Use binascii.unhexlify.

Or hexdigest_string.decode('hex')

Or hexdigest_string.decode('hex')

I would advise against this, as it's incompatible with Python 3.

I didn't know that, you actually made me look it up in the Python 3
FAQ. And yes, the difference is that decode will return bytes type
instead of a string. This may or may not be a problem (bytes type is
supposed to be immutable, so it can be used in many places where a
string is used now, ex. as a dict key).

No. The decode method on string objects is removed, you can only
*encode* strings, but not decode them.

This may or may not be a problem

The problem is this:

pyhashlib.sha1(b"Hallo").hexdigest().decode("hex")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'decode'
