Python DateTime–time .用示例替换()方法
原文:https://www . geesforgeks . org/python-datetime-time-replace-method-with-example/
在本文中，我们将讨论 Python 中的 time.replace()方法。此方法用于操作模块日期时间的时间类对象。它用于用相同的值替换时间，除了那些由任何关键字参数赋予新值的参数。
语法:替换(年=自.年，月=自.月，日=自.日)
参数:
- 年:新年值(范围:1 < =年< = 9999)
- 月:新月值(范围:1 < =月< = 12)
- 日:新日值(范围:1 < =日< = 31)
返回:新的日期时间对象。
Python 程序获取时间并显示:
Python 3
# import time from datetime
from datetime import time
# create time
x = time(5,34,7,6789)
print("Time:", x)
输出:
Time: 05:34:07.006789
示例 1: Python 程序替换给定时间的小时
Python 3
# import time from datetime
from datetime import time
# create time
x = time(5, 34, 7, 6789)
print("Actual Time:", x)
# replace hour from 5 to 10
final = x.replace(hour = 10)
print("New time after changing the hour:", final)
输出:
Actual Time: 05:34:07.006789
New time after changing the hour: 10:34:07.006789
示例 2: Python 程序不时替换分钟
Python 3
# import time from datetime
from datetime import time
# create time
x = time(5, 34, 7, 6789)
print("Actual Time:", x)
# replace minute from 34 to 12
final = x.replace(minute = 12)
print("New time after changing the minute:", final)
输出:
Actual Time: 05:34:07.006789
New time after changing the minute: 05:12:07.006789
示例 3:替换秒的 Python 代码
Python 3
# import time from datetime
from datetime import time
# create time
x = time(5,34,7,6789)
print("Actual Time:", x)
# replace second from 7 to 2
final = x.replace(second = 2)
print("New time after changing the second:", final)
输出:
Actual Time: 05:34:07.006789
New time after changing the second: 05:34:02.006789
示例 4:一次全部替换的 Python 程序
Python 3
# import time from datetime
from datetime import time
# create time
x = time(5,34,7,6789)
print("Actual Time:", x)
# replace hour from 5 to 10
# replace minute from 34 to 11
# replace second from 7 to 1
# replace milli second from 6789 to 1234
final = x.replace(hour = 10, minute = 11,
second = 1, microsecond = 1234)
print("New time :", final)
输出:
Actual Time: 05:34:07.006789
New time : 10:11:01.001234
