Financial Theory with Python: A Gentle Introduction

The author covers all the basis in the book but the issue is that the book is a bit convoluted. From a code standpoint the author has a habit of defining function inputs as global variables which is really confusing, ie:B = 10...20 lines of code and 10 pages later...def func(b):return b + BWhich is poor habit for writing code, and also quite confusing to read. The other part where the book becomes convoluted is its layout. Essentially each chapter breaks down into a number of sections each covering one mathematical operation or idea. So Variance for instance, you get a quick textbook definition of the term, a mathematical proof then the python code. It would have been nice if the author explained the ideas a bit better with non-proofy terminology, in that same vein it would have been nice if the author could have explained the math in his own words so that the reader could understand the intent of the mathematical operations, and not just some quick algebra. If you have a bunch of proofy definitions of the greeks its hard to look at that and feel like you have a holistic and thorough understanding of the ideas behind them and why it is you're using them.
