29. Alphabet Pattern 'X'

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

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 (((column == 1 or column == 5) and (row > 4 or row < 2)) or 
            row == column and column > 0 and column < 6 or 
            (column == 2 and row == 4) or 
            (column == 4 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) 

Sample Output:

 *   *                                                                                                        
 *   *                                                                                                        
  * *                                                                                                         
   *                                                                                                          
  * *                                                                                                         
 *   *                                                                                                        
 *   *
