Any of these works if your goal was literally to print 1 through 5 (and there's no need to create a list of lambdas in that case) but outside of the toy example, there may be situations where you do need to capture the lambdas for future use. My code was intended to preserve the exact setup and and simply correct the mistake, which is that the closure wasn't capturing the loop variable at that point in time.

Edit: I also assume the toy example was not where the guy ran into issues - it was probably the simplest thing he could do to illustrate the surprising semantics, which he ran into in more complex code. Rewriting it to avoid the semantics entirely may be much more inconvenient in other cases.

Thats actually a good point, Im sure his actual code wasnt a list of 1-5

So I made a vow to look at itertools whenever somerthing like this comes up. I think this would work well

x = itertools.imap(f, [1,2,3,4,5])

x is now an interator which, each time it's looped through, will call f on the next value of the 2nd argument (which here is [1,2,3,4,5] but can also be another iterator)

You can then execute like
for a in x: pass
(you don't have to do anything in the loop, because it runs f(whatever) for each whatever in the input)

You could also just have
list(x)
(and ignore the return result)

candybar: yeah, I know, you want to in some way make a single variable that encapsulates the functions and the data, so that something else somewhere else can call it. I'd argue that the itertools example above does an OK job of this, and is probably quite a bit clearer to observers

(in case it's not clear, imap() does the same thing as map() except instead of applying the function to all the list elements "now", it does it when the iterator is invoked)

In JS at least, it's not even about encapsulating the data necessarily - you run into this most often when you're doing something asynchronous, which in JS almost always involves closures. Something like:

I assume this kind of code is not idiomatic in Python so you're less likely to run into this issue.

There's a career/bootcamp thread on this page that you should look at, and a bigger bootcamp or career change thread or something that has gone 1-3 weeks without a post.

Start the application process for App Academy and Hack Reactor right now, they'll tell you what to start learning. If you get accepted, I'm not sure whether or not you should take them. See threads.

No matter what you do, be prepared to apply to 1,000 jobs or more. If you aren't prepared to apply to 10+ jobs per weekday without a break until you get a job, then don't bother with bootcamps or any of it except possibly a Master's or second Bachelor's.

Either way, take the continuation course on edx...I'm about to take it myself.

The inner list evaluates correctly, but the outer list evaluates to something. The reason this version works is because your version actually did work, but since your function only returns one value, it returned the last value of the list of each call. Since it already evaluated f(i), the final result here is a bunch of None, which would have been 5 each time in your original code.

This would be better as a list comprehension, with a caveat:

or if he is delaying evaluation, he can use a generator object:

but a generator is a use-once item because it delays evaluation:

but there is no no need to wrap the expression in brackets:

Since lambda is an anonymous function, you can pass it arguments:

If you use a function that does return something, there is no list of None:

A function can only return a scalar, a list, tuple, dictionary, set, etc. The problem is that, as written, you are evaluating the function and returning a scalar. Even if I replace f() with sqare(), the same issue happens because I am returning a scalar, which is going to be the last result. This is expected behavior:

"Not losing information" depends on who you ask for numerical widening. Java is happy to implicitly treat a long as a float. (Even int to float can be lossy if you care about the exact value of the integer.)

A few weeks ago blackize mentioned they used hound and code climate.

Anyone else have tools they use to measure code quality/enforce style guides/etc?

We're doing angular/node and using github if that matters.

We use hound. It integrates with our GitHub based CI system and shows comments in pull requests for violations. We dont block deploys if there are violations but hound is pretty good for ruby code.

cool, thanks.
About 10 seconds after posted I realized I should look at the github integrations and there's a bunch there that I've been going through.

Thanks for the response, Baltimore. Are you referring to a specific continuation course? I've been so fixated on the one I'm taking now I haven't examined what other courses are available yet.

Also, question, are most/all internships open to undergrad/masters students only?

I meant the next MIT CS course on edx that is more advanced Python.

No, internships are definitely not student-only.

i know CTH has had some security threads over the years, I wonder if this forum would do well with a security programming thread

learned how to make a multi-threaded archive password cracker today, woo!

<3 thanks.
Got super lucky with that hurricane. Jogged just north and we barely got a breeze over this way.

thanks dave. didn't see your message before.

was nothing more than a mild rain where i lived. so much prep in vain!

Just got back from Jax London.

Apparently if you aren't doing microservices and event sourcing you are the lamest of the lame.

Extra points for using serverless lambdas.

Seems legit.

After Wilma I always keep an eye on storms and do prep ASAP. I was ready to book a few nights across the state with how scary this one was looking.
The amount of people I know who did zero prep and said "it's not going to hit us, they never do" drives me nuts. But they were right, again.

Anyone ever done a first phone screen with a recruiter and they end the call saying that they will send an email to schedule the technical phone screen, but then they never email you?

Phone screen was low energy, I'm not sure how I am suppose to fake enthusiasm for a company that makes network switches and routers. This was through a referral so I feel like she just called just as an obligation. Just not on my ball game today.

Hopefully I am just reading into things wrong like I always do, and I'll get an email on Monday to set up a technical phone screen. But someone on glassdoor had the same exact experience so I'm not keeping my hopes up.

Warming up to itertools are we?

Yes all kinds of **** happens in seeking new employment. The one thing that you need to do in handling it is to not take this **** personally, if you do it will drive you insane. Of course people often tell you lies, mislead you, and treat you like a piece of crap. It isn't necessary but goes with the territory. I find the machinations to be mostly silly and I have gotten to the point where it is often amusing. There are all kinds of BS you will encounter. Just realize that you're involved in a process that has a lot of flaws. Say your chances of landing a position averages like 5% per inquiry, if you inquire about 100 positions you will almost certainly get an offer. It takes time and requires some mental toughness. Since you will probably find a lot of dead ends, I would be mindful of looking at how much time it will take you to get to the interview stage for a particular position.

Don't feel bad. It is just prioritizing on their end. Also, why are you applying for a job that you think is so boring that you need to muster up an extra reserve of sociopathic enthusiasm to make it to a second phone interview?

Maybe jobs are harder to come by in this new economy than I thought. But if you can't fake it for 15m on the phone, it sounds like it'll be a nightmare.

NB: Maybe you can figure out why my router just gives up on life if I buy a cheapie personal one. I think its NAT table just kinda ragequits and it starts resetting every hour. (tbf this problem is like 4 years old. I just buy $200 router now and we're all good)

Looking at it again and reviewing the glassdoor reviews, perhaps I wasn't the right cultural fit. I didn't show enough enthusiasm in terms of activities outside of work. I got the vibe that their employees like to hang out outside of work. Which for me is always kind of weird. I like to keep my work and personal life separated.

man after about a day of it I strongly regret all the time I could have been using linux mint and used other crap instead.
