try:

except Exception as e:
cgitb.text(sys.exc_info())

we get the output

This might be a cython issue then, but I will dig into an example case. Please
be patient.

New submission from steven Michalske :
We are using some compiled cython modules with c++ 11 features.
This prohibits us from instructing users to install python from the python.org
download.
Please consider using clang with support for C++ 11 and higher.
This would move the minimum OS X

Argh, I swear I proofread this...
print([a[x] for x in [slice(y+3, y-1, -1) for y in range(0, len(a), 4)]])
[[], [7, 7, 6, 5]]
Catching my explicit case, I changed my code to:
print([a[x] for x in [slice(y+3, y-1 if y > 1 else None, -1) for y in rang
New submission from steven Michalske:
The slicing and using inputed math is is necessary to provide a special case to
make the code behave as expected.
Unless I'm missing something. Like we can't do this, as we loose negative
indexing from the end of the file?

The asyncio documentation should comment on how to mute and increase some of
it's logging.

The asyncio module logs information with the logging module in the logger

The RE compiler will not error out, with a back reference in there...
It treats the {\1} as a literal {\1} in the string.

New submission from steven Michalske:
When using the @property decorator the wrapped functions are not exposed for
source introspection. (At least I can't see how they are.)
The issue is then that Ipython "%psource" will show the source for the
@property as opposed to the f

Sorry my request is for output, I am not requesting input. The examples were
for showing the use in other contexts of using an underscore as a word (4 hex
digits) seperaror.
My assertions are from another area aside from computer languages, but from

I'll work on a proposal for the ideas list.
Other language examples to keep this in a thread though.
perl -e 'print 0x1234_abcd; print "\n";'
C/C++ seems to not support the underscore.
Lua unsupported.

New submission from steven Michalske :
It is a common practice to separate hex digits with a "thousands" separator
every 4 hex digits.
0x1234_abcd
Although python does not accept the _ as a thousands separator in hex notation,
neither is the thousands separator in base 10

New submission from steven Michalske :
I started using the .format() on strings and was surprised that it was lacking
an built in format specifier for engineering notation.
For those unfamiliar with engineering notation it puts the exponent of the
number in modulo 3 so that it is in alignment

Agreed, add is the correct word, I used update because i created a set from
the list that optarg created with append.

As a complement to the append action, an update action would update a set with
new values.
