Anyone who played with BASIC on personal computers in the 1970s and 1980s will recognize the importance of the BASIC language for noodling around. The creators of BASIC intended it to be used to teach computer programming concepts to FORTRAN students at Dartmouth College, but noodling around made BASIC ideal for teaching other concepts in science, engineering, and math everywhere.
BASIC on personal computers of the 1970s was usually implemented in ROM, and every implementation was different (Apple2, TRS-80, HeathKit-H8). Starting with the IBM-PC in 1981, Microsoft, began publishing 16-bit software products like GW-BASIC (1983), QuickBASIC (1985) and QBASIC (1991) which worked well on 16-bit operating systems like MS-DOS (1981) up through Windows-3.11 (1992). These 16-bit language interpreters were also supported on 32-bit operating systems starting with Windows-95 through to Windows-7 via a OS technique known as THUNKING.
The big problem today is that 64-bit computers run 64-bit operating systems, like Windows-10, where 32-bit programs are THUNKED but not 16-bit programs. Technical work-arounds exist including "setting up a virtual machine" on your 64-bit OS but why go to all that bother when all you want to do is noodle around? Perhaps it is time to ditch BASIC for Python
Many people reading this will not know that Python was first created in 1990 to replace BASIC. Today, Python is primarily used to do server-side scripting on the internet/world-wide-web but also has many other uses. Here is a short list:
Imagine using numbers this size index your data arrays

Easter |
compute the date of Easter for any given year | it all starts with determining the date of the first full moon on, or after. the Spring equinox. |
fun with floats | fun with floats and decimals | be careful how you initialize float and decimal data; this program also shows how to properly use the exec() function in python3 |
money rounding | money rounding demo | required for GAAP (generally accepted accounting principles) |
pix-of-day | picture of the day generator | extracts picture-of-the-day info from a relational database which is then passed JavaScript) click here to see it in action: http://neilrieck.net (picture is in t 1) the top right corner will show a NASA chart for last month's CO2 readings 2) eight seconds later, the image and text will switch to something extracted from my database 3) eight seconds later the picture switches back to the CO2 readings 4) this will cycle back an forth for ten iterations 5) punch PF12 on your browser then click CONSOLE to observe log messages |
Anyone considering a course on machine learning or deep learning should learn Python immediately where most examples will include one (or more) of these free Python libraries
NumPy | Library to add array support to Python2 Also contains routines for doing matrix mathematics |

The roots of artificial intelligence (and expert systems, and machine learning) go back to the 1940s and 1950s so contain a lot of non-computer terminology. Modern computer technologists wishing to learn more might wish to start here:
