|Programmer's Python - Objects Become Classes
Everything in Python might well be an object, but if this is the case we need some way of creating new custom objects. How objects become classes and more is explained in this extract from my book, Programmer's Python: Everything is an Object, Second Edition.
Advanced Investment Analysis
Two key functions for gauging the worth of an investment with an irregular cash flow are internal rate of return (IRR) and its counterpart XIRR for an unevenly spaced schedule of cash flows and the modified internal rate of return (MIRR). We look at how to use them in Google Sheets.

From the I Programmer Library
This month sees the publication of the revised second edition of Programmer's Python: Everything Is An Object in which Mike James reveals how Python has a unique and unifying approach with regards to class and objects. This is the first of a set of titles at intermediate level for the programmer who wants to understand what makes Python special and sets it apart from other programming languages, hence the strap line "Something Completely Different - which is, of course, a reference to the Monty Python TV and film brand that inspired Guido Van Rossum to name his new language. The subject is roughly speaking everything to do with the way Python implements objects. That is, in order of sophistication, metaclass; class; object; attribute; and all of the other facilities such as functions, methods and the many “magic methods” that Python uses to make it all work.
This is the second of that Something Completely Different titles and explores the way that data is treated in a distinctly Pythonic way. What we have in Python are data objects that are very usable and very extensible. From the unlimited precision integers, referred to as bignums, through the choice of a list to play the role of the array, to the availability of the dictionary as a built-in data type, Python behaves differently to other languages and this book is what you need to help you make the most of these special features. There are also complete chapters on Boolean logic, dates and times, regular expressions and bit manipulation.
MIke James is now working on the third book in the series, Programmer's Python: Async which not only covers the latest asyncio in depth, but has all you need to know about the many approaches to async that Python provides - threads, processes,futures,tasks, schedulers. This is the book you need to understand all the options, trade-offs and gotchas.
These books aren’t for the complete beginner and some familiarity with both object-oriented programming and Python is assumed, with the first chapter providing a quick recap. They also share an Appendix on using Visual Studio Code from Python.
Programmers think differently from non-programmers, they see and solve problems in a way that the rest of the world doesn't. In this book Mike James takes programming concepts and explains what the skill involves and how a programmer goes about it. In each case, Mike looks at how we convert a dynamic process into a static text that can be understood by other programmers and put into action by a computer. If you're a programmer, his intent is to give you a clearer understanding of what you do so you value it even more.
