In your source code there are two main problems: You use the same id value many times. According to HTML documentation the id is used as unique identificator for an element. You are “attaching” the circle to <svg> and not to <g> tag with the svg.appendChild(shape); You can do something similar to: var svgElem = … Read more
With the new example, you’re actually still dealing with tuples. If you print out what the right hand side is, you’ll get testVar = 1000, 1000, print(testVar) # result: (1000,1000) What is actually happening under the hood is that Python sees a tuple, then unpacks it into two values and assigns one to myvar and … Read more
Calling functions from parent class directly is easy as the following: std::stringstream myobj; myobj << “Something…” myobj.std::iostream::flush(); Above example calls flush() directly from std::iostream (which is a typedef of std::basic_iostream<char> ). It is also possible to member functions from parent class of parent class: myobj.std::ostream::flush(); solved How to call functions from parent class in C++? … Read more
Given a non-empty list of strings of the same length, how do I create a list of lists of the letters at each position in the string without using zip? [closed] solved Given a non-empty list of strings of the same length, how do I create a list of lists of the letters at each … Read more
I’m offering two solutions. The first formats the input as Pascal Case. static void Main(string[] args) { Console.WriteLine(ToCamelCase(“camels-drink-LOTS-OF_WATER”)); Console.ReadKey(); } public static string ToCamelCase(string str) { // This holds our output StringBuilder sb = new StringBuilder(); // Step 1 – split input into array of words string[] res = str.Split(new char[] { ‘-‘, ‘_’ }, … Read more
((short *)((((char *)(&arr[1])) + 8))[3] = 100 &arr[1]: is the address of the second int in arr (1*sizeof(int) from start). ((char *)(&arr[1])) : converts int address to a char address (((char *)(&arr[1])) + 8) : adds 8 bytes to the char address ((short *)((((char *)(&arr[1])) + 8)): converts the char address to a short address … Read more
In order for two phones to detect each other with BLE beaconing you need them to do two things: Advertise a beacon over BLE Scan for beacons over BLE But flutter_beacon only does item 2 above. For item 1, you need another package. Try beacon_broadcast: https://pub.dev/packages/beacon_broadcast You need to do both at once. If you … Read more
Use x[1][“number”] in your lambda n [40]: d Out[40]: {‘b’: {‘description’: ‘second letter’, ‘number’: 2}, ‘a’: {‘description’: ‘first letter’, ‘number’: 1}, ‘c’: {‘description’: ‘third letter’, ‘number’: 3}} In [41]: sorted(d.items(), key=lambda x:x[1][“number”]) Out[41]: [(‘a’, {‘description’: ‘first letter’, ‘number’: 1}), (‘b’, {‘description’: ‘second letter’, ‘number’: 2}), (‘c’, {‘description’: ‘third letter’, ‘number’: 3})] 1 solved Sorting a … Read more
Given the tables: Tabel_1 idUnit Budget 112 1000 112 2000 Tabel_2 idUnit Real2 112 500 112 100 You can produce the following result: idUnit TotalBudget TotalReal2 112 3000 600 With the following query: SELECT t1.idUnit, SUM(Budget) AS TotalBudget, t2.TotalReal2 FROM Tabel_1 AS t1 JOIN (SELECT idUnit, SUM(Real2) AS TotalReal2 FROM Tabel_2 GROUP BY idUnit ) … Read more
Yes: let array = [“ABC”, “BCA”, “CDA”, “APA”] let array2 = [“ABC”, “APA”] const output = array.map((item) => { let isFound = array2.includes(item); return { value: item, matched: isFound }; }) console.log(output) 1 solved 2 arrays matchings , transformation in arrays of objects [closed]
Because these parameters are not being passed by reference, setting them to any value will only change the value of the parameter variables local to your helper method: it will not impact the values that were passed in to those parameters. Since you don’t use the new values you’re assigning to those parameters inside the … Read more
You could group by name, next count values and filter results which have count 3 (because you have 3 years) groups = df.groupby(‘name’).count() result = groups[ groups[‘date’] == 3 ].index.to_list() print(result) Or you could directly count names counts = df[‘name’].value_counts() result = counts[ counts == 3 ].index.to_list() print(‘result:’, result) Minimal working example: I use io.StringIO … Read more
Consider the following example using toUpperCase which is also an instance method. It works in this case because the Stream item that is being handled is of the same type as the class of the method being invoked. So the item actually invokes the method directly. So for Stream.of(“abcde”).map(String::toUpperCase).forEach(System.out::println); the String::toUpperCase call will be the … Read more
I have the correct answer for that. When inviting a bot to any server, there is special 2Oauth link for inviting the bot. Now, this is something you need to worry about.
