Openpyxl将多个工作表保存在一个工作簿中

Question

我想分别阅读多个excel文件，并使用Openpyxl将它们保存在一个工作簿中，作为工作表保存，我不确定.save（）函数是否有任何属性：

df1_wb = load_workbook(path +'df1_.xlsx')
df1_ws = df1_wb.get_active_sheet()

df2_wb = load_workbook(path +'df2_.xlsx')
df2_ws = df2_wb.get_active_sheet()

df3_wb = load_workbook(path +'df3_.xlsx')
df3_ws = df3_wb.get_active_sheet()


wb.save(path+'master_file.xlsx') ??
