There is a high probability that you will find some one has already documented their own experiences with python in the form of Books, Blogs or YouTube Video etc. Today the Scipy and Sympy user guides and Lecture notes combined is in excess of 5000 pages. That is enormous capability available to everyone to carry out their activity in Quantitative Field with Python. And it is growing by the day. It is these libraries that make Python so Rich!!
