Every Python programmer gets this message occasionally:
IndexError: list index out of range
The message tells you where the error occurred, but it doesn't tell you
what the range and the offending index are. Why does it force you to
determine that information for yourself when it could save you a step
and just tell you? This seems like a "no-brainer" to me. Am I missing
something?

I think you have a point. I am curious to see how far people are willing
to go to defend this omission. It promises to be entertaining.

Add "Syntax Error: invalid syntax" to the list ...

I'm not sure that anybody is going to defend it as a deliberate omission.
Rather, they (like I) will encourage to OP to submit a patch that fixes the problem.

Now, that would be rather silly. I would have to familiarize myself
with the code for the Python interpreter, then send a patch to the
maintainers (and hope they notice it in their inboxes), while the
maintainers themselves could probably "fix" the problem in two minutes
flat. No thanks!
My suggestion is trivial to implement and would benefit every Python
programmer (even if only slightly), so I don't think it is too much to
ask for.

Add "Syntax Error: invalid syntax" to the list ...
But at least if you're using IDLE, the point of syntax error
is highlighted.
When I was a programmer, I thought as a programmer,
I spake as a programmer and I understood as a programmer.
But when I became a User, I put away such childish things. me********@aol. com wrote:

Same when using the interactive interpreter, the point of syntax error
is highlighted with a caret. However the highlighting of WHERE is
useless to people who don't have a clue WHAT the error is, and it needs
a forensic guru to suss it out as for example Peter Otten did, only
yesterday:
"""
Are you perhaps mixing tabs and spaces?
>>def f():

And I believe that answers your original question.
PS: begging for a fix on comp.lang.pytho n is even less likely to get the
developer's attention than posting a patch. They listen to patch submissions
much more than comp.lang.pytho n. At the very least, you should submit a bug
report even if you don't want to take the opportunity to learn how to fix it
yourself.

Well, more information would be better, but at least it's
not as bad as Windows:
Application xxx could not be started because a
required file could not be found. I know the name
of the file but I am not going to tell you what
it is.

What that has to do with this thread escapes me, but since you
apparently have nothing better to do than track down information that
should have been provided to you, it's no wonder you don't have enough
time to do your own laundry.
When you call information to get a phone number, do you first ask if
they have the number, then call back a second time to get it if the
answer is yes?
If a policemen gives you a speeding ticket, do you expect him to tell
you how fast he thinks you were going, or are you content to wait for
the court date?

Often times, I do not want to specify the width of a div. Rather, I
just want it to expand to be just wide enough to enclose its contents.
Since this is how tables behave, I tried setting "div {display:
table;}" and it worked - but only in firefox, but not in IE6. Are there
any alternatives? Am I alone in needing this type of functionality?
Thank You.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
