New submission from Lucas Bertoldo <lvcas.berto...@gmail.com>:
Basically, I typed:
>>> m = (list(), list())
then I got, this, as expected:
>>> m[0] += [1]
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
m[0] += [1]
TypeError: 'tuple' object does not support item assignment
but, when I checked the variable...
>>> m
([1], [])
---------------------------------
Saying the least, one can kind of assing a value to a tuple of lists and get
the expected result, but with the trackback still showing up.
