How do I delete letters after I write them to make room for the next sentence?

Question

I want to write something, for instance:

print("Hello.")

Then, I want to erase it to make room for a new word/phrase/sentence, such as:

print("Hi")

How can I do this?

Answer 1

The typical solution is not to delete your previous lines, but print the instruction in the next line and read from there so the user can see the (input/output) message history on the screen.

Update

If you really want to do what you just asked, you can clear the screen and then print to the empty screen again.

Have a look at this: https://www.geeksforgeeks.org/clear-screen-python/ (I'm assuming you're doing Python.)
