Ignorando el aumento de error al iterar a través de archivos con python

I'm currently working on a task where I need to iterate multiple executable file using pefile module the code is look like this

while True:
    try:
        for filename in glob.iglob('C:\Documents and Settings\Zha\Desktop\PE benign\*.exe'):
            pe =  pefile.PE(filename)

            print '%x' % pe.FILE_HEADER.NumberOfSections

    except:
        pass

My intention using try and except is to overcome error raise whenever an executable that raising an error where NT header gives Invalid signature because if I do not use try and except the code will stop at the point where it found an executable with invalid NT header signature

this is what the message looks like if I don't use try and except

PEFormatError: 'Invalid NT Headers signature.'

However using the code above will cause an infinite loop, is there any possible way to solve this?

Don't use an infinite loop then? Move your try más cerca to the exception; put it around the pefile.PE() call only. -

@TheGameDoctor Mind, that your string 'C:\Documents and Settings\Zha\Desktop\PE benign\*.exe' está mal, como ` is escape character. Correct it to 'C:\\Documents and Settings\\Zha\\Desktop\\PE benign\*.exe'` or to r'C:\Documents and Settings\Zha\Desktop\PE benign\*.exe' or use forward slashes 'C:/Documents and Settings/Zha/Desktop/PE benign/*.exe' -

No use el while True loop. Simply move the try except en el for bucle:

for filename in glob.iglob('...'):
    try:
        pe = pefile.PE(filename)
    except PEFormatError as err:
        print "{} in file '{}'".format(err, filename)
        continue

    print '{}'.format(pe.FILE_HEADER.NumberOfSections)

Also, your string formatting syntax isn't wrong, however, format is the preferred way to format strings.

thanks this is helpful, just a little correction on part where except pefile.PEFormatError as err. But in general this is great thanks - TheGameDoctor
