需要从日期范围中获取月份

import datetime

def get_months_in_date_range(start_date, end_date):
    start_year = start_date.year
    end_year = end_date.year
    start_month = start_date.month
    end_month = end_date.month

    months = []

    for year in range(start_year, end_year + 1):
        if year == start_year and year == end_year:
            for month in range(start_month, end_month + 1):
                months.append(month)
        elif year == start_year:
            for month in range(start_month, 13):
                months.append(month)
        elif year == end_year:
            for month in range(1, end_month + 1):
                months.append(month)
        else:
            for month in range(1, 13):
                months.append(month)

    return months

# 示例用法
start_date = datetime.date(2022, 1, 15)
end_date = datetime.date(2023, 3, 20)
months = get_months_in_date_range(start_date, end_date)
print(months)
