Write a Python Program to Create Pyramid Patterns

In this tutorial, we will be learning how to create pyramid patterns using Python.

A pyramid pattern is a series of numbers or characters arranged in a triangular shape, such that each row of the triangle has one more element than the row above it.

The pattern can be oriented in different ways, depending on the desired output.

Pyramid patterns are commonly used in computer programming for various purposes such as printing output, creating games, and many more.

Python provides several ways to create pyramid patterns.

Here, we will explore three different methods:

Using nested for loops

The nested for loop is a simple and straightforward way to create pyramid patterns in Python.

The outer loop controls the number of rows in the pattern, while the inner loop controls the number of characters in each row.

Here’s an example of creating a pyramid pattern using nested for loops:

# program to create pyramid pattern using nested for loops

n = 5  # number of rows

for i in range(n):
    for j in range(i+1):
        print("*", end="")
    print()

Output:

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

Using string concatenation

String concatenation is another way to create pyramid patterns in Python.

In this method, we use the ‘+’ operator to concatenate strings and create the pattern.

Here’s an example of creating a pyramid pattern using string concatenation:

# program to create pyramid pattern using string concatenation

n = 5  # number of rows

for i in range(n):
    print(" "*(n-i-1) + "*"*(2*i+1))

Output:

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

Using recursion

Recursion is a powerful technique for creating pyramid patterns in Python.

In this method, we create a function that calls itself recursively to generate the pattern.

Here’s an example of creating a pyramid pattern using recursion:

# program to create pyramid pattern using recursion

def pyramid(n):
    if n == 0:
        return
    pyramid(n-1)
    print("*" * n)

n = 5  # number of rows
pyramid(n)

Output:
