PEP 3114 describes this change. An excerpt about the motivation: This PEP proposes that the next method be renamed to __next__, consistent with all the other protocols in Python in which a method is implicitly called as part of a language-level protocol, and that a built-in function named next be introduced to invoke __next__ method, … Read more
Next Weekday This finds the next weekday from a specific date (not including Saturday or Sunday): echo date(‘Y-m-d’, strtotime(‘2011-04-05 +1 Weekday’)); You could also do it with a date variable of course: $myDate=”2011-04-05″; echo date(‘Y-m-d’, strtotime($myDate . ‘ +1 Weekday’)); UPDATE: Or, if you have access to PHP’s DateTime class (very likely): $date = new … Read more
You can use a GoTo: Do ‘… do stuff your loop will be doing ‘ skip to the end of the loop if necessary: If <condition-to-go-to-next-iteration> Then GoTo ContinueLoop ‘… do other stuff if the condition is not met ContinueLoop: Loop
To read only the first row of the csv file use next() on the reader object. with open(‘some.csv’, newline=””) as f: reader = csv.reader(f) row1 = next(reader) # gets the first line # now do something here # if first row is the header, then you can do one more next() to get the next … Read more
In this case you need to go up to the <tr> then use .next(), like this: $(obj).closest(‘tr’).next().find(‘.class’); Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this: $(obj).closest(‘tr’).nextAll(‘:has(.class):first’).find(‘.class’);
I don’t know if this was the original error but you can get the same error if you try to call f.tell() inside of a line-by-line iteration of a file like so: with open(path, “r+”) as f: for line in f: f.tell() #OSError which can be easily substituted by the following: with open(path, mode) as … Read more
This appears to be a variable naming convention in Node.js control-flow code, where a reference to the next function to execute is given to a callback for it to kick-off when it’s done. See, for example, the code samples here: http://blog.mixu.net/2011/02/02/essential-node-js-patterns-and-snippets/ Let’s look at the example you posted: function loadUser(req, res, next) { if (req.session.user_id) … Read more
for uses iter(song) to loop; you can do this in your own code and then advance the iterator inside the loop; calling iter() on the iterable again will only return the same iterable object so you can advance the iterable inside the loop with for following right along in the next iteration. Advance the iterator … Read more
This is what the res.locals object is for. Setting variables directly on the request object is not supported or documented. res.locals is guaranteed to hold state over the life of a request. res.locals (Note: the documentation quoted here is now outdated, check the link for the most recent version.) An object that contains response local … Read more
This might be a wrong answer to your question. I’ll remove it in that case, but maybe you can use it for what you want to achieve: int[][] it = {{1,2}, {3,4,5}}; OfInt iterator = Arrays.stream(it).flatMapToInt(x -> IntStream.of(x)).iterator(); iterator.forEachRemaining((IntConsumer) System.out::print); Stream the jagged array, flatmap it into one single IntStream and then do what you … Read more
