Python checking file content with string

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

If you print content after reading it, what does it display? — g.d.d.c

You should parse your text into dictionaries and then compare... — JBernardo

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

So try replacing \n with \r\n.

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"\\".
