Python makes it simple to calculate just how fast a space station needs to spin to generate one G of artificial gravity. In the movie Interstellar, Mathew McConaughey and crew start their wheel-shaped station spinning in space in order to generate one G of artificial gravity, or the same acceleration…

Sometimes what appears to be a simple calculation turns out to be quite complicated. But Python brings back the simplicity! Latitude and longitude coordinates are most often expressed in either decimal degrees, such as on the girl’s arm in the photo above, or in degrees, minutes, and seconds. In Google…

The difference between a Python list and a Python tuple is actually quite simple, especially when explained with a simple example or two. Is It a List or a Tuple? A list has square bracket characters around it… [a,b,3]. A tuple has parenthesis around its content… (a,b,3). This is the most notable difference between the two. What Can Be in a List or Tuple? Most…

As the owner of dozens of calculators, and the author of multiple calculator programming books, I’m now ready to tell you why NumWorks tops my list. As you might know from my other Medium articles, Python programming is my passion. Python is now the world’s most popular programming language, and…

The future is upon us! Pyscript is new and not-yet-for-prime-time, but it promises to be a game changer. Here’s a sample program to give you a head start now. For years now I’ve wished there was a way to use the world’s most popular programming language, Python, such that programs…

There’s a simple way to share a virtual one-time pad for near perfect cryptography. Intercepted messages are even quantum-proof, as long as Alice and Bob acquire the same one-time pad, and nobody else does. Since the early days of cryptography, it’s been a known…

A series of short Python programming examples. Today we’ll create a simple text-based game that’s fun and challenging to play and learn some Python programming tips and tricks along the way. If anyone remembers the old TRS-80 computers, and the CLOAD Magazine programs you could load from cassette tape, you…

A series of short Python programming examples. Today we’ll deal cards from a shuffled deck, with no repeats, and any number of jokers, using two short and sweet functions you can use in your own card game creations. Python is great for creating a wide variety of games, including those…

A series of short Python programming examples. Today we’ll aim a satellite antenna at any geostationary satellite within sight of your location on the earth. Satellites orbit at a speed based on their distance from the earth. The International Space Station is about 250 miles up, and it takes roughly…
