Summary: unexpected floating point exponent behaviour
Initial Comment:
There's a problem with exponents and numeric literals:
017e4 should be about 150k, but python gives 170k.
Same with hexints, 0x12e4 should be 180k, but python
gives 4836.
I think that python should either throw an error or do
it right.

Closing as invalid. Octal and hex notations apply only to
integer literals (see the reference manual). 0x12e4 is an
integer hex literal ('e' is a hex digit! so are a, b, c, d, and f),
and 4836 is its correct decimal equivalent. 017e4 is a
decimal float literal, denoting the same value as 17e4 (i.e.,
the presence or absence of leading zeroes has no effect on
the meaning of decimal float literals -- and all float literals in
Python are decimal float literals).
