Building a tower of in python

Building a tower in Python can be achieved in multiple ways. In this article, we will explore three different approaches to solve this problem. Each approach will be explained in detail, accompanied by sample code and divided into sections using

tags.

Approach 1: Using nested loops

This approach involves using nested loops to print each row of the tower. We start with a base size and increment the number of asterisks in each row until we reach the desired height of the tower.


def build_tower(height):
    for i in range(height):
        for j in range(height - i - 1):
            print(" ", end="")
        for j in range(2 * i + 1):
            print("*", end="")
        print()

build_tower(5)

This code will output a tower with a height of 5:

    *
   ***
  *****
 *******
*********

Approach 2: Using string manipulation

In this approach, we build each row of the tower as a string and concatenate them to form the complete tower. We use string manipulation techniques to add spaces and asterisks in each row.


def build_tower(height):
    tower = ""
    for i in range(height):
        spaces = " " * (height - i - 1)
        asterisks = "*" * (2 * i + 1)
        tower += spaces + asterisks + "n"
    return tower

print(build_tower(5))

This code will output the same tower as in Approach 1:

    *
   ***
  *****
 *******
*********

Approach 3: Using recursion

In this approach, we use recursion to build the tower. We define a recursive function that calls itself with a smaller height until the base case is reached. The base case is when the height is 0, in which case we return an empty string. We then concatenate the spaces and asterisks for each row to form the tower.


def build_tower(height):
    if height == 0:
        return ""
    spaces = " " * (height - 1)
    asterisks = "*" * (2 * (height - 1) + 1)
    return build_tower(height - 1) + spaces + asterisks + "n"

print(build_tower(5))

This code will also output the same tower as in Approach 1 and 2:

    *
   ***
  *****
 *******
*********

After exploring these three approaches, it is clear that Approach 2, using string manipulation, is the most efficient and concise solution. It avoids the complexity of nested loops and the overhead of recursion. Therefore, Approach 2 is the recommended option for building a tower in Python.

  1. I personally prefer Approach 2: Using string manipulation for building the tower. Its more concise and efficient.
