But here's a case where it seems I do need the

if msvcrt.kbhit() line

=========================
#!/usr/bin/env python
#coding=utf-8
import time
import msvcrt
timeNow = time.time()
oldTimeNow = timeNow
while True:
     if msvcrt.kbhit():
         key = msvcrt.getch()
         if key == 'h':
             print 'Hello'
         if key == 'b':
             print 'Bye'
         if key == '\r': # Enter key
             break
     timeNow = time.time()
     if timeNow - oldTimeNow > 5:
         print "5 seconds passed"
         oldTimeNow = timeNow
==========================

Without that line:
==========================
#!/usr/bin/env python
#coding=utf-8
import time
import msvcrt
timeNow = time.time()
oldTimeNow = timeNow
while True:
     #if msvcrt.kbhit():
     key = msvcrt.getch()
     if key == 'h':
         print 'Hello'
     if key == 'b':
         print 'Bye'
     if key == '\r': # Enter key
         break
     timeNow = time.time()
     if timeNow - oldTimeNow > 5:
         print "5 seconds passed"
         oldTimeNow = timeNow
============================

Without that line the "5 seconds passed" report is printed ONLY after 
a "b" or an "h", not what I want.
