Python: Push three items into the heap and print the items from the heap
21. Push Three Items to Heap
Write a Python program to push three items into the heap and print the items from the heap.
Sample Solution:
Python Code:
import heapq
heap = []
heapq.heappush(heap, ('V', 1))
heapq.heappush(heap, ('V', 2))
heapq.heappush(heap, ('V', 3))
for a in heap:
print(a)
Sample Output:
('V', 1)
('V', 2)
('V', 3)
