openpyxl 工作簿对象的深拷贝

Question

我想知道是否有一种方法可以创建使用

load_workbook

方法创建的工作簿对象的深层副本。

我想创建一个像这样的流程（该项目将位于 Jypter Notebook 中）：

  #Cell 1
  
  import openpyxl

  #Cell 2
  
  wb1 = load_workbook("c:\temp\"abc123.xlsm", keep_vba=True) #This file is large and takes several minutes to load
  
  #Cell 3
  
  wb2 = wb1 #This doesn't create a deep copy but I would like something that creates a deep copy
  
  #Cell 4
  
  #Changes to wb2 happen here e.g. sheets get deleted. I would like to go back and rerun cell 2 so that I can reuse the wb1 variable without needing to load the file again.

我尝试使用 IDE 对 xlsx 文件进行快速测试。 这会从原始工作表中生成两个新的 xlsx 文件，一个在单元格“B10”中包含新工作表“newsheet”，其中包含“hello”，另一个在单元格“E10”中包含新工作表“Sheet10”和“Hello There” .

from openpyxl import load_workbook
from io import BytesIO


file = 'foo.xlsx'

with open(file, "rb") as fh:
    wb_data = BytesIO(fh.read())
    wb1 = load_workbook(wb_data)
    wb2 = load_workbook(wb_data)

    wb1.create_sheet('newsheet')
    wb2.create_sheet('Sheet10')

    ws1 = wb1['newsheet']
    ws2 = wb2['Sheet10']

    ws1.cell(10, 2).value = "Hello"
    ws2.cell(10, 5).value = "Hello There"

    wb1.save('save1.xlsx')
    wb2.save('save2.xlsx')
