如何将空表添加到已经使用pandas创build的“excel”文件中

我有数据，我补充说，以Excel

df.groupby('id').apply(lambda g: g.to_excel(g.name + '.xlsx', u'Смартфоны кратко')) 

接下来，我添加数据sheet到这些文件

 df_upd.groupby('id').apply(lambda x: add_xlsx_sheet(x, u'Смартфоны полно', path='{}.xlsx'.format(x.name))) 

但是，我怎样才能将空的sheet3添加到这些文件？ df_upd看起来像

和add_xlsx_sheet是

 def add_xlsx_sheet(df, sheet_name=u'Смартфоны кратко', index=True, digits=2, path=None): book = load_workbook(path) writer = pd.ExcelWriter(path, engine='openpyxl') writer.book = book writer.sheets = dict((ws.title, ws) for ws in book.worksheets) if sheet_name in list(writer.sheets.keys()): sh = book.get_sheet_by_name(sheet_name) book.remove_sheet(sh) df.to_excel(excel_writer=writer, sheet_name=sheet_name, startrow=0, startcol=0, float_format='%.{}f'.format(digits), index=index) writer.save() 

Answer 1

您可以使用workbook.add_worksheet() ：

 def add_xlsx_sheet(df, sheet_name=u'Смартфоны кратко', index=True, digits=2, path=None): book = load_workbook(path) writer = pd.ExcelWriter(path, engine='openpyxl') writer.book = book writer.sheets = dict((ws.title, ws) for ws in book.worksheets) if sheet_name in list(writer.sheets.keys()): sh = book.get_sheet_by_name(sheet_name) book.remove_sheet(sh) df.to_excel(excel_writer=writer, sheet_name=sheet_name, startrow=0, startcol=0, float_format='%.{}f'.format(digits), index=index) workbook = writer.book worksheet = workbook.add_worksheet() writer.save()
