如何获取下个月的 1 号和最后一天

借鉴一下

import datetime
import calendar


def get_date_of_next_month():
    """
    获取下月开始结束日期
    :return: str，date tuple
    """
    today = datetime.date.today()
    year = today.year
    month = today.month
    if month == 12:
        year += 1
        month = 1
    else:
        month += 1

    begin_of_next_month = datetime.date(year, month, 1).strftime('%Y-%m-%d')
    _, day = calendar.monthrange(year, month)
    end_of_next_month = datetime.date(year, month, day).strftime('%Y-%m-%d')
    return begin_of_next_month, end_of_next_month
	```
