python time模块的使用

import time

# 当前时间戳
current_time = time.time()
print(current_time)
# 1567498447.616138

# 当前时间结构化对象--当地时间
current_time_obj = time.localtime()
print(current_time_obj)
# time.struct_time(tm_year=2019,tm_mon=9,tm_mday=3,tm_hour=16,tm_min=16,tm_sec=2,tm_wday=1,tm_yday=246,tm_isdst=0)

# 将结构化时间对象转化为时间戳
time_stamp = time.mktime(time.localtime())
print(time_stamp)
# 1567498880.0

# 将结构化时间对象转化为字符串时间
time_str = time.strftime('%Y-%m-%d %X', time.localtime())
print(time_str)
# 2019-09-03 16:29:29

# 将字符串时间转化为结构化时间对象
time_obj = time.strptime('2016-09-09 00:00:00', '%Y-%m-%d %X')
print(time_obj)
# time.struct_time(tm_year=2016,tm_mon=9,tm_mday=9,tm_hour=0,tm_min=0,tm_sec=0,tm_wday=4,tm_yday=253,tm_isdst=-1)

# 推迟运行时间,参数3秒
time.sleep(3)
