# 原代码
def find_money(file_path, account, b_account, money, type_word, time):
    file = pd.read_excel(file_path)
    with open('money.csv', 'a', newline='', encoding='utf-8') as f:
        for i in file.index:
            ···省略中间的代码···

            if ···省略中间的代码···:
                file.loc[[i]].to_csv(f,index=False)
                find_same(file, account, b_account, money, type_word, time)


def find_same(file, account, b_account, money, type_word, time):
    ···省略中间的代码···
    with open('money.csv', 'a', newline='', encoding='utf-8') as f:
        for i in file.index:
            ···省略中间的代码···

            if ···省略中间的代码···
                file.loc[[i]].to_csv(f,header=False, index=False)

在处理数据的时候，遇到了不管怎样修改都无法将数据追加写入到最后一行的位置上，在询问各大AI大模型和翻阅Google无果后，找到了解决方法
即：在with open()之后，退出with open()再运行接下来的操作，方可解决

# 修改之后的代码

    file = pd.read_excel(file_path)
    for i in file.index:
        ···省略中间的代码···

        if ···省略中间的代码···:
        	with open('money.csv', 'a', newline='', encoding='utf-8') as f:	
            	file.loc[[i]].to_csv(f,index=False)
            find_same(file, account, b_account, money, type_word, time)


def find_same(file, account, b_account, money, type_word, time):
    ···省略中间的代码···
    for i in file.index:

            if ···省略中间的代码···
            	with open('money.csv', 'a', newline='', encoding='utf-8') as f:
