I know Python well, but I could build basic things with C++ and Fortran. I use bash a lot too. I know the basics of html and css if those count. And I barely remember some stuff from Matlab

Java/Kotlin and JavaScript/Typescript primarily now. I used to know Visual Basic, PHP, C/C++, and COBOL; but I haven't touched any of them in almost 20 years now.

I've dabbled in a LOT more, but if I had to give an honest answer to languages I could write whatever I want with it the answer is probably C, C++, Python, JavaScript, Java, C#, Bash.

I've been meaning to learn Rust, and all of the people here claiming it's their favorite language is very interesting, but I haven't found the time because it's just not relevant to what I do for work (and not likely to change anytime soon).

Can code in without code completion or checking the docs: C, C#, Scala, F#, SQL (ms server), js/ts, Erlang, Elixir

Have a general idea of but may need to check things about the standard library every so often: Kotlin, Python, OCaml, C++, prolog

Have used in the past but would need to look up the syntax to use again: Go, Rust, Haskell, Java, Gleam

I'm probably missing some from each category though

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.

Too many.

Rust and a bit of Python

In no particular order.
Basic, Python, C , C++, Ruby, Java, Scheme, PHP, ASM, Bash. Does SPSS or CSPro count?

Programming languages in which i have done some project besides basic exercises: Python C# C++ Java

The most used and known is Pyrhon

Professionally, I’ve worked with Python, C++, C# and Java. Also briefly a little bit of Perl.

Outside work, I’ve also done JavaScript, Go and Haskell.

There are many more languages I’ve played around with, but I don’t want to list them all.

In high school I took classes on Visual Basic, C++, and Java, and learned some ActionScript on my own, but I wouldn’t feel confident with any of them nowadays. I suppose I could still write a basic HTML 4 page, but CSS was always a weak point and I don’t think either of those really count as programming languages anyways.

Enough of some to get me into trouble. I edited nethack to give me 95% probability to get wands of death, but then everyone got wands of death. And I still know Hypercard.

Can reliably code in - Python, Lua, R (if it counts)

Can badly code in - C++, Prolog, Visual Basic

Can read the syntax of - Java, JavaScript, GDscript, Basic, SQL

Will never touch - PERL

Python, C#, Rust

Used a bit of C++ and Matlab, but saying I know them is a stretch really.

Don't know any, don't want to know any. Not a good field for my brain or soul.

C#, F#, Visual Basic, SQL, Powershell, JavaScript, Regex, a little Bash, Vimscript and Haskell

Knew, but haven’t used in the last 20 years: C/C++, Java, Object Pascal, Ada

Fluent in c#, c++ and elixir, know a lot of other ones. I'll be to get back to python in a few months for a new job.

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

basic, pascal, c, c#, c++, asm-mips/x86, perl, python, rust, lisp, scheme, slang, java, bash

Python

If you count being able write passable snippets: Java, JavaScript, C,C++,maybe Matlab and bash

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.

• C#
• Java
• Kotlin
• JavaScript/Typescript
• Python
• Go
• Ruby
• SQL

I'm sure I'm forgetting some.

A dozen flavours of BASIC, a few of C, Fortran, Pascal, and one or two others.

Can reliably code in: Swift.

At some point in time have written code in: C++, Java, Python, ActionScript 3, Objective-C, C#, Lua, GDScript.

Python, but we're more just acquaintances, I wouldn't say I know them well or anything

Javascript, Bash and Python. Learning Rust

In no particular order: C C# C++ Perl (been a long time, would need a refresher) Python Rust (favorite) TCL (kill it with fire) JavaScript Typescript Java Kotlin X86 assembly Arm assembly Riscv assembly Bash (shell scripting in general) Dart

Might be some others I haven't touched in while.

I also had the unfortunate experience of having to write windows batch scripts for a month. I can't decide whether I hated TCL or batch more.

Order of learning:

• Garry's mod Wiremod Expression 2
• C#
• C++
• C
• Rust
• Nim
• Lua
• Python
• Javascript/Typescript
• POSIX Shell Script
• Elixir

It's very easy to change languages once you learn the fundamentals. I've worked with more languages but those are the ones I worked with the most with my favourite and goto being Rust.

Ordered by my proficiency:

• perl
• C
• Python
• Java
• Pascal
• Lisp

Python, C, and FORTRAN are my main languages. Some projects have also led me to write code in Java, C#, C++, Javascript, and Lua.
