Python Program to Print Alphabet W Pattern of Stars

This article shows how to write a Python program to print the Alphabet W star pattern using the for loop, while loop, and functions with an example. 

The below alphabet W star pattern example accepts the user-entered rows, and the nested for loop iterates the rows. The If else condition is to print stars at the required positions to get the Alphabetical W pattern of stars and skip others.

rows = int(input("Enter Alphabet W of Stars Rows = "))
print("====The Alphabetical W Star Pattern====")

for i in range(rows):
    for j in range(rows):
        if j == 0 or j == rows - 1:
            print("*", end=" ")
        elif (i + j == rows - 1 or i == j) and i >= rows // 2:
            print("*", end=" ")
        else:
            print(" ", end=" ")
    print()

Python program to print the Alphabet W pattern of Stars using while loop

Instead of a For loop, this program uses the while loop to iterate the Alphabet W pattern rows and prints the stars at a few positions. For more Star Pattern programs >> Click Here. 

rows = int(input("Enter Alphabet W of Stars Rows = "))

i = 0
while i < rows:
    j = 0
    while j < rows:
        if j == 0 or j == rows - 1:
            print("*", end="")
        elif (i + j == rows - 1 or i == j) and i >= rows // 2:
            print("*", end="")
        else:
            print("", end=" ")
        j += 1
    print()
    i += 1

Enter Alphabet W of Stars Rows = 10

In this Python example, we created a WPattern function that accepts the rows and the symbol or character to print the Alphabet V pattern of the given symbol.

def WPattern(rows, ch):
    for i in range(rows):
        for j in range(rows):
            if j == 0 or j == rows - 1:
                print('%c' %ch, end=' ')
            elif (i + j == rows - 1 or i == j) and i >= rows // 2:
                print('%c' %ch, end=' ')
            else:
                print(" ", end=" ")
        print()


row = int(input("Enter Alphabet W of Stars Rows = "))
sy = input("Symbol for W Star Pattern = ")
WPattern(row * 2 + 1, sy)

Enter Alphabet W of Stars Rows = 8
