Hello everyone! Welcome back to programminginpython.com, here in this post I am going to show you how to print a pattern of Letter C.

This is a continuation of the letter pattern printing series, in the previous tutorials I have explained the patterns of Letter A and Letter B.

Task:

Python program to print the pattern of letter ‘C’

Approach:

• Read an input integer for asking the size of the letter using  input()
• Check if the entered number is greater than 8,
  • if yes, call the function `print_pattern()`
  • else, show a message to enter a number that 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 ‘C’
  • following are 3 conditions for printing *’s
    We have 2 loops, an outer loop() for rows and an inner loop for columns

    # Outer for loop
    for i in range(n): 
        # Inner for loop 
        for j in range(n + 1):

    1. 1. the first line of alphabet
          i == 0
       2. last line
          i == n - 1
       3. first column
          j == 0 and (i != 0 and i != n - 1)
  • print ` ` in remaining all cases.

# Python3 program to print alphabet pattern C

# 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 logic execution
        for j in range(n + 3):
            # Print 1st line
            if ((i == 0 or
                 # Print last line
                 i == n - 1) and
                    # For more reasonable curve
                    j > 0 or
                    # First column
                    (j == 0 and (i != 0 and i != n - 1))):
                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 minimum of 8")

Output:
