我试图在两个文件之间进行比较filecmp，问题是结果始终是"No, the files are NOT the same"，这意味着False 即使文件是相同的。我正在向两个不同的文件写入相同的内容。首先我写入文件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我的目标是如果文件相等 - 停止脚本。如果不是，它将重写revision_2.txt然后发送邮件，（我已经编写了邮件代码）。

尝试将shallow设置为false（默认为True），即
if filecmp.cmp('revision_1.txt', 'revision_2.txt', shallow=False):从文档中：如果为 true，则具有相同 os.stat() 签名的文件被视为相等。否则，将比较文件的内容。

如何忽略 message-id （我只需要修订值）？
查看脚本输出：不等于修订版：fpc1-1603878922-228

您对文件的使用不寻常：
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
