Printing pyramid patterns in Python

Patterns can be printed in python using simple for loops. First outer loop is used to handle number of rows and Inner nested loop is used to handle the number of columns. Manipulating the print statements, different number patterns, alphabet patterns or star patterns can be printed.
Some of the Patterns are shown in this article.

Simple pyramid pattern

# Python 3.x code to demonstrate star pattern 

# Function to demonstrate printing pattern 

def pypart(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

pypart(n) 

Output:

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

After 180 degree rotation

# Python 3.x code to demonstrate star pattern 

# Function to demonstrate printing pattern 

def pypart2(n): 

    # number of spaces 

    k = 2*n - 2

    # outer loop to handle number of rows 

    for i in range(0, n): 

        # inner loop to handle number spaces 

        # values changing acc. to requirement 

        for j in range(0, k): 

            print(end=" ") 

        # decrementing k after each loop 

        k = k - 2

        # 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

Printing Triangle

# Python 3.x code to demonstrate star pattern 

# Function to demonstrate printing pattern triangle 

def triangle(n): 

    # number of spaces 

    k = 2*n - 2

    # outer loop to handle number of rows 

    for i in range(0, n): 

        # inner loop to handle number spaces 

        # values changing acc. to requirement 

        for j in range(0, k): 

            print(end=" ") 

        # decrementing k after each loop 

        k = k - 1

        # 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

Number Pattern

# Python 3.x code to demonstrate star pattern 

# Function to demonstrate printing pattern of numbers 

def numpat(n): 

    # initialising starting number  

    num = 1

    # outer loop to handle number of rows 

    for i in range(0, n): 

        # re assigning num 

        num = 1

        # inner loop to handle number of columns 

            # values changing acc. to outer loop 

        for j in range(0, i+1): 

                # printing number 

            print(num, end=" ") 

            # incrementing number at each column 

            num = num + 1

        # ending line after each row 

        print("\r") 

# Driver code 

n = 5

numpat(n) 

Output:

1 
1 2 
1 2 3 
1 2 3 4 
1 2 3 4 5
