This series of posts is for those who have used a programming language but are not familiar with Python. The first six posts introduced the language. The last post discussed installing and using Python.
In this post we’ll start exploring how to create and use our own data types.

This series of posts is for those who have used a programming language before but are not familiar with Python.
The six introductory posts so far were a bird’s eye view of this popular programming language. Now we’ll dig deeper into the language, beginning with how to download, install, and start using Python.

This series of posts is for those who have used a programming language before but are not familiar with Python. This post concludes the introduction to the language.
This last post of the introductory tour is a grab bag of features I skipped in previous posts. From now on we’ll be digging deeper into specific topics.

This series of posts is for those who have used a programming language before but are not familiar with Python. This fifth post continues the introduction to the language.
In the last post we explored the if-elif-else statement as well as the while and for loop statements. In this post we start exploring functions.

This series of posts is for those who have used a programming language before but are not familiar with Python. This post continues the introductory tour of the language.
In the last three posts [part 1, part 2, & part 3] we toured the key Python data types. In this post we start exploring Python syntax and language statements.

This is the third post in a series for those who have never used Python but have used a programming language before. These posts are meant as an introduction to this delightful and popular programming language.
The first post introduced Python’s most basic data types; the second post introduced its more interesting list-like data types. In this post, we’ll start digging deeper into those list-like data types and what they can do.

This is the second post in a series for those who have never used Python but have used a programming language before. These posts are an introduction to this delightful and popular (free) programming language.
The first post introduced Python’s most basic data types: int, float, str, bool, and None. In this post we’ll meet the list-like data types.

There is a well-known movie line: “This! Is! Sparta!!” To begin the new year, here begins a series of posts under the rubric of “This is Python!” (Python isn’t quite as emphatic about things as Spartans, so it’s just one sentence with one exclamation point.)
These posts are meant for those who have never met Python but who have used a programming language before and know the general concepts. These posts provide a tour of the language.

The last three posts (see here, here, and here) have taken us through Python’s standard tkinter module from the basics to a simple windowed application with a text window for editing and the usual features for loading and saving text files.
I mentioned in the second post that I’d “implement a simple word-counter to replace the calculator parsing and execution code.” That’s what today’s short end-of-the-year post is about.

In the last post we used the Python tkinter module (which is standard) to build a shell window for script-based calculator app. To do anything useful, the shell needs a back-end calculator object to implement script parsing and executing functions.
In this post we’ll look at code for a script-driven prefix calculator that can be easily extended to include other (mathematical) functions.
