You can embed the markdown inside the loop using cat(). Note: you will need to set results=”asis” for the text to be rendered as markdown. Note well: you will need two spaces in front of the \n new line character to get knitr to properly render the markdown in the presence of a plot out. … Read more
TL;DR Your best bets are usually a for-of loop (ES2015+ only; spec | MDN) – simple and async-friendly for (const element of theArray) { // …use `element`… } forEach (ES5+ only; spec | MDN) (or its relatives some and such) – not async-friendly (but see details) theArray.forEach(element => { // …use `element`… }); a simple … Read more
Using a foreach loop without a key: foreach($array as $item) { echo $item[‘filename’]; echo $item[‘filepath’]; // To know what’s in $item echo ‘<pre>’; var_dump($item); } Using a foreach loop with a key: foreach($array as $i => $item) { echo $array[$i][‘filename’]; echo $array[$i][‘filepath’]; // $array[$i] is same as $item } Using a for loop: for ($i … Read more
Yes, they do completely different things. pass simply does nothing, while continue goes on with the next loop iteration. In your example, the difference would become apparent if you added another statement after the if: After executing pass, this further statement would be executed. After continue, it wouldn’t. >>> a = [0, 1, 2] >>> … Read more
The problem is that “scanf()” can leave unread data in your input buffer. Hence the “infinite loop”. Another issue is that you should validate the return value from scanf(). If you expect one integer value … and scanf returns “0” items read … then you know something went wrong. Here is an example: #include <stdio.h> … Read more
To augment Dave’s answer, here is a translation schema for ‘for-comprehensions’ from Scala language specification: A comprehension for (enums) yield e evaluates expression e for each binding generated by the enumerators enums. An enumerator sequence always starts with a generator; this can be followed by further generators, value definitions, or guards. A generator p <- … Read more
One thing you could do (this of course depends on what you are trying to accomplish) is: Store the necessary information (i.e. like a loop counter) in a spreadsheet or another permanent store(i.e. ScriptProperties). Have your script terminate every five minutes or so. Set up a time driven trigger to run the script every five … Read more
Re-posting a modified version of my answer from optimized sum of an array of doubles in C, since that question got voted down to -5. The OP of the other question phrased it more as “what else is possible”, so I took him at his word and info-dumped about vectorizing and tuning for current CPU … Read more
Create an anonymous function which accepts i as a parameter and returns that certain function: for (var i = 0; i < 3; i++) { a.push((function(i) { return function() { alert(i); } })(i)); } for (var j = 0; j < 3; j++) { a[j](); } Or do something similar: create an anonymous function which … Read more
As an alternative to @Mark Byers’ approach, you can use while True: guess = 50 # this should be outside the loop, I think while True: # infinite loop n = raw_input(“\n\nTrue, False or Correct?: “) if n == “Correct”: break # stops the loop elif n == “True”: # etc.
