Nah.
>>> eval("[0] * (2 ** 31)")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<string>", line 0, in ?
OverflowError: integer exponentiation
>>> eval("[0] * (2 ** 30)")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<string>", line 0, in ?
MemoryError
eval("[0] * (2 ** 25)") seems to be about right for my machine (not
that I let it finish).
Cheers,
