Python Program to print pattern of letter A

Hello everyone! Welcome back to programminginpython.com. I am continuing with this pattern programming series, here I will tell you how to print the pattern of the letter A.

Also, I will try to display the patterns for all other alphabets later in this series.

You can also watch the video on YouTube here.

Task:

Python program to print the pattern of letter ‘A’

Approach:

  • Read an input integer for asking the sizeof the letter using  input()
  • Check if the enter number is greater than 8,
    • if yes, call the function `print_pattern()`
    • else, show a message to enter number which is greater or equal to 8
  • print_pattern()
    • here we only do two things, print star(*) and print space(` `), just writing conditions so the pattern of *‘s and ` `’s will display the pattern ‘A’
    • following are 3 conditions for printing *’s
      We have 2 loops, outer loop() for row’s and inner loop for columns.

      # Outer for loop
        for i in range(n): 
            # Inner for loop 
            for j in range((n // 2) + 1):
    • every line – at the start and end
    • (j == 0 or j == n //2) and i != 0
    • middle line – the whole line
      i == n // 2
    • first line – whole line except first and last row
      i == 0 and j != 0 and j != n // 2
    • print ` ` in remaining all cases.

# Python3 program to print alphabet A pattern 

# Function to display alphabet pattern 

def print_pattern(n): 
    # Outer for loop for number of lines(rows) 
    for i in range(n): 
        # Inner for loop for printing *'s and  &nbsp's(columns) 
        for j in range((n // 2) + 1): 
            # prints two column lines 
            if ((j == 0 or j == n //2) and i != 0 or
                # print first line of alphabet
                i == 0 and j != 0 and j != n // 2 or
                # prints middle line 
                i == n // 2): 
                print("*", end = "") 
            else: 
                print(" ", end = "")
        print() 

# Size of the letter

num = int(input("Enter the size: \t "))
if num > 7:
    print_pattern(num)
else:
    print("Enter a size minumin of 8")
