‘property’ object has no attribute ‘append’问题

如下，报错显示不可以在tmp_sh中使用append，但是我所看的教程当中这样是可行的……

from openpyxl import load_workbook,Workbook
wb = load_workbook('./raw_data/Chinese_score.xlsx')
sh = wb.active

title = []
for i,row in enumerate(sh.rows):
    tmp_list = []
    for cell in row:
        tmp_list.append(cell.value)
    if i<=1:
        title.append(tmp_list)
    else:
        tmp_wb = Workbook
        tmp_sh = tmp_wb.active
        tmp_sh.append(title)
        tmp_sh.append(tmp_list)
        tmp_wb.save(f'./raw_data/Chinese_score工资条/{i-1}_{tmp_list[0]}.xlsx')

这边是报错信息：

Traceback (most recent call last):
  File "c:\Users\Allen\Desktop\-\2021暑假\python编程\__\工资条练习.py", line 15, in <module>
    tmp_sh.append(title)
AttributeError: 'property' object has no attribute 'append'
PS C:\Users\Allen\Desktop\-\2021暑假\python编程\__> 

而在以下程序中，如下，这里的nsh是可以使用append的？

from openpyxl import load_workbook
wb1 = load_workbook('./raw_data/test_score_5.xlsx')
wb2 = load_workbook('./raw_data/test_score_11.xlsx')
sh1 = wb1.active
sh2 = wb2.active

from openpyxl import Workbook
nwb = Workbook()
nsh = nwb.active

for row in sh1.rows:
    tmp_list = []
    for cell in row:
        tmp_list.append(cell.value)
    nsh.append(tmp_list)

for row in sh2.rows:
    tmp_list = []
    for cell in row:
        tmp_list.append(cell.value)
    nsh.append(tmp_list)

nwb.save('./raw_data/test_score_together.xlsx')

这是为什么呢？该如何修改？
谢谢～

上面的第13行
试一下在Workbook后加括号
