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 column == 5) and row != 0 and row != 6) or ((row == 0 or row == 6) and column > 1 and column < 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
print(result_str)
