# Python3 program to demonstrate working of heapq
  
from heapq import heapify, heappush, heappop
  
# Creating empty heap
heap = []
heapify(heap)
  
# Adding items to the heap using heappush function
heappush(heap, 10)
heappush(heap, 30)
heappush(heap, 20)
heappush(heap, 400)
  
# printing the value of minimum element
print("Head value of heap : "+str(heap[0]))
  
# printing the elements of the heap
print("The heap elements : ")
for i in heap:
    print(i, end = ' ')
print("
")
  
element = heappop(heap)
  
# printing the elements of the heap
print("The heap elements : ")
for i in heap:
    print(i, end = ' ')
