Question

我想在等待用户输入时执行一些操作：我在考虑：

var = raw_input("what are you thinking about")
while var == None:
   dosomethingwhilewaiting()
print "input is:", var

但raw_input在用户输入进入之前一直处于阻塞状态。有什么想法吗？

你可以使用线程。

import thread
import time

var = None
def get_input():
    global var
    var = raw_input("what are you thinking about")

thread.start_new_thread(get_input, ())

i = 0
while var == None:
    i += 0.1
    time.sleep(0.1)
print "input is:", var
print "it took you %d seconds to answer" % i

在raw_input为空时执行操作
