Python熊猫错误

-5

首先，大家好。我目前正在进行一个项目，我的主要目标是从csv文件中获取一些地址，计算这些地址与可信数据库的相似百分比并返回该值。我有一个代码正在工作，但是当我尝试计算相似的速率时，我收到“write to csv”函数的错误。代码只运行一行，然后崩溃。错误开始发生在第30行之后。预先感谢您的帮助，祝您有美好的一天。Python熊猫错误

第29行是一条评论......我不认为错误在那里 – depperm

看来，错误的to_csv方法调用之前发生：cp4没有关键1。

你读过回溯吗？它明确指出，问题是出在线路74：

File ".\Teste.py", line 74, in <module> 
    cp4[1].to_csv('AI.csv')

你试图访问cp4[1]，它看起来像CP4就像对象字典，没有关键1。无论如何，这有点奇怪。当您在cp4上迭代时，您正在尝试访问cp4[1]。请考虑一下。
