How to Read-in Binary of a File in Python

In Python, when I try to read in an executable file with 'rb', instead of getting the binary values I expected (0010001 etc.), I'm getting a series of letters and symbols that I do not know what to do with.

Ex: ???}????l?S??????V?d?\?hG???8?O=(A).e??????B??$????????:    ???Z?C'???|lP@.\P?!??9KRI??{F?AB???5!qtWI??8
