如何将MM-dd-yyyy字符串转换为(满月)-yyyy

import datetime

def convert_date_string(date_string):
    # 将字符串转换为datetime对象
    date_obj = datetime.datetime.strptime(date_string, "%m-%d-%Y")
    
    # 定义满月名称对应关系
    month_names = {
        1: "一月满月",
        2: "二月满月",
        3: "三月满月",
        4: "四月满月",
        5: "五月满月",
        6: "六月满月",
        7: "七月满月",
        8: "八月满月",
        9: "九月满月",
        10: "十月满月",
        11: "十一月满月",
        12: "十二月满月"
    }
    
    # 获取月份和年份
    month = date_obj.month
    year = date_obj.year
    
    # 根据月份获取对应的满月名称
    full_moon_name = month_names[month]
    
    # 拼接满月名称和年份
    result = f"{full_moon_name}-{year}"
    
    return result

date_string = "03-17-2023"
converted_date = convert_date_string(date_string)
print(converted_date)  # 输出：三月满月-2023
