Title
Body
I want to read a file byte by byte and check if the last bit of each byte is set: #!/usr/bin/python def main(): fh = open('/tmp/test.txt', 'rb') try: byte = fh.read(1) while byte != "": if (int(byte,16) & 0x01) is 0x01: print 1 else: print 0 byte = fh.read(1) finally: fh.close fh.close() if __name__ == "__main__": main() The error I get is: Traceback (most recent call last): File "./mini_01.py", line 21, in <module> main() File "./mini_01.py", line 10, in main if (int(byte,16) & 0x01) is 0x01: ValueError: invalid literal for int() with base 16: '\xaf' Anyone an idea? I didn't succeed using the struct and the binascii modules.
