在本文中，我们将讨论 DateTime 模块中的 weekday() 函数。 weekday() 函数用于根据给定的 DateTime 获取周数。它将返回 0-6 范围内的数字表示意义0Monday1Tuesday2Wednesday3Thursday4Friday5Saturday6Sunday

它将以“(YYYY, MM, DD, HH, MM, SS)”的格式将输入作为DateTime，其中，

YYYY 代表年份MM 代表月DD 代表日期HH 代表小时MM代表分钟SS 代表秒

我们首先需要导入 DateTime 模块并创建一个 DateTime，现在使用 weekday() 函数我们将获得特定 DateTime 的工作日。

用法:

datetime(YYYY,MM,DD, HH,MM,SS).weekday()

我们还可以使用以下语法从 DateTime 中提取日期：

用法:

datetime(YYYY,MM,DD, HH,MM,SS).date()

示例:Python程序来创建DateTime并显示DateTime和日期

Python3 # importing datetime class from datetime import datetime # create datetime x = datetime(2021, 8, 8, 12, 5, 6) # display print("Datetime is:", x) # get the date print("Date is:", x.date())

输出：

Datetime is:2021-08-08 12:05:06

Date is:2021-08-08

例：用于获取给定日期时间的工作日的 Python 程序

Python3 # importing datetime class from datetime import datetime # create datetime x = datetime(2021, 8, 8, 12, 5, 6) # display print("Datetime is:", x) # get the weekday print("weekday is:", x.weekday()) # create datetime x = datetime(2021, 9, 10, 12, 5, 6) # display print("Datetime is:", x) # get the weekday print("weekday is:", x.weekday()) # create datetime x = datetime(2020, 1, 8, 12, 5, 6) # display print("Datetime is:", x) # get the weekday print("weekday is:", x.weekday())

输出：

Datetime is:2021-08-08 12:05:06

weekday is:6

Datetime is:2021-09-10 12:05:06

weekday is:4

Datetime is:2020-01-08 12:05:06

weekday is:2

范例3：获取工作日名称的Python程序

Python3 # create a list of weekdays from datetime import datetime days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"] # importing datetime class # create datetime x = datetime(2021, 8, 8, 12, 5, 6) # display print("Datetime is:", x) # get the weekday name using index print("weekday is:", days[x.weekday()]) # create datetime x = datetime(2021, 9, 10, 12, 5, 6) # display print("Datetime is:", x) # get the weekday name using index print("weekday is:", days[x.weekday()]) # create datetime using index x = datetime(2020, 1, 8, 12, 5, 6) # display print("Datetime is:", x) # get the weekday name using index print("weekday is:", days[x.weekday()])

输出：

Datetime is:2021-08-08 12:05:06

weekday is:Sunday

Datetime is:2021-09-10 12:05:06

weekday is:Friday

Datetime is:2020-01-08 12:05:06

weekday is:Wednesday
