I want to convert an 32-byte (although I might need other lengths) integer to a bytes object in python. Is there a clean and simple way to do this?

An int value can be converted into bytes by using the method int. to_bytes(). The method is invoked on an int value, is not supported by Python 2 (requires minimum Python3) for execution.
b means bytes , not binary. \x00 is not string 0 but char with code 0 which can't be displayed so Python shows its code. – furas.
We can use the built-in Bytes class in Python to convert a string to bytes: simply pass the string as the first input of the constructor of the Bytes class and then pass the encoding as the second argument.
Python bytes() Function The bytes() function returns a bytes object. It can convert objects into bytes objects, or create empty bytes object of the specified size.
to_bytes(length, byteorder[, signed]) is all you need starting from 3.2. In this case, someidentifier.to_bytes(4,'big') should give you the bytes string you need.
