With the Termux + PyPi repositories you can do basically the same as you would do in a normal Linux terminal and it’s great.
I’m not a fan of having many apps on my phone and with Termux I can have yt-dlp, ffmpeg and even magick to do almost anything I want, it’s just great and I don’t know how Termux is not more popular, I hope more people will find sense in it and use it too if they see a use for it.
Mine uses the normal Android keyboard with an extra row of modifier keys (ie: Esc, Ctrl, etc) added by Termux above it that you often need in CLI.
Mine shows the standard keyboard bitmap, but swipe typing and predictive text don’t work. I have to tap each character. It’s tolerable for some things I guess. I should use it more.
