python -- 解决If using all scalar values, you must pass an index问题

Posted 2021-01-29 nxf_rabbit75

【问题描述】

在将dict转为DataFrame时会报错：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}) #查看汇总表情况

【解决办法】

添加参数：index = [0]

summary = pd.DataFrame({key:value for key,value in test.items()if key in index},index = [0]) #查看汇总表情况
