Why do you want to hash the address ? The address is a hash itself.
But alright.. whatever.. First, you need to define what hash function you want to use. I can only see "hash 160".
There is no "hash 160".
I guess you are referring to the RIPEMD-160.. ?
You can use
hashlib:
>>> h = hashlib.new('ripemd160')
>>> h.update(b"YourString or address or whatever")
>>> h.hexdigest()
Output will be the RIPEMD-160 hash of the input.
But the chances are high you are trying to accomplish something which doesn't help you at all.
Instead of asking how to do that particular step, start from the beginning and explain what you are trying to accomplish (and please explain detailed why you need to hash the hash of a public key, it doesn't make sense for me).
