Python3中bytes和HexStr之間的轉換

1 Python3中bytes和HexStr之間的轉換

1. ByteToHex的轉換

   def ByteToHex( bins ):
       """
       Convert a byte string to it's hex string representation e.g. for output.
       """
   
       return ''.join( [ "%02X" % x for x in bins ] ).strip()
   
   

2. HexToByte的轉換

   def HexToByte( hexStr ):
       """
       Convert a string hex byte values into a byte string. The Hex Byte values may
       or may not be space separated.
       """
   
       return bytes.fromhex(hexStr)
   
   

3. 測試

   __hexStr1  = "FFFFFF5F8121070C0000FFFFFFFF5F8129010B"
   __hexStr2  = "FF FF FF 5F 81 21 07 0C 00 00 FF FF FF FF 5F 81 29 01 0B"
   __byteStr = "\xFF\xFF\xFF\x5F\x81\x21\x07\x0C\x00\x00\xFF\xFF\xFF\xFF\x5F\x81\x29\x01\x0B"
   
   
   if __name__ == "__main__":
       print( "\nHex To Byte and Byte To Hex Conversion")
   
       print( "Test 1 - ByteToHex - Passed: ", ByteToHex( __byteStr ) == __hexStr2)
       print( "Test 2 - HexToByte - Passed: ", HexToByte( __hexStr1 ) == __byteStr)
       print( "Test 3 - HexToByte - Passed: ", HexToByte( __hexStr2 ) == __byteStr)
   
       # turn a non-space separated hex string into a space separated hex string!
       print( "Test 4 - Combined  - Passed: ", \
             ByteToHex( HexToByte( __hexStr1 ) ) == __hexStr2)
