我目前正在使用 python-docx 庫（版本 0.8.1.1）在 PyCharm（社區版 2021.3.3）上撰寫一些 python（版本 3.10.4）代碼，它允許檢查 Word 檔案中使用的紙張是否為 A4。該檔案包含通過 2x Section Break（下一頁）創建的三個部分。
代碼（如下所示）的目的是根據檔案中各個部分的頁面寬度和頁面高度列印特定的陳述句。代碼僅部分功能來實作此目的。
當整個檔案不是 A4 時，應該列印“整個檔案不包含 A4 尺寸的紙張”。但它沒有這樣做，而是列印“第 1 部分不包含 A4 尺寸的紙張”。當第 1 節和第 2 節不是 A4 時（其中列印“第 1 節不包含 A4 尺寸的紙張。”），當第 1 節和第 3 節不是 A4 時（奇怪地列印“整個檔案沒有不包含 A4 尺寸的紙張。”）以及當第 2 節和第 3 節不是 A4 時（其中列印“第 2 節不包含 A4 尺寸的紙張。”）。
我想知道如何解決這些問題以確保代碼列印正確的陳述句。我相信問題可能出在 if-elif 塊中。但是，我在很大程度上未能找到問題的根源。
任何形式的幫助將不勝感激。如果對代碼有任何疑問，請詢問。

uj5u.com熱心網友回復：
請注意，這A4 != A3 != A4將評估為 True，因此您不是在檢查是否全部不是 A4，而是檢查第 1 節不是 a4 并且第 2 節與第 1 節不同，依此類推...
相反，您必須這樣做：
elif section1_pgheight != {10692130} and section2_pgheight != {10692130} and section3_pgheight != {10692130} and section1_pgwidth != {7560310} and section2_pgwidth != {7560310} and section3_pgwidth != {7560310}:
print("Whole document does not contain A4 size paper.")
另外，當您可以檢查是否相等時，我看不到使用集合的意義。此外，避免重復自己，更好的代碼是：
sections = [] #use a list to perserve order
# original loop was not doing anything so remove it
for section in WordFile.sections:
sections.append((section.height, section.width)) #add dimension tuple
def isA4(dimensions):
A4_WIDTH = 7560310 #avoid magic numbers
A4_HEIGHT = 10692130
height, width = dimensions #unpack dimesnsion tuple
# define helper which would remove a lot of the repetetive checking
return height == A4_HEIGHT and width == A4_WIDTH
# check if all sections are A4
sections_a4 = [*map(isA4, sections)]
if not any(sections_a4):
print("Whole Doc. not A4")
else:
# loop over section num and whether it is A4
for i, b in enumerate(sections_a4): # iterable (1, True) ...
if not b: #section is not A4
print(f"Section {i} is not A4!")
# you could break here if you want to only print once
