easy_install + libname
比如：
C:\Users\zhuyupeng>easy_install numpy
Searching for numpy
...
Processing dependencies for numpy
Finished processing dependencies for numpy
這是下載下來再安裝的：
C:\Users\zhuyupeng>easy_install "D:\Program Files\Python2.7\matplotlib-1.1.0.win
32-py2.7.exe"
...
Processing dependencies for matplotlib==1.1.0

C:\Users\zhuyupeng>
附一個畫愛心的程序：
""" '17*x^2 - 16*|x|*y + 17*y^2 = 225' """ import numpy as np import matplotlib.pyplot as plt X = np.arange(-5.0, 5.0, 0.1) Y = np.arange(-5.0, 5.0, 0.1) x, y = np.meshgrid(X, Y) f = 17 * x ** 2 - 16 * np.abs(x) * y + 17 * y ** 2 - 225 fig = plt.figure() cs = plt.contour(x, y, f, 0, colors = 'r') plt.show()

更簡單的辦法，只需要輸入幾個命令就ok了：
以下是在IDLE中進行的：
Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> from urllib import urlopen
>>> data = urlopen('http://peak.telecommunity.com/dist/ez_setup.py')
>>> open('ez_setup.py','wb').write(data.read())
>>> exit
Use exit() or Ctrl-Z plus Return to exit
>>>

以下是在windows控制台進行的：
