I'm wondering if int('0x20') (without the
explicit radix value 16) should work. Doesn't the '0x' prefix mean
that it's a hex number, radix 16, unambiguously?<br><br>
OTOH, I would not expect int('033') to interpret
the value as if the radix is 8, because the "leading 0 means
octal" convention is both very old and a really really really bad
idea! But 0x prefix doesn't mean anything else -- does it?<br><br>
I'm waiting for the Pascal programmers to say that
int('$20') should work, returning 32, because $ is the
Pascal-language equivalent of '0x' -- but it shouldn't. To someone
entering data into a computer program, '$20' is not a value in hex, it's
an amount of money!<br><br>

<blockquote type=cite class=cite cite="">I just checked it myself to see
what works and what doesn't. You're right that it doesn't work when
putting '0x' in front of it. However, when I just do int('20', 16) it
returns 32, which is correct.<br>

It is a bit weird though, that int(hex(20), 16) returns an error and I
think that should be fixed. [snip]<br>

<dd>Same for long. Python library reference isn't clear on this point,
but <br>
<dd>my reading doesn't support this misfeature since one can use radix
