When I try to start it form the Python command line, it says it is a

Thanks. Is it possible to just disable the vanilla version? I may want
to switch between the two. Most users of the program I'm about to
modify use the vanilla version. At some point, I may want to go back to
it to verify that in their world all is OK.

Hello everyone,
What is the pythonic was of selecting the first element of a
list matching some condition?
I often end up using
[x for x in lst if cond(x)][0]
This looks bad and raises IndexError if nothing is found which
is ugly too.
Thanks.

1) itertools.dropwhile(cond, lst) will return a list with the desired element
first.
i think in order to use this, the OP needs to invert his Boolean logic
because it *drops* elements while the conditional is True. as soon as
it hits False the 1st time, all remaining elements (including the

You know, that's a great idea :-) Just using options I could keep my initial
checks the same (e.g. making sure needed options were included by looking at
options.foo) and pass it along without adding much to the query function.

I have a problem with understanding how lists, strings, tuples, number
types and input arguments all interact with each other.
I have this program, in which I can use the *a structure to input
unlimited arguments.
As an example, if I use three arguments, it looks like this:
