将值写入python中pandas表中的特定单元格

我有一个Excel工作表,它在某些单元格中已经有一些值。

对于前:-

        A      B      C      D

1 val1 val2 val3

2 valx valy

这是我尝试的代码。

import pandas as pd

from openpyxl import load_workbook

df2 = pd.DataFrame({'Data': [13, 24, 35, 46]})

book = load_workbook('b.xlsx')

writer = pd.ExcelWriter('b.xlsx', engine='openpyxl')

df2.to_excel(writer, "Sheet1", startcol=7,startrow=6)

writer.save()

但是,此代码将删除较旧的单元格值。

回答:

我无法使用熊猫来完成我在问题中提出的要求,但是可以使用来解决它Openpyxl

我将编写一些代码片段,以帮助实现所要求的内容。

import openpyxl

srcfile = openpyxl.load_workbook('docname.xlsx',read_only=False, keep_vba= True)#to open the excel sheet and if it has macros

sheetname = srcfile.get_sheet_by_name('sheetname')#get sheetname from the file

sheetname['B2']= str('write something') #write something in B2 cell of the supplied sheet

sheetname.cell(row=1,column=1).value = "something" #write to row 1,col 1 explicitly, this type of writing is useful to write something in loops

srcfile.save('newfile.xlsm')#save it as a new file, the original file is untouched and here I am saving it as xlsm(m here denotes macros).
