问题描述

为什么x ="None"而不是"500"? 我已经尝试了我所知道的一切，并在1个小时内寻找答案... 谢谢您的帮助！

Why does x = "None" instead of "500"? I have tried everything that I know and searched 1 hour for answer... Thank you for any help!

import openpyxl

wb = openpyxl.Workbook()
sheet = wb.active
sheet["A1"] = 200
sheet["A2"] = 300
sheet["A3"] = "=SUM(A1+A2)"

wb.save("writeFormula.xlsx")

wbFormulas = openpyxl.load_workbook("writeFormula.xlsx")
sheet = wbFormulas.active
print(sheet["A3"].value)

wbDataOnly = openpyxl.load_workbook("writeFormula.xlsx", data_only=True)
sheet = wbDataOnly.active
x = (sheet["A3"].value)
print(x) # None? Should print 500?
