In Python, is there an option to create a custom string class, that could be created by typing something like:
a = b"some string"
a.someCustomMethod()
Just like python has its u"" and r"" strings?

It's straightforward to write your own string class, but you can't get the construction syntax you want. The closest you can get is
a = MyString("some string")
where MyString is your custom class. I suppose you can alias b = MyString if you want.
Also, note that b"some string" is already the bytestring literal syntax. In Python 2, it just makes a regular string. In Python 3, it makes a bytes object, since regular strings are unicode in Python 3.

Note that you can subclass
str or UserString to create MyString and gain all the properties you'd expect from a normal string in addition to your new property. See docs.python.org/2.7/library/userdict.html?#module-UserString and stackoverflow.com/a/4699190/1970751
typing.NewType, but actually it seems to be about basic OOP in python.
