Question

总睡眠时间应为60秒，并且每次检查的间隔应为5秒。我应该如何使用count变量来跟踪总执行次数


def test(a):
    count=0
    while True:
        if a < 10:
            print("ok")
            return True
        count = count+1
        time.sleep(5)

        if(count == 12):
            return False

print(test(a=40))

while循环应在60秒后停止执行并返回false，每个检查间隔为5秒。我感到困惑，我应该在time.sleep（5）之前还是time.sleep（5）之后增加计数。看到time.sleep被执行了12次并且等待了60秒并返回false，该怎么办？

Answer 1

import time
def test(a):
    count=0
    while True:
        if a < 10:
            print("ok")
            return True
        count = count+1
        time.sleep(5)

        if(count == 12):
            return False

print ("Start : %s" % time.ctime())
print(test(a=40))
print ("End : %s" % time.ctime())[enter image description here][1]

Answer 2

您可以使用time.time()

import time
max_time = 60

start_time = time.time()  # remember when we started


    def test(a):
    count=0
    while (time.time() - start_time) < max_time:
        if a < 10:
            print("ok")


print(test(a=40))

在特定时间段内运行Python函数
