Write a Python program to print the following pattern 'S'.

Pictorial Presentation:

Sample Solution:

Python Code:

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

# Loop through rows from 0 to 6 using the range function
for row in range(0, 7):
    # Loop 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 (((row == 0 or row == 3 or row == 6) and column > 1 and column < 5) or 
            (column == 1 and (row == 1 or row == 2 or row == 6)) or 
            (column == 5 and (row == 0 or row == 4 or row == 5))):
            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 for the first shape
print(result_str)

# Define variables 'row' and 'col' with values 15 and 18 respectively
row = 15    
col = 18   
result_str = ""  # Reinitialize the 'result_str' to an empty string

# Loop through values from 1 to 'row' using the range function
for i in range(1, row+1):
    # Check conditions to determine the pattern for each row
    
    # If conditions are met, append 'o' to the 'result_str' in specific positions
    if ((i <= 3) or (i >= 7 and i <= 9) or (i >= 13 and i <= 15)):
        for j in range(1, col):
            result_str = result_str + "o"  # Append 'o' to the 'result_str'
        result_str = result_str + "\n"  # Add a newline character after each row in 'result_str'
    elif (i >= 4 and i <= 6):
        for j in range(1, 5):
            result_str = result_str + "o"  # Append 'o' to the 'result_str'
        result_str = result_str + "\n"  # Add a newline character after each row in 'result_str'
    else:
        for j in range(1, 14):
            result_str = result_str + " "  # Append space (' ') to the 'result_str'
        for j in range(1, 5):
            result_str = result_str + "o"  # Append 'o' 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 for the second shape
print(result_str)
