6. Decorators - 6
1. Chain two decorators with the greet function as shown in the following code.
2. Run the code and verify if the HTML tags have been added on both sides of the string.
@bold_tag @italic_tag def greet(): return input()
3. Use the Test against custom input box to output the result for debugging.
4. Provide a string (refer test case samples) to display the output/error.

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
