Are "bytes" values objects in Python?

Yes, "bytes" values are objects in Python.
In fact, all data values in Python are objects.
In Python, "bytes" is defined as an object class with the following interesting properties, constructors, and methods:
bytes.__doc__ - Property holding a short description of "bytes" objects.
bytes.__new__() - Constructor returning a "bytes" object. It can be invoked as bytes(). For example:
>>> bytes.__new__(bytes,b'FYIcenter.com') b'FYIcenter.com' >>> bytes(b'FYIcenter.com') b'FYIcenter.com'
bytes.__getitem__() - Instance method for the [] operation, returning the byte (as an "int") of the bytes at the given position. For example:
>>> b'FYIcenter.com'.__getitem__(2) 73 >>> b'FYIcenter.com'[2] 73 >>> hex(73) '0x49' >>> "\x49" 'I'
bytes.find() - Instance method searching for the given byte and returning the position in the bytes. For example:
>>> b'FYIcenter.com'.find(b'I') 2 >>> b'FYIcenter.com'.find(73) 2
You can use the dir(bytes) function to see all members of the "bytes" class:
>>> dir(bytes) ['__add__', '__class__', '__contains__', '__delattr__', '__dir__', '__doc__', '_ _eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs __', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__' , '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__' , '__str__', '__subclasshook__', 'capitalize', 'center', 'count', 'decode', 'end swith', 'expandtabs', 'find', 'fromhex', 'hex', 'index', 'isalnum', 'isalpha', ' isdigit', 'islower', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpar tition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swap case', 'title', 'translate', 'upper', 'zfill']
