Python pywin32（win32com.client）在打開（）后准備好Microsoft Word文檔之前響應錯誤表

Question

我發現從 MS Word 文檔中讀取的表 python 是錯誤的，但如果等待一段時間可能是正確的，所以我做了這個實驗來調查問題：

1. open a Word .docx document, it has total 26 tables.
2. Repeatedly print and see how many tables in this document? 
   Surprisingly this number is changing!
3. So the question is: how to know if the document is ready after .Open() ?

這是實驗的代碼：

import time 
import win32com.client
word_app = win32com.client.Dispatch("Word.Application")

doc = word_app.Documents.Open(FileName = pathname, ConfirmConversions = False,NoEncodingDialog = True,Revert = True)
for i in range(40):
    print("%d:%d " % (i, doc.tables.count), end="")
    time.sleep(0.1)
doc.Close()

結果：

 0:24 1:24 2:24... there were 24 tables at first, wrong! should be 26 
12:25 13:25    ... then it became 25
26:26 27:26 28:26 ... then become 26 which is finally correct

Answer 1

Open 方法一完成，文檔就准備好了。 Word 對象模型不提供任何屬性或方法來檢查文檔是否已加載和初始化，就像在 HTML 網頁（Web 瀏覽器）的情況下一樣。

Answer 2

這是我的解決方法

import time, docx, win32com.client
word_app = win32com.client.Dispatch("Word.Application")

doc_lib = docx.Document(pathname)
doc_com = word_app.Documents.Open(FileName = pathname)
while len(doc_lib.tables) != doc_com.tables.count:
    # need to wait probably a minute for doc_com to be really ready
    time.sleep(1)
