Python熊貓錯誤

-5

首先，大家好。我目前正在進行一個項目，我的主要目標是從csv文件中獲取一些地址，計算這些地址與可信數據庫的相似百分比並返回該值。我有一個代碼正在工作，但是當我嘗試計算相似的速率時，我收到「write to csv」函數的錯誤。代碼只運行一行，然後崩潰。錯誤開始發生在第30行之後。預先感謝您的幫助，祝您有美好的一天。Python熊貓錯誤

第29行是一條評論......我不認爲錯誤在那裏 – depperm

看來，錯誤的to_csv方法調用之前發生：cp4沒有關鍵1。

你讀過回溯嗎？它明確指出，問題是出在線路74：

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

你試圖訪問cp4[1]，它看起來像CP4就像對象字典，沒有關鍵1。無論如何，這有點奇怪。當您在cp4上迭代時，您正在嘗試訪問cp4[1]。請考慮一下。
