testall.py (StorytellingAlice)

I do not know yet, how python is involved in Alice, (saw jython2.1) and got down to the test directory (.../lib/test) and tried "python testall.py"
and got
File "/cygdrive/c/Users/Peter/Downloads/StorytellingAlice/Required/jython-2.1/Lib/test/test_grammar.py", line 32, in <module>
assert -2147483647-1 == 020000000000, 'max negative int'
AssertionError: max negative int

If Alice depends on it ... something has to be adjusted, either the (python)test or something inside alice?

I am very much interested in Java and Python .... (I built lots of mathematical Java-applets, Python up to now only .... mini examples)
