Python：将数据帧导出到CSV文件时出错

尝试将pandas数据帧导出到csv时出现以下错误

    Traceback (most recent call last):
    File "C:/Users/riley/PycharmProjects/EarlyPaidLoanReport/EarlyPaidOff.py", line 91, in <module>
    LastTransactionDate.to_csv(LastTransactionDate, 'example.csv')
    File "C:\Users\riley\Anaconda3\lib\site-packages\pandas\core\frame.py", line 1344, in to_csv
    formatter.save()
    File "C:\Users\riley\Anaconda3\lib\site-packages\pandas\formats\format.py", line 1526, in save
    compression=self.compression)
    File "C:\Users\riley\Anaconda3\lib\site-packages\pandas\io\common.py", line 424, in _get_handle
    f = open(path, mode, errors='replace')
    TypeError: invalid file:        AutoNumber                       LoanAgreementID  \

你的语法错了。除非我遗漏了什么，否则就这么做：

---

LastTransactionDate.to_csv（'example.csv'）

参数则相反。首先是文件名…

LastTransactionDate.to_csv（'example.csv'）

。为什么要复制您的

DF

？

LastTransactionDate.to_csv(LastTransactionDate, 'example.csv')
