Re: Best way to check if there is internet?

A front end eng sent me this for how to check for the internet in JS https://html.spec.whatwg.org/multipage/system-state.html#dom-navigator-online But it also says: "This attribute is inherently unreliable. A computer can be connected to a network without having Internet access." As discussed h

Thanks for the function but i think having the function as described won't return True all time Me: dipping my foot in hot water, yes we can go ... In the sprit of "practicality beats purity", devs needs a function XD Kind Regards, Abdur-Rahmaan Janhangeer about

One-liner to merge lists?

Hi all I think this should be a simple one-liner, but I cannot figure it out. I have a dictionary with a number of keys, where each value is a single list - >>> d = {1: ['aaa', 'bbb', 'ccc'], 2: ['fff', 'ggg']} I want to combine all values into a single list - >>> ans = ['aaa', 'bbb', 'ccc'

Re: One-liner to merge lists?

Frank, Given this kind of data: d = {1: ['aaa', 'bbb', 'ccc'], 2: ['fff', 'ggg']} You seem focused on a one-liner, however ridiculous or inefficient. Does this count as a somewhat weird one liner? comb = []; _ = [comb.append(v) for v in d.values()] If you run the code and ignore the returned

Well, nice perspective. It's a valid consideration, sound theory but poor practicality according to me. It you view it like this then between the moment we press run or enter key on the terminal, our Python interpreter might get deleted. We never know, it can happen. Though it's nice to go in a

Re: Best way to check if there is internet?

As usual, his discussion is wandering a bit. Yes, some things are not reliable but sometimes a heuristic answer is better than none. Internet connections are beyond flaky and worse the connection you want may be blocked for many reasons even if other connections you try are working. Any number

I've got my answers but the 'wandering' a bit on this thread is at least connected to the topic ^^. Last question: If we check for wifi or ethernet cable connection? Wifi sometimes tell of connected but no internet connection. So it detected that there is or there is no internet ... -- https://m

Re: One-liner to merge lists?

I had to think about it too, David. Renaming it lets it make a bit more sense: [item for sublist in d.values() for item in sublist] This spells it out for me that you are taking one list within the main list at a time and then taking one item at a time from the list. Since the nesting is consi
