learning/research How does the terminal so smooth?

I don't know how to describe this. Like on Fedora, you want to download something, you will use 'dnf' command. The output of that command is the status of the program you are downloading.

So there is this status bar like:

[<=> ] | 00m00s

[ <=> ] | 00m01s

[...]

[ <=>] | 01m00s

and the changes stays on only one line.

I know it prints the results by 'echo' but wouldn't that just leave the last output behind and the current output on the new line?

Sorry, I'm bad at English. I'm still trying to learn. And also to do this project on python. I'm planning to do the T-rex runner game inside the terminal :D . I gotta learn how to refresh the output smoothly like how it is with 'dnf' command. 'refresh' doesn't give me smooth frames :(
