我試圖在兩個文件之間進行比較filecmp，問題是結果始終是"No, the files are NOT the same"，這意味著False 即使文件是相同的。我正在向兩個不同的文件寫入相同的內容。首先我寫入文件revision_1.txt：original_stdout = sys.stdoutwith open('revision_1.txt', 'w') as rev1: sys.stdout = rev1 print(revision) # revision is output from command i took beforesys.stdout = original_stdoutif filecmp.cmp('revision_1.txt', 'revision_2.txt'): # revision_2.txt is file I c print("Both the files are same")else: # Do whatever you want if the files are NOT the same print("No, the files are NOT the same")original_stdout = sys.stdoutwith open('revision_2.txt', 'w') as rev2: sys.stdout = rev2 print(revision) # revision is output from command i took beforesys.stdout = original_stdout我的目標是如果文件相等 - 停止腳本。如果不是，它將重寫revision_2.txt然后發送郵件，（我已經編寫了郵件代碼）。

嘗試將shallow設置為false（默認為True），即
if filecmp.cmp('revision_1.txt', 'revision_2.txt', shallow=False):從文檔中：如果為 true，則具有相同 os.stat() 簽名的文件被視為相等。否則，將比較文件的內容。

如何忽略 message-id （我只需要修訂值）？

您對文件的使用不尋常：
import filecmp
revision = "08/15"
with open('revision_1.txt', 'w') as rev1:
rev1.write(revision)
with open('revision_2.txt', 'w') as rev2:
rev2.write(revision)
with open('revision_3.txt', 'w') as rev3:
rev3.write(revision + "-42")
# should compare equal
if filecmp.cmp('revision_1.txt', 'revision_2.txt'):
print("Identical")
else:
print("No, the files are NOT the same")
# should NOT compare equal
if filecmp.cmp('revision_1.txt', 'revision_3.txt'):
print("Identical")
else:
print("No, the files are NOT the same")
印刷
Identical
No, the files are NOT the same
