问题 I need to extract strings from nested brackets like so: [ this is [ hello [ who ] [what ] from the other side ] slim shady ] Result (Order doesn't matter) : This is slim shady Hello from the other side Who What Note, the string could have N brackets, and they will always be valid, but may or may not be nested. Also, the string doesn't have to start with a bracket. The solutions I have found online to a similar problem suggest a regex, but I'm not sure it will work in this case. I was thinking

问题 I am using argparse in python3, and I get some strange things: A short version of code that I'm using is: argparser = argparse.ArgumentParser(description='add/remove items') argparser.add_argument('-a', action='append', metavar="Item(s)", help='add one or more items to the list') argparser.add_argument('-r', action='append', metavar="Item(s)", help='remove one or more items from the list') args = argparser.parse_args() When I run the script with the -h flag, I get this output: usage: test.py

问题 I want to create a hotkey Ctrl + ( that adds brackets to a phrase. I.e select x-1 to get (x-1) . How to program this function? I write a lot of phrases such as: x+1/(x-1)^2 so it would be helpful to have a hotkey to add brackets. 回答1: ^(:: SendInput, ^c Sleep 10 Clipboard = (%Clipboard%) SendInput, ^v return This implies that you are actually pressing CTRL+SHIFT+9 (since you don't have a ( key). I did a quick test and it will add round brackets to anything you highlight. I would recommend

问题 This question already has an answer here : Regex word boundary alternatives inside parentheses does not work? (1 answer) Closed 5 years ago . I have noticed that the word boundary \bword\b does not work inside brackets when doing a preg_replace() in PHP. Specifically, I'm trying to exclude the full word > (which stands for > in HTML), but since the word boundary does not trigger inside brackets as in [^\b>\b] , any of those characters by itself, like g or & , will be detected as a non-match.

问题 I love/hate the regex because of usefulness/hardness. (I don't why but I can't construct pattern :( ) I have some records in my database field like this [(ip1=192.x.?.100)(id1=125485smds65)(date1=11.02.2011-15:00/15.06.2012-17:30)(text1=Some text that can include all brackets and/or parentheses & any chars etc, like < ( text . } , [ any ) ] { etc.**)][(ip2=x.x.20.?)(num2=1235845)(text2=many other words :))]... Ok, I want to return an array that contain value as; $result[ip1] = 192.x.?.100;

问题 following code is given: if (c2-c1==0) if ( c1 != c3 ) {...} How do I interpret this code? The first if-statement comes without {} . Is the code above equal to the following code?: if (c2-c1==0){ if ( c1 != c3 ) {...} } 回答1: Yes. The if statement applies to the next statement after it - which happens to be another if in this case. 回答2: Yes, they are equivalent 回答3: Absolutely. Putting no brackets means that the only instruction in the first if is the other if, which can contains anything you

问题 I don't understand why I don't need brackets in this case for (int i = 0; i < 10; i++) if (num[i] < min) min = num[i]; And why I need brackets in this case int num[10], min; for (int i = 0; i < 10; i++) { cout << "enter 10 numbers" << endl; cin >> num[i]; } 回答1: Both the for and the if have to be followed by a "statement". A "statement" can be a simple statement, like min = num[i]; , a more complicated one like if (num[i] < min) min = num[i]; or it can be a compound statement (i.e., zero or

问题 I have an Angular 5 application with a series of components. Some of the components are children of others, and some are not.

问题 This question already has an answer here : Where can I get info on the object parameter syntax for JavaScript functions? (1 answer) Closed 3 years ago . I was reading some tweets and I came across this tweet by Dan Abromov The syntax has me confused. const Font = ({ children }) => <Block... What is the point of { } around children? Clearly its not an object. I presume its ES2015 feature. Many thanks 回答1: It's a destructuring binding pattern. It indicates that the parameter children should be
