That's what Google for you. But sadly what Google says is not always true. That's why I asked for personal experience here. It seems there aren't many who has hands-on experience in Python here. Even though I noticed many talked about it in several threads.  I have used PyCharm. It's good, but not because it's developed by JetBrans but it's a full package. But it's too much for an average developer. PyCharm is an enterprise level tool. The downside is because of its nature of the tool pyCharm need lots of power. It can make a normal desktop pc slow. Plus memory usage. So far from what I have figured, VS Code is better for smaller projects.

Agree. If you're a developer with very small to small project, VS Code will be your perfect choice. I would recommend PyCharm too as it's pretty nice from my side, but all downside you mentioned are true.

Notepad++ is also a choice, but it cannot give you fast-complete command, and somehow, the "def" command is black, so I actually cannot see the "def" if I'm not set my laptop to brighter brightness.
For Linux, I recommend GitKraken, if you work with Git, GitKraken allows you to edit on their application, even it's not the purpose of their application, somehow I prefer GitKraken more than the basic text editor.
