Two ways Python installs third-party packages

Recent study of QQ space, micro-bo (reptile) Simulation login, found that all involved in RSA algorithm. The next RSA package (third-party package) is required. Toss for a long time, mainly feel online a lot of articles on the specific where to write the operation is not clear. Here's a summary, lest you forget it someday.

The first method (do not use PIP or Easy_install):

STEP1: Find the required package on the Internet and download it down. eg. Rsa-3.1.4.tar.gz

STEP2: Unzip the file.

STEP3: command line tool CD switch to the directory of the package you want to install, locate the setup.py file, and then enter the python setup.py install

The second method (using PIP or Easy_install):

Open cmd directlyand hit Pip install RSA.

In particular, the above two methods are directly into the cmd, not the Python shell, and do not have to go into the python! in cmd
