I have seen this question asked a few times but have not seen a
clear answer...
I have a python script that prompts the user for input from stdin via a
menu. I want to process that input when the user types in two characters
and not have to have the user press <CR>. As a comparison, in the bash
shell one can use (read -n 2 -p "-->" CHOICE; case $CHOICE in...). Works
great and is very
straightforward. I have searched the python library and have not found
an answer to this simply task. raw_input(n) won't do it. I have looked
at the curses stuff but that is a bit overkill for what I need. I have
tried a while statement reading in characters from sys.stdin but no luck
there either. I am looking for an efficient way to do this simple task.
Here is the bash code I want to do in python. I am only looking for help
with the read of stdin portions, not the case statement:
while [ "$1" == "" ]; do
(echo " ---------")
(echo " Functions")
(echo " ---------")
(echo " option")
(echo " ------ ---- Scanning ----------")
(echo " ss Scan the System, Run the scan tool.")
(echo " rs Result of Scan, Show the result of the last
scan.")
read -e -n 2 -p "-->" CHOICE
case "$CHOICE" in
## scanning
"ss" | "SS" )
(echo "Scanning the system may take a very long time. Do you
wish to proceed?")
read -e -n 1 -p "[y/n]-->" INPUT
if [ "$INPUT" == "y" ]; then
sh scan -s
cd - &>/dev/null
else
(echo)
(echo "Scan aborted.")
fi
;;
... rest of case statement
esac
done
