1⃣ A class MyClass is defined with a method method_not_implemented_yet that is not yet implemented and uses pass.
2⃣ A function my_function is defined that is not yet implemented and uses pass.
3⃣ In a for loop, when the value of i is 3, pass is used to indicate that no action is taken in this case, but the loop continues its execution.
✅The pass statement allows you to maintain the structure of your code without syntactic errors, even if some parts of the code are not yet implemented.

❤️The pass statement in Python is used as a placeholder to indicate that a block of code or a function is intentionally left empty or not yet implemented.
❤️ It serves as a syntactic requirement in situations where a statement is expected but no action is necessary.

1⃣ A variable x is defined and then deleted using del.
2⃣ An element from the list my_list is deleted using its index.
3⃣ A slice from the list my_list is deleted using del.
4⃣An attribute attr1 from the object obj of the class MyClass is deleted.
✅The del statement allows you to remove unnecessary variables, items, and attributes from memory, which can help in memory management and optimizing the performance of your program.

What is the purpose of the 'del' statement in Python?
❤️The del statement in Python is used to delete a variable, an item from a list, or a slice from a list.
❤️This statement frees the memory space occupied by the variable or item, allowing it to be reclaimed by the system.
❤️Additionally, it can be used to delete attributes from objects and elements from lists.

1⃣ The with statement is used to open a file named example.txt in write mode ('w'). This ensures that the file is automatically closed once the block of code is exited, even if an exception occurs.
2⃣ Content is written to the file inside the with block.
3⃣Another with statement is used to open the same file in read mode ('r'). Again, this ensures that the file is properly closed after reading its content.
✅Using the with statement in this way provides a clean and efficient approach to working with external resources, ensuring they are properly managed and cleaned up, without needing explicit calls to close() or handling exceptions for file closure.

❤️The with statement in Python is used to define a context manager for resource management.
❤️It ensures that certain operations are properly initialized and cleaned up when working with resources such as files, database connections, or locks.
❤️ It provides a more concise and readable way to handle resource management compared to using try-except-finally blocks.

1⃣ The Person class has an init method which takes name and age as parameters.
2⃣ When an instance of the Person class is created (person1), the init method is automatically called with the provided arguments.
3⃣ Inside the init method, the name and age attributes of the instance (self) are initialized.
4⃣ Finally, we access and print the initialized attributes of the person1 object.
✅ The init method allows for the proper initialization of object attributes and provides a way to set up the initial state of objects when they are created.
