Python编程获取当前日期的所属周日期信息

Python编程获取当前日期的所属周日期信息
今天继续学习Python编程，偶然看到一篇博客关于日期的操作，于是参照一下编写了一个获取当前日期所属的周的所有日期信息。本人的环境是Pycharm+macOS，程序需要的模块是datetime日期模块calendar日历模块。源码如下：

#_*_coding:utf-8_*_
# 作者      ：liuxiaowei
# 创建时间   ：3/12/22 11:07 AM
# 文件      ：一周内的日期显示.py
# IDE      ：PyCharm


# 导入日期和日历模块
import datetime
import calendar
# 定义一个字典存储星期几和对应的索引
weekDict = {
   '0':'Monday', '1': 'Tuesday', '2': 'Wednesday', '3':'Thursday', '4': 'Friday', '5': 'Saturday', '6': 'Sunday'}
# 定义一个天数字典
dayDict = {
   '1':'1st', '2':'2nd', '3':'3nd', '4':'4th', '5':'5th', '6':'6th','7':'7th'}

# 定义一个显示本周所有日期的函数
def show_currentweek_info():
    # 获取当天的日期并赋值给weekday变量
    weekday = datetime.date.today()
    # 设定一个一天为基准的变量
    one_day = datetime.timedelta(days=1)
    # for 循环是为了显示当前的日期信息
    for i in range(7):
        # 判断当前日期对应的数字
        if weekday.weekday() == i:
            # 判断对应的日期是本周的第几天
            day_number = datetime.date.isoweekday(weekday)
            print(f'\nThe current date is：{weekday}  Today is {weekDict[str(i)][:3]}  It\'s the No.{dayDict[str(day_number)]} day of this week.\n')


    # 判断周一到周日的日期
    for i in range(7):

        while weekday.weekday() != i:
            # 判断当前日期在周一到周日之前还是之后，如果在周一-周日（包括周一，周日）之前那就一天一天加
            if weekday.weekday() <= i:
                weekday += one_day
                day_number = datetime.date.isoweekday(weekday)
                # 如果在周一-到周日之后（包括周一，周日）那就一天一天减
            elif weekday.weekday() > i:
                weekday -= one_day
                day_number = datetime.date.isoweekday(weekday)

        print(f'{weekday} is {weekDict[str(i)][:3]} It is the No.{dayDict[str(day_number)]} day of this week.')

    if __name__ == "__main__":
        show_currentweek_info()

        # 获取当前日期的年份
        year = datetime.date.today().year
        # 获取当前日期的月份
        month = datetime.date.today().month
        # 获取当月的日历
        cal = calendar.month(year, month);
        print(f"\nHere is the calendar of this month:");
        print(cal);

运行结果如下：

The current date is：2022-03-12  Today is Sat  It's the No.6th day of this week.

2022-03-07 is Mon It is the No.1st day of this week.
2022-03-08 is Tue It is the No.2nd day of this week.
2022-03-09 is Wed It is the No.3nd day of this week.
2022-03-10 is Thu It is the No.4th day of this week.
2022-03-11 is Fri It is the No.5th day of this week.
2022-03-12 is Sat It is the No.6th day of this week.
2022-03-13 is Sun It is the No.7th day of this week.

Here is the calendar of this month:
     March 2022
Mo Tu We Th Fr Sa Su
    1  2  3  4  5  6
 7  8  9 10 11 12 13
14 15 16 17 18 19 20
21 22 23 24 25 26 27
28 29 30 31
