Since you have not mentioned which flavor of Python you intend to work with (Python 2 or Python 3) so here are the useful links for both of them:

For Python 2:

https://docs.python.org/2/tutorial/

For Python 3:

https://docs.python.org/3/tutorial/

I would suggest you to consider registering for MOOC available at Coursera (you need to register yourself but courses are for free and are very useful for beginners):

https://www.coursera.org/courses?languages=en&query=PYTHON

https://www.coursera.org/learn/interactive-python-1/

There is a course available at CodeAcedemy:

https://www.codecademy.com/learn/python

You may use Python and SourceForge repositories for the documentation of PyQuante at these links:

https://pypi.python.org/pypi/PyQuante

Hope this is helpful for you. Best of luck!
