python3 时间模块 random模块之两个小练习

话不多说，一个是算时间的，还有一个是生成验证码的

 import time
 start_time = "2016-9-1 7:00:00"
 handel = time.mktime(time.strptime(start_time, "%Y-%m-%d %H:%M:%S"))
 now = time.time()
 now_strtime = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(now))
 print(now_strtime)
 dis_time = now - handel
 struc_time = time.localtime(dis_time)
 print("我已经来这儿\033[41;1m%d年，%d月，%d日,%d小时，%d分钟，%d秒了！\033[0m,好快呀" %
       (struc_time.tm_year-1970, struc_time.tm_mon-1, struc_time.tm_mday-1,
        struc_time.tm_hour, struc_time.tm_min, struc_time.tm_sec))

验证码：
