python初学者，这里想调用work_cell中的cell1，怎么调用

from datetime import *
from openpyxl import load_workbook
import window

# t = datetime.strptime(str(window.day()),'%Y-%m-%d')

t = datetime.strptime(input('开始时间：'),'%Y-%m-%d')

# 读取工作日志文件
f = open('C:\\Users\\Administrator\\Desktop\\工作日志.docx','w')

# 获取每日报表内容
d = t.day
m = t.month
s = str(t.year)+'-'+str(t.month)+'-'+str(t.day)
file_path = "D:\周继彪\法国兰斐\报表数据统计\每日报表\\2021法国兰斐综合报表（勿动）.xlsx"
wb = load_workbook(file_path,data_only=True)
sheets = wb.worksheets
sheet1 = sheets[m*2-2]
sheet2 = sheets[m*2-1]

# 获取对应单元格的值

    cell1 = sheet1.cell((d + 1)*12+1,4).value
    cell2 = sheet1.cell((d + 2)*12+1,3).value

# 输出工作日志内容
def main():
    work()
    work_cell()



if __name__ == '__main__':
    main()

retun 啊，按下标取

def aa():
    a = 1
    b = 2
    c = 3
    return a, b, c


a = aa()
print(a[1])
