How to read a single character from the user?

Question

Is there a way of reading one single character from the user input? For instance, they press one key at the terminal and it is returned (sort of like getch()).

Answer 1

This is NON-BLOCKING, reads a key and and stores it in keypress.key.

import Tkinter as tk


class Keypress:
    def __init__(self):
        self.root = tk.Tk()
        self.root.geometry('300x200')
        self.root.bind('', self.onKeyPress)

    def onKeyPress(self, event):
        self.key = event.char

    def __eq__(self, other):
        return self.key == other

    def __str__(self):
        return self.key

in your programm

keypress = Keypress()

while something:
   do something
   if keypress == 'c':
        break
   elif keypress == 'i': 
       print('info')
   else:
       print("i dont understand %s" % keypress)
