Python Program to Print Q Star Pattern

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

The below alphabet Q star pattern example accepts the user-entered rows, and the nested for loop iterates the rows. The elif condition is to print stars on the four sides and an extra tail to get the Alphabetical Q pattern of stars and skip others.

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

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

Enter Alphabet Q of Stars Rows = 9

The above code uses the elif condition to prints the Alphabet Q pattern of stars; the below code use the If else condition is to print stars.

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

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

Python program to print the Alphabet Q Star pattern using while loop

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

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

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

Enter Alphabet Q of Stars Rows = 12

In this Program example, we created a QPattern function that accepts the rows and the symbol or character to print the Alphabet Q pattern of the given symbol.

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


row = int(input("Enter Alphabet Q of Stars Rows = "))
sy = input("Symbol for Q Star Pattern = ")
QPattern(row, sy)

Enter Alphabet Q of Stars Rows = 14
