我正在将一个函数集成到python 2代码中，它显示了一个语法错误：函数参数处的语法无效

我正在将一个函数集成到python 2代码中，它显示了一个语法错误：函数参数处的语法无效

这里是函数

def remove_federal_email_records(df_inv_file: pd.DataFrame,
                                 email_column: str,
                                 usf_master_file: str) -> pd.DataFrame:
    '''
    Remove records based on Federal domain emails.
    Records will be filtered using the US Federal e-mail master file.
    :param df_inv_file: A dataframe containing invite file data. It will be
    filtered using this function.
    :param column_name: The column which contains the email address.
    :param usf_master_file: The location of a .CSV file containing data with
    the US federal email domains in the first column.
    :returns: A pandas dataframe containing only the records with the approved
     countries.
    '''

这里是错误信息

感谢阅读

看起来您正在python 2中使用python 3类型的注释。请看这里：谢谢您的帮助，但由于我正在尝试将python 3 def复制到python 2中，现在我收到了以下错误lol“”’信息：OfferingProcessInvite:>>开始固定值函数信息：OfferingProcessInvite:>>开始固定值函数信息：OfferingProcessInvite:>>>启动单独的\u记录函数错误：\u\u主\u:'module'对象没有属性'dataframe''
