running MD5 on a file throws error: OSError: [Errno 22] Invalid argument










0














I'm trying to run an MD5 on a list of files, but I'm getting an error and I'm not really sure why.



with open(local_file, 'rb') as f:
print(f) # prints: <_io.BufferedReader name='absolute/path/to/file.mkv'>
print(f.read()) # Throws the error: OSError: [Errno 22] Invalid argument
print(hashlib.md5(f.read()).hexdigest())


the line print(f.read()) Throws the following error




OSError: [Errno 22] Invalid argument

    If the file didn't exist, then the with open... line is what would throw the error and give a no such file error. No?

  • You are correct. I observed that the file is mkv. With python, reading a huge file into RAM causes issues. I remember seeing something similar in SO before. Let me find the link.
