Or maybe bundle pychecker with idle?
$ cat tmp.py
def test(x, a=[]):
a.append(x)
return a
for i in range(5):
print test(i)
$ pychecker tmp.py
Processing tmp...
[0]
[0, 1]
[0, 1, 2]
[0, 1, 2, 3]
[0, 1, 2, 3, 4]
Warnings...
tmp.py:2: Modifying parameter (a) with a default value may have unexpected
consequences
Though it might be interesting to ask a newbie what he expects when warned
of "unexpected consequences" ;)
