python -- 解決If using all scalar values, you must pass an index問題

【問題描述】

在將dict轉為DataFrame時會報錯：If using all scalar values, you must pass an index

例如：

summary = pd.DataFrame({key:value for key,value in test.items()if key in index}) #查看匯總表情況

【解決辦法】

添加參數：index = [0]

summary = pd.DataFrame({key:value for key,value in test.items()if key in index},index = [0]) #查看匯總表情況
