time-时间模块

# time模块
import time

# print(123)

# 自定义延迟
# old_time = time.time()

# print(time.gmtime())

# import calendar
# # 判断闰年
# print(calendar.isleap(2000))
# # 查看某年某月日历
# print(calendar.month(2008, 8))
# # 查看某年某月起始星期与当月天数
# print(calendar.monthrange(2019, 4))
# # 查看某年某月某日是星期几
# print(calendar.weekday(2019, 4, 1))

import datetime
# 当前时间 ***
res = datetime.datetime.now()
print(res, type(res))

# 可以完成时间的运算
print(datetime.datetime.now() + datetime.timedelta(hours=1))

# 修改时间
new_time = time_obj.replace(year=2000, day=1)

# 格式化时间戳: 2019-04-27
