#92208 — Function to show time to execute another function

Sometimes I just want to know how much time a function takes, but at
the same time I also want the result of the function. For this I wrote
the following function:
    def time_test(function, *args):
        startTime   = time.time()
        results     = function(*args)
        endTime     = time.time()
        print('It took {0} seconds'.format(endTime - startTime))
        return results

I can do:
    time_test(test_random, 100, 10 ** 5)
This outputs:
    It took 17.01685857772827 seconds
and returns:
    (98592, 100833, 0.977775133140936)

When executing:
    time_test(test_random, 100, 10 ** 6)
it outputs:
    It took 165.26371836662292 seconds
and returns:
    (997103, 1002009, 0.9951038363926871)

That only times the function. I explicitly mentioned I want both the
needed time AND the output.

Sadly the quality of the answers on this list is going down. Here I
get an alternative that does only half what I want and when writing an
alternative for ‘!find’ I am told I could use ‘!find’ (which only
works in ipython, not python and which also not works with Windows).

First of all, thank God it's a newsgroup, not a list.

Second, often the quality of an answer is deeply connected to the 
quality of a question. I've red your question, and I still have not 
clear what you want.

If you want a function that returns a result and a time elapsed, why 
don't you pack the time and the result in a tuple, a list or a 
dictionary? it takes 20 seconds, if you are slow.

Else if you want a function that prints time and result, why don't you 
print result more or less in the same manner you do with the time 
elapsed? it takes 20 seconds, if you are slow.

Else, can you explain exactly what do you want?

I've always thought of this as a list that is mirrored to a newsgroup,
not a newsgroup that is mirrored to a list. What is the true nature of
python-list (and others such as python-ideas)? What is it primarily,
what was it first, etc?

It's a mailing list mirrored to one official newsgroup, and at least one
unofficial newsgroup (gmane). It's also archived on various websites, plus
Google Groups.

As far as I know, python-list a.k.a. comp.lang.python is the only one of the
Python mailing lists with an official newsgroup mirror.

In *practice*, there's not much difference which comes first. Apart from
some spam, which gets filtered from the mailing list but not the newsgroup,
or vise versa, you can post to the mailing list or the newsgroup and the
message will show up on both.

comp.lang.python.announce also exists.

Sent via mailing list.

OK. So let me rephrase: Thank God the list is mirrired to a newsgroup...

My bad.

Well, it was not a question, it was sharing. I wanted something that
showed the needed time, but also the result. It was not a piece of
art, but something I thought could be useful to share.

I already did that. Sort of. I made a version that defaults to
printing the needed time and returning the result, but can me made to
put the time in a tuple with the result.

I must be very slow. :'-( It took more as 20 seconds.

It's both: they're mirrored to each other and I consider both to be 
first class citizens. In strict chronology I believe comp.lang.python 
existed first, but python-list has been around for long enough that the 
distinction now is really quite academic.

I would not be surprised to find that a fair majority of people told off 
on this list for abusing newsgroup etiquette in one way or another not 
only have no idea that this is (also) a newsgroup but don't even know 
what a newsgroup *is*.

They may also not know that it's a mailing list, nor what that is, 
because they're coming via Google Groups -- which uses the Usenet 
gateway -- or through gmane -- which comes in through the mailing list 
-- or some other web mirror.

I suggest that you stop asking so many question here.  Get your cheque 
book and go for paid support.

Cheques are still in use in Britain.  There was a move a year or so ago 
to get rid of them but too many people complained.  However I feel that 
they're doomed in the same way that cash is on the way out as reported 
here http://www.bbc.co.uk/news/business-32778196

Mark, that remark is uncalled for and completely out of line. Cecil is
perfectly entitled to ask questions here, and you are entitled to ignore
them. You're just pissed off because he rightly noted that your answer to
his question *doesn't solve his problem*.

First of all: it was not a question: I shared something I thought was
useful. You can disagree about it being useful, but there is in my
opinion no need for this kind of responses.

Giving a ‘solution’ that only does half of my solution is not very
useful. Also giving a solution I rejected/replaced is not useful. You
can disagree with the rejection/replacement, but giving it as an
alternative …

Giving disparaging remarks will not improve the quality of this
newsgroup. You will get rid of my ‘stupid’ questions and shares. But I
found that some of the things that I thought would be of very slight
interest resulted in very interesting discussions. If I and other
people do not post those ‘stupid’ things anymore, we will lose those
gems.

Mark: that was too abrupt, even if the OP was being serious (and I 
suspect he may not have been, despite the absence of a smiley).

Cecil: I don't know if you really meant that seriously, but it certainly 
comes across as ungracious if you did. If you meant it half-humorously, 
then you need to throw in a smiley or a wink to show that you were joking.

Yes, I was serious, but maybe I should have used some ‘honey’. When I
started posting questions here I was pleasantly surprised with the
very helpful responses, but lately I must say I see ‘answers’ that are
not only unhelpful, but potentially chasing people away. As I
explained in another post.

Maybe I am not very smart, but what is ungracious in pointing out that
in the reply on something I shared I think could be useful, the
‘solution’ does something else as what I shared?

And you also posted your solution. I fail to find any question in your
original posting at all.

> Sadly the quality of the answers on this list is going down. 

Maybe you should start asking questions that people are able to
comprehend so that you get an answer that you like.

Protip: Ditch the shitty attitude. I don't know if you're a jerk or not
but I know for sure that you sound like one. Makes it also much less
likely to get the answers you'd like.

Johannes

That is because there was no question: I just wanted to share
something I thought that could be useful. If you would have taken the
trouble to read a little, you would have known that.

I do not want answer I like, but an answer that is useful.
