Python用字符串检查文件内容

Question

Hello! I have the following script:

import os
import stat

curDir = os.getcwd()

autorun_signature = [ "[Autorun]",
                      "Open=regsvr.exe",
                      "Shellexecute=regsvr.exe",
                      "Shell\Open\command=regsvr.exe",
                      "Shell=Open" ]

content = []

def read_signature(file_path):
    try:
        with open(file_path) as data:
            for i in range(0,5):
                content.append(data.readline())
    except IOError as err:
        print("File Error: "+   str(err))

read_signature(os.getcwd()+'/'+'autorun.inf')

if(content==autorun_signature):
    print("Equal content")
else:
    print("Not equal")

It prints not equal, then I tried this method:

import os
import stat

curDir = os.getcwd()

autorun_signature =  "[Autorun]\nOpen=regsvr.exe\nShellexecute=regsvr.exe\nShell\Open\command=regsvr.exe\nShell=Open"

content = ""

def read_signature(file_path):
    try:
        with open(file_path) as data:
            content = data.read()
    except IOError as err:
        print("File Error: "+   str(err))

read_signature(os.getcwd()+'/'+'autorun.inf')

if(content==autorun_signature):
    print("Equal content")
else:
    print("Not equal")

It also print not equal! I want to store the content of autorun.inf file in script and every time i find such file I want to check its content if it is or not, I could not do, can anyone help me? the content of autorun.inf:

[Autorun]
Open=regsvr.exe
Shellexecute=regsvr.exe
Shell\Open\command=regsvr.exe
Shell=Open

Answer 1

It is probably due to the fact that Windows new lines are \\r\\n instead of \\n . Also, you should escape the "\\" , so instead use "\\\\" .

Answer 2

Linebreaks under Windows \\r\\n are different from Linux's \\n .

So try replacing \\n with \\r\\n .
