input=''
whileTrue:
ifmsvcrt.kbhit():
chr=msvcrt.getche()
iford(chr)==13:#enter_key
break
eliford(chr)>=32:#space_char
input+=chr
iflen(input)==0and(time.time()-start_time)>timeout:
break
print''#neededtomovetonextline
iflen(input)>0:
returninput
else:
returndefault
readInput("TEst1",10)
'''
###catchkeyboardinput,ifkey==ESC,stop
importsys,time,msvcrt
defreadKeyBoardInput(timeout=5):
start_time=time.time()
sys.stdout.write("Ifyouwanttostoptestprocess,pleaseclickESCbutton");
