Answer 3

Slick Thanks for your answer! 😊

what is mean '\033[F' ?

is it same as '\r' ?
from where I can learn codes like this ?

Answer 4

Its a character that brings the cursor up to the beggining of the previous line.

i think '\r' is for carridge return. Think about a type writer when you get to the end of a line on a piece of paper. When you get to the end, you shove the carridge right back to the begginning of the line.

"\033[F" will not go to the beggining of the current line, but the beggining of the previous one thats right above it.

i found it by searching "print on previous line python"

Answer 5

My bad, the character should be "\033[A" not "\033[F" was doing some testing.

"\033[A" works just fine

Answer 6

Slick your code works same without using '\033[F'
then what's the case here ? 🤔
