For Python definitely PyCharm.

Codium. It’s VSCode without the proprietary stuff

Honestly, just try a few of the big ones and see what you like, I feel like with IDEs it’s all about personal preferences and rarely about actual amount of features.

Good ones to start with can be PyCharm and vscodium, but try a few, that’s the best option.

I use PyCharm for work but it's not FOSS or beginner-friendly. PyCharm does have a free community edition which is awesome if you're mostly into FOSS for the $0 aspect.

• https://thonny.org/ - for the first few days of learning and easy setup
• https://www.spyder-ide.org/ - especially good for data science
• https://eric-ide.python-projects.org/ - full-featured general purpose IDE

Codium is fine and technically FOSS although it's association with Microsoft taints it for anyone who still hates MS from the bad old days. Also it's an Electron app.

Netbeans for java was good to me as a student.

Vim/neovim

with the rise of LSP, i feel that ides have become less necessary. get an editor that you like, add an LSP client if there’s not one built-in, then install the server for your language.

I use Helix. It’s kinda like a preconfigured Neovim. I really like it, my only complaint is that it (currently) doesn’t have a filetree

For python PyCharm is unbeatable.

Eclipse Theia if you already know VSCode.

It copied the interface and functionality and is compatible with most VSCode extensions. Available as an AppImage on Linux.

Geany www.geany.org

My husband, who mostly codes in assembly these days (he’s mostly retired so his hobby is old atari, amstrad, and spectrum computers), went from VSCode, to Sublime, to now Kate. He prefers to use 100% open source apps, without strings attached. VSCode is nice, but it has lots of weird stuff in it that aren’t necessarily up to the spirit of open source. So Kate works perfectly for him, although VSCodium would do well as well (it’s just that Kate has better syntax highlighters for his weird assembly). Also VSCode/ium is using about 250 MB of RAM, while Kate about 45 (and Sublime only about 32).

I really like Kate as an advanced editor with syntax highlighting, auto-completion, plugin support. I would then use the Terminal pane at the bottom to run my code during development.

However, if you want a full IDE with included dependency management, test runner, and debugger it’s probably not enough.

One of my professors said you don’t need an IDE, the Linux system already is a development environment. Not sure that I fully agree with that, especially thinking of things like Android Studio that include the virtual machine smartphone, but it’s still an approach thing that is worth trying out.

Emacs and geany

I use Vim ;)

Python itself provides IDLE, which is good enough for beginners. thonny.org is another good one for beginners.

As mentioned by others, Jetbrains is good for many languages. www.kdevelop.org is another option.

vim/nvim is really great

Because people ask for an IDE, rather than an editor, I will say :

Vim + terminal(s) + containerization (e.g. Docker CLI, Python venv) + live reloading (e.g. nodemon or inotify or in the browser using e.g. server side events) + repository management (e.g. git in CLI to juggle between branches, push/pull local/remotely)

IMHO this is very VERY light (0 wait even on a RPi Zero) and yet very flexible.

Also most of that can be “saved” via e.g screen the CLI tool, allowing to have named windows in a terminal and a lot more than to e.g. screen -raAD, locally or remotely.

I’m slowly learning Emacs, I’d say I like it but it’s a lot of config work and I wouldn’t recommend it to somebody who hasn’t programmed before.

Neovim! Here is a good video to get started TJ DeVries. If you just want to give it a shot there are a lot of preconfigured options like lunar vim or NVchad.

I’m a big fan of vim/neovim with nerdtree and airline added in.

I’ve also been tryingourt Zed recently, it natively supports vim keybindings, so my workflow hasn’t changed, but its lightning fast (programmed in rust) compared to vs-codium (an electron app)
