在excel中输出颜色，无法在parcharm中实现

如下代码在parcharm中无法实现：
import pandas as pd
def low_score_red(ss):
color = ‘red’ if ss<60 else ‘green’
return f’color:{color}’

students = pd.read_excel(R’E:\025,026/Students.xlsx’)
students.style.apply(low_score_red, subset=[‘Test_1’, ‘Test_2’, ‘Test_3’])
students.to_excel(R’E:\025,026/Students1.xlsx’)
