KeyError: 'num' Empty DataFrame Columns: [num, ratio] Index: [] *********counts2************ Series([], Name: count, dtype: int64)

以下是两种解决方法：
1. 解决AttributeError: ‘DataFrame’ object has no attribute ‘score’的错误

import pandas as pd
data = pd.read_excel(r"C:\Users\ASUS\Desktop\0012\data7.1.2.xlsx")
data['score'].describe()

2. 解决KeyError: 'num' Empty DataFrame Columns: [num, ratio] Index: [] *********counts2************ Series([], Name: count, dtype: int64)的问题

# 添加参数result_type='broadcast'
datas = df.apply(func, axis=1, result_type='broadcast')
