python如何引入time
在Python中，我們可以使用time模塊來處理與時間相關(guān)的操作。time模塊提供了一些實用的函數(shù)，如獲取當(dāng)前時間、計算時間差、格式化時間等，要引入time模塊，只需在代碼中使用import關(guān)鍵字即可。

以下是一些常見的time模塊函數(shù)及其用法：
1、獲取當(dāng)前時間：
import time
current_time = time.time()
print("當(dāng)前時間戳：", current_time)
2、將時間戳轉(zhuǎn)換為可讀的時間格式：
import time
timestamp = time.time()
readable_time = time.strftime("%Y%m%d %H:%M:%S", time.localtime(timestamp))
print("可讀時間：", readable_time)
3、計算兩個時間戳之間的差值：
import time
timestamp1 = time.time()
執(zhí)行一些操作...
timestamp2 = time.time()
time_difference = timestamp2 timestamp1
print("時間差（秒）：", time_difference)
4、休眠一段時間：
import time
print("開始休眠")
time.sleep(5) # 休眠5秒
print("休眠結(jié)束")
5、格式化時間：
import time
from datetime import datetime, timedelta
now = datetime.now()
yesterday = now timedelta(days=1)
tomorrow = now + timedelta(days=1)
formatted_now = now.strftime("%Y%m%d %H:%M:%S")
formatted_yesterday = yesterday.strftime("%Y%m%d %H:%M:%S")
formatted_tomorrow = tomorrow.strftime("%Y%m%d %H:%M:%S")
print("今天的日期和時間：", formatted_now)
print("昨天的日期和時間：", formatted_yesterday)
print("明天的日期和時間：", formatted_tomorrow)
6、獲取當(dāng)前日期和星期幾：
import time
from datetime import date, timedelta, weekday
now = date.today()
weekday_number = now.weekday() + 1 # 星期一為0，星期二為1，以此類推...星期天為6
weekday_name = ["星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期天"][weekday_number 1]
print("今天的日期：", now)
print("今天是星期：", weekday_name)
7、獲取當(dāng)前年份、月份和日期：
import time
from datetime import date, month, year, day, weekday, timedelta,
tzinfo, timezone, DSTInfo, localize, mktime, asctime, ctime, gmtime,
mktime_ns, asctime_ns, ctime_ns, gmtime_ns, strftime, strptime,

dst, fromordinal, isocalendar, isoweekday, weekday, replace,
