使用openpyxl将数据写入Excel工作表不起作用

Question

使用openpyxl,我试图从Excel工作簿中读取数据并将数据写入同一个Excel工作簿.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Cell A1中获取值Sheet1并打印出来.然后,我尝试把一些值进入细胞A2和A3.这不起作用.

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"

我确信代码是正确的......这里出了什么问题？

Answer 1

我相信你缺少一个保存功能.尝试添加以下附加行.

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")

Answer 2

用它来写入一个值：

ws1.cell(row=1, column=1,value='Hey')

另一方面，以下将读取该值：

ws1.cell(row=1, column=1).value
