install Python in Window

Method:2

First Download Zip file from here  Python
Now extract it in C or any drive, then open the command prompt and go through directory where python zip file kept. just like as 
c: \>  cd c:\programfiles\python\
c: \programfiles\python> setup.py install
or
c: /programfiles/python>python setup.py install

Running setup.py install builds and installs all modules in one run. If you prefer to work incrementally—especially useful if you want to customize the build process, or if things are going wrong—you can use the setup script to do one thing at a time. This is particularly helpful when the build and install will be done by different users—for example, you might want to build a module distribution and hand it off to a system administrator for installation (or do it yourself, with super-user privileges).

For example, you can build everything in one step, and then install everything in a second step, by invoking the setup script twice:

python setup.py build
python setup.py install

Now your python is installed successfully

Install MySQL for Python (MySQLdb) on Windows

It took me quite a while to figure out how to build and install MySQL for Python (MySQLdb) on Windows. I’d better write it down.

Uncompressed MySQL-python-1.2.3c1.tar.gz into a directory. Open a command window (cmd), change to the directory.
Try to run, 
          setup.py build
