Python Program to Print Star Pattern

Star pattern programs in python; In this tutorial, you will learn how to implement programs in python to print star pattern using for loop, while loop and function.

Python Program to Print Star Pattern

Let’s follow the following python program to print the different types of star pattern; as shown below:

• Programs for printing pyramid patterns in Python usng Function
• Inverted star pattern in python using For Loop
• Program to print inverted half pyramid
• Python program to print Asterisk pattern
• Python program to print pyramid
• Python program to print inverted pyramid pattern

1: Programs for printing pyramid patterns in Python using Function

# Python Program to print star pattern

# Function to demonstrate printing pattern
def pyramid (n):

    # outer loop to handle number of rows
    # n in this case
    for i in range(0, n):

        # inner loop to handle number of columns
        # values changing acc. to outer loop
        for j in range(0, i+1):

            # printing stars
            print("* ",end="")

        # ending line after each row
        print("\r")

# Driver Code
n = 5
pyramid(n) 

Output

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

2: Inverted star pattern in python using For Loop

# python Program print inverted star

n=11


for i in range (n, 0, -1):
    print((n-i) * ' ' + i * '*') 

Output

3: Program to print inverted half pyramid

rows = 6

for i in range (rows,0,-1):
    for j in range(0, i + 1):
        print("*", end=' ')

    print("\r")

Output

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

4: Python program to print Asterisk pattern

rows = 5
for i in range (0, rows):
    for j in range(0, i + 1):
        print("*", end=' ')
    print("\r")

for i in range (rows, 0, -1):
    for j in range(0, i -1):
        print("*", end=' ')
    print("\r")

Output

5: Python program to print pyramid

def full_pyramid(rows):

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

full_pyramid(5)

Output

6: Python program to print inverted pyramid pattern

def inverted_pyramid(rows):

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

inverted_pyramid(5)

Output
