+- [ ] This pull request does not contain any breaking change.
+- [ ] I asked [the AI](https://copilot.microsoft.com/) to briefly summarize, use and improve the feature(s), and I'm okay with the output:
+<!-- ⇅ remove it if it doesn't make sense ⇅ -->
+<!-- ↓ here belongs the AI inputs (>>) and outputs (>) ↓ -->
+>> Could you briefly summarize the following code for me?
+>> ```python
+>> class Tiger:
+>>    def __init__(self, name):
+>>       self.name = name
+>>
+>>    def roar(self):
+>>       print(f"{self.name} lets out a powerful roar!")
+>> ```
+>
+> This code defines a Python class named `Tiger` with a constructor that initializes the tiger's name, and a `roar` method that prints a message including the tiger's name. Simple and elegant, just like a tiger! 🐅
+>
+>> Could you show me how to use it?
+>
+> Sure, here's how to create and use a `Tiger` object with the class you have:
+> ```python
+> # Create an instance of Tiger
+> my_tiger = Tiger("Gopal")
+> 
+> # Call the roar method
+> my_tiger.roar()
+> ```
+>
+> When you run this code, it will output:
+> ```
+> Gopal lets out a powerful roar!
+> ```
+>
+> That's how you bring your Tiger to life! 🎉
+>
+>> Is there any way to do it better?
+>
+> Absolutely. You could add error handling, additional methods, or even inheritance. Here's an enhanced version:
+> ```python
+> class Tiger:
+>     def __init__(self, name):
+>         self.name = name
+> 
+>     def roar(self):
+>         print(f"{self.name} lets out a powerful roar!")
+> 
+>     def introduce(self):
+>         print(f"Meet {self.name}, the majestic tiger!")
+>
+> # Usage
+> my_tiger = Tiger("Gopal")
+> my_tiger.introduce()  # Output: Meet Gopal, the majestic tiger!
+> my_tiger.roar()  # Output: Gopal lets out a powerful roar!
+> ```
+>
+> Now your tiger can introduce itself, too. 🐯📢
