# constants
EOH = b'\r'[0] CHAR = b'C'[0] DATE = b'D'[0] FLOAT = b'F'[0] INT = b'I'[0] LOGICAL = b'L'[0] MEMO = b'M'[0] NUMBER = b'N'[0]
This is not beautiful code.
In this case, I think the intent would be better captured with def ASCII(c): return c.encode('ascii') EOH = ASCII('\r') # 0D CHAR = ASCII('C') # 43 DATE = ASCII('D') # 44 FLOAT = ASCII('F') # 46 INT = ASCII('I') # 49 LOGICAL = ASCII('L') # 4C MEMO = ASCII('M') # 4D NUMBER = ASCII('N') # 4E This expresses the intent that a) these are really byte values, not characters, and b) the specific choice of byte values was motivated by ASCII.
