Quoting

http://docs.python.org/dev/py3k/whatsnew/3.0.html#removed-syntax

"""
You can no longer write def foo(a, (b, c)): .... Use def foo(a, b_c): b, c = 
b_c instead.
"""

If there isn't a Python 3 version of PySVG you can try to run it through

http://docs.python.org/dev/py3k/library/2to3.html#to3-reference

to make the easy changes.
