Sorry but that day I didn’t know about slicing, sorry to bother, here it is: l=[1,2,3,4,5,6,7,8,9];l=[[l[i],l[i+1],l[i+2]] for i in range(0,9,3)];print(L) solved How to print a list as list of list in particular order in Python?
I guess you want to stop the execution of the setInterval, for that you could return the setInterval’s result from the function and pass it to a clearInterval to avoid it’s execution. For this, you might also have to add a check to see if the function has been started or not But for now, … Read more
You can use this sample code: function createDataValidation() { var ss = SpreadsheetApp.getActiveSpreadsheet(); var s1 = ss.getSheetByName(“Sheet1”); var s2 = ss.getSheetByName(“Sheet2”); var s2_lastRow = s2.getLastRow(); //create data validation per row for (var row = 1; row <= s2_lastRow; row++){ //create an a1Notation to select a complete row sample: “A1:1”, “A2:2”, and so on. var a1Notation … Read more
You’d better use other frameworks other than OpenCV. OpenCV is extremely heavy for this kind of job. It’s mainly focused on image processing. Maybe you can use OpenImageIO, freeimage or other libs. You can refer to these posts: Reading an image file in C/C++ https://products.fileformat.com/image/cpp/openimageio solved How to build opencv that only support decode jpeg?
here I m showing you a method which will accept a number list and using that list, it will provide new List. New list will take care of Alphabetical order of number No duplicate numbers No recurring numbers you will only need to check your rate’s part of logic to elemental those numbers who have … Read more
If you want [{‘name’: ‘None’, ‘age’:20, ‘dead’:’NO’}] then try: data_dict = {‘name’: ‘None’, ‘age’:20, ‘dead’:’NO’} data_list =[data_dict] 7 solved How to insert a dictionary inside list [closed]
If instead of copying all bytes in A, you only copy the number of bytes that B expects, you will achieve your desired result: memcpy(&v2, &v1, sizeof(v2)); // remember that the first argument is the destination However, this is not good coding style. With this minimal code example, it is hard to tell, but you … Read more
this looks like a implementation to test the https://en.wikipedia.org/wiki/Collatz_conjecture if a number is even, its divided by 2, if its odd, its multiplied by 3 and 1 is added. the conjecture aussumes it will lead to 1 for each positive integer, but there is no proof yet solved I need help understanding what the following … Read more
I think when you run your program then edit text have no value that means it will return NULL and NULL can’t be a Integer value so you must have to check Condition Like String editTextValue = number.getText().toString(); if(!TextUtils.isEmpty(editTextValue)){ angka = Integer.parseInt(editTextValue); } I hope its work for you. 3 solved Getting a value of … Read more
Here is an example of reading and writing a text file below. I believe that you are looking for the “open” method. with open(‘New_Sample.txt’, ‘w’) as f_object: f_object.write(‘Python sample!\n’) f_object.write(‘Another line!\n’) You simple open the file that you want and enter that file name as the first argument, and then you use ‘w’ as the … Read more
The error is self-explanatory. You are not passing in the correct parameters that decode() is expecting. Look at the actual declaration of the decode() overload that you are trying to call (there are 3 overloads available): unsigned decode(std::vector<unsigned char>& out, unsigned& w, unsigned& h, const std::string& filename, LodePNGColorType colortype = LCT_RGBA, unsigned bitdepth = 8); … Read more
I was able to solve the problem by pre processing the data to store the person’s timezone. Then using pytz I do this. from django.utils import timezone import pytz valid_timezones = [] for tz in list_of_timezones: local_time = now().astimezone(pytz.timezone(tz)) if 19 < local_time.hour < 20: valid_timezones.append(tz) reminders = Person.objects.filter(timezone__in=valid_timezones) solved How to filter Django queryset … Read more
The solution is the data cutting between {}. Try this: $result = preg_replace(“#\{img:(.*)\}#U”,'<img src=\’$1\’ style=\’width:100%\’ />’,$content); 0 solved Match content between parenthesis and get the url and change it to img tag using RegExp PHP [duplicate]
It appears to me that within your list comprehension you just have one minor issue! Instead of: item for item in textString within your list comprehension, I would suggest: item for item in listText as currently you are iterating through each char of the whole text, rather than each element in the list of the … Read more
The problem is you assign an empty array every time you call the function radioButtonVal = (e) => { this.radioid = e.target.name; this.radiovalue = e.target.value; this.radioButtonValTitles = []; //right here you initiate an empty array this.radioButtonValFind = this.radioButtonValTitles.find(x => x.id === this.radioid); if(this.radioButtonValFind){ this.radioButtonValFind.id = this.radioid; this.radioButtonValFind.value = this.radiovalue; } else { this.radioButtonValTitles.push({id: this.radioid, value: … Read more
