25. Alphabet Pattern 'R'

Write a Python program to print the alphabet pattern 'R'.

Pictorial Presentation:

Sample Solution:

Python Code:

# Initialize an empty string named 'result_str'
result_str = ""

# Iterate through rows from 0 to 6 using the range function
for row in range(0, 7):
    # Iterate through columns from 0 to 6 using the range function
    for column in range(0, 7):
        # Check conditions to determine whether to place '*' or ' ' in the result string
        
        # If conditions are met, place '*' in specific positions based on row and column values
        if (column == 1 or ((row == 0 or row == 3) and column > 1 and column < 5) or (column == 5 and row != 0 and row < 3) or (column == row - 1 and row > 2)):
            result_str = result_str + "*"  # Append '*' to the 'result_str'
        else:
            result_str = result_str + " "  # Append space (' ') to the 'result_str'

    result_str = result_str + "\n"  # Add a newline character after each row in 'result_str'

# Print the final 'result_str' containing the pattern
print(result_str)

 *  *
