python 获取整点时间戳,半整点时间戳 ，同时将时间戳转换成 日期时间

import time, datetime
def gettime():
    for x in range(24):
        a = datetime.datetime.now().strftime("%Y-%m-%d") + " %2d:00:00" % x
        timeArray = time.strptime(a, "%Y-%m-%d %H:%M:%S")
        timeStamp = int(time.mktime(timeArray))
        print(timeStamp)
if __name__ == "__main__":
    gettime()
