Have you ever tried to learn a new language or do you have friends who've had that experience?
Yes, I tried to learn Python and I even managed to do two Discord bots which are (somewhat) functional, but I'm far to say that I've managed to lean the language completly. There are lots of things to learn on a language as Python.
I also leant PHP on my own and managed to do a website (somehow) functional.
What are some of the steps you would take to learn a new language, and what are some challenges that might arise?
The first steps in learning any computer language is learning the syntax. If you manage to do that, with the experience you gained from previous projects/languages you might be able to create something working. At times you might feel down if the project doesn't work as expected.
What are some things that can help make the process easier?
Video tutorials, experiments and searching questions and problems on Google is a very important resource.
