openpyxl

使用python修改excel文档，保留文档原有的样式风格

import numpy as np
import openpyxl as pd
from datetime import datetime, time
from  random import *

one = True
def read(sheet):
    global one
    for row in sheet:
        for cell in row:
            if isinstance(cell.value,time):
                cell.value = time(8,randint(28,40)) if one else time(17,randint(30,59))
                one = not one
        
        
table = pd.load_workbook('2022.4.xlsx')
sheet=table['2022.4']
read(sheet)
table.save('2022.4__1.xlsx')
