Python给定开始日期年月与结束日期年月—生成每月的第一天与最后一天

背景

其实，关于日期的相关知识点，已经被我写了好多了，目前在办公中已经很少再遇到关于日期的知识点了，今天的需求：给定开始时间年月与结束时间年月—生成每月的第一天与最后一天

库的话，是内置库【datetime 】，所以无需安装

代码

from datetime import datetime, timedelta

start_date = datetime(2022, 11, 1)
end_date = datetime(2023, 10, 31)

current_date = start_date
while current_date <= end_date:
    first_day = current_date.replace(day=1)
    last_day = (current_date.replace(day=1) + timedelta(days=32)).replace(day=1) - timedelta(days=1)

    # print(f"Month: {current_date.strftime('%B %Y')}")
    print(f"First day: {
      
      first_day.strftime('%Y-%m-%d')}",end=' ')
    print(f"Last day: {
      
      last_day.strftime('%Y-%m-%d')}")


    current_date += timedelta(days=32)

输出

First day: 2022-11-01 Last day: 2022-11-30
First day: 2022-12-01 Last day: 2022-12-31
First day: 2023-01-01 Last day: 2023-01-31
First day: 2023-02-01 Last day: 2023-02-28
First day: 2023-03-01 Last day: 2023-03-31
First day: 2023-04-01 Last day: 2023-04-30
First day: 2023-05-01 Last day: 2023-05-31
First day: 2023-06-01 Last day: 2023-06-30
First day: 2023-07-01 Last day: 2023-07-31
First day: 2023-08-01 Last day: 2023-08-31
First day: 2023-09-01 Last day: 2023-09-30
First day: 2023-10-01 Last day: 2023-10-31
