嘗試進行情緒分析,但是在試圖從csv文件中創建字典的方法中的代碼部分的行中面對索引錯誤,該文件具有從Twitter訪問的推文,有人可以幫助我嗎?
檢查輸入CSV是否為空行。
如果line
是一個空列表,那么'list index out of range'錯誤將在twitter_list_dict.append(line[0])
拋出,因此沒有第一個要引用的元素。 最有可能是罪魁禍首:一個或多個在CSV行是空的,這將導致csv.reader
返回一個空列表line
。
如果預期CSV中有空行,您可以通過添加檢查來跳過它們以確保該行不為空:
for line in twitterreader:
if line: # Check if line is non-empty
twitter_list_dict.append(line[0])
return twitter_list_dict
