Master Python Patterns – Create Pyramids and Patterns with Code

This article will review different ways to generate pyramids and patterns in Python. Let’s Master Python Patterns – Create Pyramids and Patterns with Code.

Half pyramid of asterisks

def half_pyramid(rows): 
    for i in range(rows):
        print('*' * (i+1))

half_pyramid(6)

Output

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

An alternate way to generate half pyramid using nested loops in Python.

Program

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

half_pyramid(6)

Output

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

Half pyramid of X’s

def half_pyramid(rows): 
    for i in range(rows):
        print('X' * (i+1))

half_pyramid(6)

Output

X
XX
XXX
XXXX
XXXXX
XXXXXX

Half pyramid of numbers

def half_pyramid(rows): 
    for i in range(rows):
        for j in range(i + 1):
            print(j + 1, end="")
        print("")

half_pyramid(5)

Output

1 
12 
123 
1234 
12345

Generating a full pyramid of asterisks

def full_pyramid(rows): 
    for i in range(rows): 
        print(' '*(rows-i-1) + '*'*(2*i+1))

full_pyramid(6)

Output

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

Full pyramid of X’s

def full_pyramid(rows): 
    for i in range(rows): 
        print(' '*(rows-i-1) + 'X'*(2*i+1)) 

full_pyramid(6)

Output

     X
    XXX
   XXXXX
  XXXXXXX
 XXXXXXXXX
XXXXXXXXXXX

Reversed pyramid

def inverted_pyramid(rows): 
    for i in reversed(range(rows)):
        print(' '*(rows-i-1) + '*'*(2*i+1))

inverted_pyramid(6)

Output

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