We have to use the heapq.heapify() module to create the heapq data structure in a sorted order. Then we have to create a list ( using iterable object) and use the heapq.heapify() module. Here, we have to first import the heapq module. Using heapq module, programmers can perform both push and pop operations simultaneously using the heapq.heappushpop(heap, elem) method. Heap Push and Pop operation simultaneously: The second one is the element value that will replace the smallest element from the heapq. Here we have to pass two parameters, the first one denotes the heapq object where new element will get inserted. Then we use the heapreplace() method to replace an element with a new one. Then we have to create a list (using iterable object) and use the heapq.heapify() module. The heapreplace() method helps in removing the smallest element of the heapq and brings in a new element at some place not defined by any order in that heapq. Then we print the result using print() function. After pushing 58, we will use the heappop() method that will pop out one element from the first index location. Any element residing at index 1 will get popped out automatically from the heapq. Programmers can eliminate any element residing at the first index using the heappop() function. The second one is the element value that will be inserted. Then we have used the heapq.heappush(itrObj, 58) and passed two parameters, the first one denotes the heapq object where new element will get inserted. Print("New set of values after inserting a value in the heapq are:", itrObj) But, as we know now that we can use the heapify() method to bring any newly inserted element to a proper order if it is smaller than any of the existing value. Inserting elements in the heap:Īdding any new data element to a heap helps in inserting that specific element at the last index of the heapq. Then, we will use the print() function to display it. Then we have to create a list (iterable object) and use the heapq.heapify() module to create the heapq data structure in a sorted order. Print("The sorted set of values are:", itrObj) Heapq.heapify(itrObj) #heapq created using iteracble object # heapify() for creating and rearranging the elements heappushpop(): This method is equivalent to a heappush() operation followed by a heappop() operation.heapreplace(heap, elem): This method helps in replacing the smallest element within the heap with a new value provided within the method as a parameter.heappop(heap): This method helps in removing and returning the smallest value from the heap.heappush(heap, elem): This method helps in inserting the element mentioned within its arguments of the heap. It performs the conversion in heap order.
