Python Decorators - 3 - Hands On
3. Decorators - 3
1. Define a decorator function bold_tag which adds bold HTML tags function. to the value of another
2. Use the Test against custom input box to output the result for debugging.
3. Provide a string (refer test case samples) to display the output/error.

<b>Decorator exercise</b>
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.
