Bash: Clearing the screen completely including prompt

I have a bash code that read input from a file.

for line in $(cat python.py); do
read input
echo $input;
echo "[$line]"
done

What i want is to read input in a complete clear terminal screen including the prompt like it does in VIM.

You can do:

while read line; do
   read input
   echo $input;
   echo "[$line]"
   clear
done < python.py

See clear at the end of the loop to clear the terminal.

Also no need of redundant cat since file can be read from stdin redirection.

Maybe you can clear the prompt by changing the environment variable PS1. Something like

OLDPS1=$PS1
PS1=
clear

should clear your screen and let you input whatever you want with no prompt at all. Restore the variable PS1 once finished with

PS1=$OLDPS1
