In the example, we go through the set and print its elements one by one. $ ./python_set_iteration.py table cup coin spring bottle Python set addThe Python set add method adds a new element to the set. python_set_add.py #!/usr/bin/python words = { "spring", "table", "cup", ...
Typical usage of iteration in reverse: it := list.Iterator() for it.End(); it.Prev(); { index, value := it.Index(), it.Value() ... } Other usages: if it.Last() { lastIndex, lastValue := it.Index(), it.Value() ... } ReverseIteratorWithKey An iterator whose elements are...

They reject duplicate elements at creation time. Duplicate elements passed to a static factory method result inIllegalArgumentException. The iteration order of set elements is unspecified and is subject to change. They arevalue-based. Callers should make no assumptions about the identity of the retu...
You can evaluate a QuerySet in the following ways: Iteration. A QuerySet is iterable, and it executes its database query the first time you iterate over it. For example, this will print the headline of all entries in the database: for e in Entry.objects.all(): print(e.headline) No...
In [58]: dataset = [i for i in range(10)] dataloader = DataLoader(dataset=dataset, batch_size=3, shuffle=True) for i, item in enumerate(dataloader): # 迭代输出 print(i, item) 1. 2. 3. 4. 5. 6. 0 tensor([3, 1, 2]) ...
In every iteration, the suitable result of each ant is spread rapidly among its neighbors. In the next iteration because of this positive feedback, a purposive path that is closer to the optimal solution can be found. The convergence process speeds up due to this smart behavior. Hence the ...
This class implements theSetinterface, backed by a hash table (actually aHashMapinstance). It makes no guarantees as to the iteration order of the set; in particular, it does not guarantee that the order will remain constant over time. This class permits thenullelement. ...

Mandelbrot set - a set of complex numbers that has a highly convoluted fractal boundary when plotted; the set of all points in the complex plane that are bounded under a certain mathematical iteration mathematical space, topological space - (mathematics) any set of points that satisfy a set of...
