Nadeem Vawda <nadeem.va...@gmail.com> added the comment:
The behaviour of int() can be made consistent with the syntax for Python
integer literals by specifying a base of 0:
>>> int("0050", 0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 0: '0050'
>>> int("0o050", 0)
40
>>> int("0x050", 0)
80
>>> int("0b010", 0)
2
As for changing the default behaviour, I think it would be a bad idea.
Having ``0050'' be an invalid token is perhaps jarring to people used to
C/C++/Java/etc., but at least attempts to use it fail loudly and
obviously. Having it be valid and yet mean something different could lead
to nasty surprises for the unsuspecting.
