Syntax error Python Program for Tower of Hanoi

Python Program for Tower of Hanoi



In this article, we will learn about the solution to the problem statement given below.

Problem statement − We are given n disks and a series of rods, we need to transfer all the disks to the final rod under the given constraints−

  • We can move only one disk at a time.

  • Only the uppermost disk from the rod can be moved.

  • Any bigger disk cannot be placed on the smaller disk

Now let’s observe the solution in the implementation below −

Example

 Live Demo

# tower of hanoi
def TowerOfHanoi(n , from_rod, to_rod, aux_rod):
   if n == 1:
      print ("Move disk 1 from rod",from_rod,"to rod",to_rod)
      return
   TowerOfHanoi(n-1, from_rod, aux_rod, to_rod)
   print ("Move disk",n,"from rod",from_rod,"to rod",to_rod)
   TowerOfHanoi(n-1, aux_rod, to_rod, from_rod)
# main
n = 3
TowerOfHanoi(n, 'A', 'C', 'B')
# A, B, C are the rod
print ("Sorted array is:")
for i in range(n):
   print (arr[i],end=" ")

Output

Move disk 1 from rod A to rod C
Move disk 2 from rod A to rod B
Move disk 1 from rod C to rod B
Move disk 3 from rod A to rod C
Move disk 1 from rod B to rod A
Move disk 2 from rod B to rod C
Move disk 1 from rod A to rod C

All the variables are declared in the local scope and their references are seen in the figure above.

Conclusion

In this article, we have learned about how we can make a Python Program for Tower of Hanoi
