python关于excel多个sheet的导入导出方式

import pandas as pd
df = pd.read_excel('test.xlsx', sheet_name = None) # 导入一个excel中的所有sheet
df

chinese = df.get('语文成绩')
math = df.get('数学成绩')
math

#  将多个dataframe导入到同一个excel
writer = pd.ExcelWriter('score.xlsx',engine='xlsxwriter')
chinese.to_excel(writer, sheet_name = 'chinese', index = False)
math.to_excel(writer, sheet_name = 'math', index = False)
writer.save() # 此语句不可少，否则本地文件未保存

from openpyxl import Workbook
from openpyxl import load_workbook
from openpyxl.writer.excel import ExcelWriter
# 导入字体、边框、颜色以及对齐方式相关库
from openpyxl.styles import Font, Border, Side, PatternFill, colors, Alignment
