python - 使用 openpyxl 将数据写入 Excel-Sheet 不起作用

Question

使用 openpyxl，我试图从 Excel-Workbook 读取数据并将数据写入同一个 Excel-Workbook。从 Excel-Workbook 获取数据工作正常，但将数据写入 Excel-Workbook 不起作用。使用下面的代码，我从 Sheet1 中的 Cell A1 获取值并打印它。然后我尝试将一些值放入单元格 A2 和 A3 中。这是行不通的。

from openpyxl import Workbook
from openpyxl import load_workbook


wb = load_workbook("testexcel.xlsm")
ws1 = wb.get_sheet_by_name("Sheet1")

#This works:
print ws1.cell(row=1, column=1).value 

#This doesn't work:
ws1['A2'] = "SomeValue1"

#This doesn't work either:
ws1.cell(row=3, column=1).value = "SomeValue2"

我确定代码是正确的...这里出了什么问题？

我相信您缺少保存功能。尝试在下面添加附加行。

from openpyxl import Workbook
from openpyxl import load_workbook


wb = load_workbook("testexcel.xlsm")
ws1 = wb.get_sheet_by_name("Sheet1")

#This works:
print ws1.cell(row=1, column=1).value 

#This doesn't work:
ws1['A2'] = "SomeValue1"

#This doesn't work either:
ws1.cell(row=3, column=1).value = "SomeValue2"

#Add this line
wb.save("testexcel.xlsm")
