Python生成时间戳的各种实现方式

import time

timestamp = time.time()
print("当前时间戳：", timestamp)

当前时间戳： 1600000000.0

from datetime import datetime

now = datetime.now()
timestamp = now.timestamp()
print("当前时间戳：", timestamp)

当前时间戳： 1600000000.0

import calendar

time_tuple = (2020, 9, 13, 10, 30, 0)  # 年、月、日、时、分、秒
timestamp = calendar.timegm(time_tuple)
print("指定时间的时间戳：", timestamp)

指定时间的时间戳： 1600000000

import pytz
from datetime import datetime

utc_time = datetime(2020, 9, 13, 10, 30, 0, tzinfo=pytz.utc)
timestamp = (utc_time - datetime(1970, 1, 1, tzinfo=pytz.utc)).total_seconds()
print("UTC时间的时间戳：", timestamp)

UTC时间的时间戳： 1600000000.0

from datetime import datetime

time_str = "2020-09-13 10:30:00"
time_format = "%Y-%m-%d %H:%M:%S"
time_object = datetime.strptime(time_str, time_format)
timestamp = time_object.timestamp()
print("自定义时间格式的时间戳：", timestamp)

自定义时间格式的时间戳： 1600000000.0
