1. Tuple unpacking and decompression sequence assignment  Any sequence (or an iterative object) can be extracted and assigned to multiple variables by a simple assignment statement. The only prerequisite is that the number of variables must be the same as the number of elements in the sequence.  1. Parallel Assignment:>>> x = (1, 2>>> A, b = x #>>> a1>>> b 22. Use the * operator to disassemble an iterative object as a function parameter:>>> Divmod (8) # 20 for the remainder of 8, 2 * 8 + 4

operation time complexity is O (log N), where n is the size of the heap, so even when N is very large, they are still running fast. In the above code, the queue contains a tuple (-priority, index, item). The goal of a negative priority is to make the element sort from highest to lowest priority. This sort of heap is the opposite of regular sort by priority from low to high. The role of the index variable is to ensure that the same priority elements are sorted correctly. By saving an ever-increa
