datetime模块
import datetime # 获取当前时间
print(datetime.datetime.now()) # 2017-07-15 15:01:24.619000 # 格式化时间
print(datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S") )# 2017-07-15 15:01:35
print(datetime.datetime.now().strftime("%Y-%m-%d %H:%M")) # 2017-07-15 15:01
print(datetime.datetime.now().strftime("%Y%m%d")) #
对时间的加减用到的是datetime模块的timedelta方法
# 加一天
print((datetime.datetime.now()+datetime.timedelta(days=1)).strftime("%Y-%m-%d %H:%M:%S")) # 2017-07-16 15:12:42 # 加一小时
print((datetime.datetime.now()+datetime.timedelta(hours=1)).strftime("%Y-%m-%d %H:%M:%S")) # 2017-07-15 16:10:43 # 加一分钟
print((datetime.datetime.now()+datetime.timedelta(minutes=1)).strftime("%Y-%m-%d %H:%M:%S")) # 2017-07-15 15:12:56
