WRDS-Py is a library for extracting data from WRDS data sources and getting it into Pandas. The library allows users to access SAS/SHARE and extract data using SQL statements. The data that is returned is read into a Pandas data frame.
Mac OS/Linux
$ python setup.py install
Windows
The WRDS-PY package requires Pandas and Psycopg2. Binaries of these can be found here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#psycopg
Once the two required packages are installed, you can run $ python setup.py install
