🐍 Python Tip of the Day: Importing an Entire Module

How do you bring an entire module into your Python code?

You simply use the:

import module_name

Example:

import math

print(math.sqrt(25))  # Output: 5.0

This way, you're importing the *whole module*, and all its functions are accessible using the module_name.function_name format.

⚠️ Don’t Confuse With:

- from module import *
→ Brings *all* names into current namespace (not the module itself). Risky for name conflicts!

- import all or module import
→ Not valid Python syntax!

---

✅ Why use import module?
- Keeps your namespace clean
- Makes code more readable and traceable
- Avoids unexpected overwrites

🚀 How to Call a Parent Class Method from a Child Class in Python?

Let's dive in and answer this popular interview-style question! 👨‍💻👩‍💻

---

🔥 Question:
How can you call a method of the parent class from within a method of a child class?

---

✅ Correct Answer:
Option 1: Using the super() function

👉 Why?
- In Python, super() is the standard way to access methods and properties of a parent class from inside a child class.
- It's clean, elegant, and also supports multiple inheritance properly.

---
✅ Quick Example:

class Parent:
    def greet(self):
        print("Hello from Parent!")

class Child(Parent):
    def greet(self):
        print("Hello from Child!")
        super().greet()  # Calling parent class method

# Create an instance
child = Child()
child.greet()

🛠 Output:

Hello from Child!
Hello from Parent!

---

🔥 Let's Review Other Options:
- Option 2: Directly calling parent method (like Parent.greet(self)) is possible but not recommended. It tightly couples the child to a specific parent class name.
- Option 3: Creating an instance of the parent class is incorrect; you should not create a new parent object.
- Option 4: parent_method() syntax without reference is invalid.

---

🎯 Conclusion:
✅ Always use super() inside child classes to call parent class methods — it's the Pythonic way! 🐍✨

🔥 Simple Explanation:
- In Python, we use the class keyword to define any class (whether it's a base class or a child class).
- There’s no keyword like inherit, superclass, or parent in Python.
- inherit means "to inherit," but it's not a Python keyword.
- superclass and parent are just concepts, not keywords.

---

✅ A Simple Example:

class Animal:
    pass

class Dog(Animal):
    pass

🔹 Here:
- Animal is a base class (or parent class).
- Dog is a child class that inherits from Animal.

And for both, the class keyword is used! 🎯

---
🎯 Conclusion:
✅ So, always use class to define any class in Python (whether it's a parent or child class).
