您可以在“/”上拆分键,并且只保留第一级: level1 = set() #Using a set removes duplicates automatically for key in s3_client.list_objects(Bucket='bucketname')['Contents']: level1.add(key["Key"].split("/")[0]) #Here we only keep the first level of the key #then print your level...

String: If the array is an array of objects, you can sort the array by the value of one of the object properties. See the examples below. Function: You can create a function to organize the sorting. Array: Use an array if you need more than one object property to determine the sortin...
{ var self = this; // Initialize our grid for (var x = 0; x < service.size * service.size; x++) { this.grid[x] = null; } // Initialize our tile array // with a bunch of null objects this.forEach(function(x,y) { self.setCellAt({x:x,y:y}, null); }); }; // ....
Let’s say we have an array of objects with a color field. $scope.items = [{ color: 'red' }, { color: 'green' }, { color: 'blue' }] Again, we can use ngRepeat to loop through them. This time we’ll incorporate a built-in filter to sort by that color field. {{ item...
Right, there is no data in the table by default. To add some, let's create an array property with a list of objects in the component. Please note that object keys are the same as in the columns configuration. data = [ { id: 1, name: "Leanne Graham", username: "Bret", email: ...
Angular中的ng-repeat指令用于在HTML模板中循环显示数据。在ng-repeat中,可以使用track by子句来指定一个唯一的标识符,以便Angular能够跟踪和更新循环中的每个项目。...
