python时间戳获取、时间比较、时间推算

import datetime
import time
#print(datetime.datetime.now().strftime('%Y%m%d%H%M%S'))
#print('ctime---:%s'%time.ctime())
#print(datetime.datetime.now().strftime('%Y%m%d%H%M%S'))
curr_time=datetime.datetime.now().strftime('%Y%m%d%H%M')
print(str(curr_time))
print('ctime---:%s'%time.ctime())
now_time=datetime.datetime.now()
h=0.025#1.5minitues
m=h*60
exp_time=int(curr_time)+m
print("exp_time is: " + str(exp_time))
time.sleep(60)
after_time=datetime.datetime.now().strftime('%Y%m%d%H%M')
print(str(after_time))
if int(exp_time)>int(after_time):
    print("continue")
else:
    print("exit")

print(now_time.strftime("%Y-%m-%d %H:%M:%S"),(now_time+datetime.timedelta(minutes=+1/60)).strftime("%Y-%m-%d %H:%M:%S"))

print(now_time.strftime("%Y-%m-%d %H:%M:%S"),(now_time+datetime.timedelta(minutes=+1)).strftime("%Y-%m-%d %H:%M:%S"))

输出如下：
