I'm a retired programmer.
A recent attempt at writing a Python script
showed me that I have forgotten a LOT of the syntactic details. With that in mind, these are the langs that I have used professionally. "Know" might be an exaggeration at this point.
HP basic
Fortran
C
C++
C#
Java
Perl
Python
HTML (if that counts)
Awk/sed
I know Python, R, the STATA ado-language (a horrible proprietary progamming language), MATLABs language, Javascript and some minimal C++. What I know really well though is R and Python. So typical profile for a (data) scientist.
I'm fluent in C#, C++, C, Rust, Java, Python, and JavaScript, plus Sass/CSS, HTML, and SQL, although I'm not sure they count as full languages. I've also worked with Dart, Kotlin, Assembly (various flavors), Bash scripts, F#, Perl, and Lua.
I've probably done more but can't remember them all offhand.
I know that they're not really "programming languages" but I've used a little bit of Batch, HTML and CSS in the past and I also use a little bit of Bash occasionally.
I use/used Bash and Batch mostly for creating desktop shortcuts or for running games/apps with specific parameters.
For HTML and CSS I used to maintain my own website a few years ago through Neocities but I deleted it after about 9 months because I never got any positive feedback from the people who viewed it and I lost interest. I do occasionally think about creating another website under a different name but I have no idea what I'd do with it.
