Your code, properly indented, should look like this: def update_bullets(bullets): “””Update position of bullets and gets rid of old bullets””” #Update bullet position bullets.update() # Get rid of bullets that had dissapeared for bullet in bullets.copy(): if bullet.rect.bottom <= 1: bullets.remove(bullet) print(len(bullets)) Python code requires proper indentation at all times. Whitespace matters (unlike C)! I … Read more
I suggest placing all your valid characters into a string, then using the % operator. const std::string valid_characters = “abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*”; const unsigned int shift_offset = 13; std::string::size_type position = valid_characters.find(incoming_character); position = (position + shift_offset) % valid_characters.length(); char result = valid_characters[position]; You will have to check the position value because find will return std::string::npos if … Read more
To use Excel formula in VBA you have two choices: you can either Evaluate the function string as in @YowE3K’s example given here, or alternatively you can use the WorksheetFunction method to perform most Excel functions. The Evaluate method is best if you want to do a fixed formula like your example suggests and return … Read more
Try this change: RANDOM_COR=random.randrange(5,6) COUNT = 0 def check_xy_data(): global COUNT With COUNT inside check_xy_data, you set it back to 0 on every call. It can never reach more than 1. Your check is whether it’s in the range 5-6. This is never true, so you can never leave the loop. Note that trivial debugging … Read more
That’s why there are debug tools like gdb (just google for it 😉 ). This is the backtrace: #0 0x00000000004009ba in node::setnext (this=0x0, x=0x614cc0) at a.cpp:25 #1 0x0000000000400c18 in list::insertend (this=0x7fffffffdf10, x=45) at a.cpp:109 #2 0x00000000004008df in main () at a.cpp:137 that means in line 137 there is a function call (l.insertend(45)), then in line … Read more

As far as function pointers in C go, you need to pass the state as an extra parameter. That’s in opposition to languages like python, javascript or C++ that have closures. And that means storage duration needs to be considered for that extra structure. C programmers do make use of function pointers. And you can’t … Read more
What you need to do is use JSONSerialization to get your JSON object from data. Also in Swift 3 use URLRequest and URL instead of NSMutableURLRequest and NSURL. func requestPost () { var request = URLRequest(url: URL(string: “https://oakkohost.000webhostapp.com/test.php”)!) request.httpMethod = “POST” let postString = “numQue” request.httpBody = postString.data(using: .utf8) let task = URLSession.shared.dataTask(with: request) { … Read more
DDPT is an array of integers, as evidenced in this line: DDPT = [int(round(pt*TCV)) for pt in [.3,.5,.2]] DDPT[PT] is some integer, and you are trying to iterate through that. Hence the error. I would recommend giving your variables more descriptive names so these issues are easier to debug. edit: for num_iters in DDPT: for … Read more
Try this and see if it works. $args = array( ‘post_type’ => ‘post’, ‘tax_query’ => array( ‘relation’ => ‘AND’, array( ‘taxonomy’ => ‘category’, ‘field’ => ‘slug’, ‘terms’ => array( ‘vocalist’ ), ), array( ‘relation’ => ‘OR’, array( ‘taxonomy’ => ‘category’, ‘field’ => ‘slug’, ‘terms’ => array( ‘pop’ ), ), array( ‘taxonomy’ => ‘category’, ‘field’ => … Read more

How can I code a two-dimensional array of 50 rows and 50 columns into a function which randomly assigns an asterisk to an element? solved How can I code a two-dimensional array of 50 rows and 50 columns into a function which randomly assigns an asterisk to an element?
Don’t split, search your String for key value pairs: \$(?<key>[^=]++)=\{(?<value>[^}]++)\} For example: final Pattern pattern = Pattern.compile(“\\$(?<key>[^=]++)=\\{(?<value>[^}]++)\\}”); final String input = “$key1={331015EA261D38A7}\n$key2={9145A98BA37617DE}\n$key3={EF745F23AA67243D}”; final Matcher matcher = pattern.matcher(input); final Map<String, String> parse = new HashMap<>(); while (matcher.find()) { parse.put(matcher.group(“key”), matcher.group(“value”)); } //print values parse.forEach((k, v) -> System.out.printf(“Key ‘%s’ has value ‘%s’%n”, k, v)); Output: Key ‘key1’ … Read more
First your json is invalid. Here is the same one but with fixes. {“data”:[{“name”:”123″,”pwd”:123},{“name”:”456″,”pwd”:456},{“name”:”789″,”pwd”:789}],”duration”:5309,”query”:”myquery”,”timeout”:300} And with this json model should look like this: public class Rootobject { public Datum[] data { get; set; } public int duration { get; set; } public string query { get; set; } public int timeout { get; set; } … Read more
A couple of comments/nitpicks, which may or may not solve your problem 🙂 if (!str || !(*str)) return NULL; Don’t do that. Don’t return NULL on empty strings, fputs() will barf. In my experience, it’s better to a) assert that the str pointer is non-null, b) return the empty string. begin=str+strlen(str)+1; *begin=’\0′; //?? There should … Read more
