Congratulations on reaching the midway point of your Python learning journey! Today, it’s time to assess your understanding of the topics covered so far. Let’s design a set of questions that span the breadth of your Python knowledge:

Section 1: Basics and Setup

1. Setting Up Python:

   • What are the steps to install Python on your machine?
   • Mention two popular online Python editors.

2. Variables and Data Types:

   • Explain the difference between int, float, and string data types.
   • What is variable naming convention, and why is it important?

Section 2: Control Flow

3. Conditional Statements:

   • Write a Python code snippet using if, else, and elif to determine if a number is positive, negative, or zero.

4. Loops:

   • Provide examples of using both for and while loops in Python.
   • What is the purpose of the break statement in a loop?

Section 3: Data Structures

5. Lists and Tuples:

   • Differentiate between a list and a tuple.
   • Write code to add an element to a list and concatenate two tuples.

6. Dictionaries:

   • Explain the structure of a Python dictionary.
   • Write code to access a value from a nested dictionary.

Section 4: Functions

7. Function Basics:

   • Define a function named calculate_area that calculates the area of a rectangle.
   • What is the purpose of the return statement in a function?

8. Advanced Functions:

   • Explain the concept of default arguments in functions.
   • Write a function that takes a variable number of arguments.

Section 5: File Handling

9. Working with Files:
   • How do you open a file in Python for reading and writing?
   • Write code to read the contents of a text file and print them.

Section 6: Exception Handling

10. Handling Exceptions:
    • Demonstrate the use of try, except, else, and finally blocks.
    • Write code to handle a specific exception and a general exception.

Instructions:

• Answer each question with clear explanations and, when applicable, provide code snippets.
• Take your time and refer to your notes or the Python documentation if needed.
• This assessment is a self-evaluation, so focus on understanding the concepts.

After completing the assessment, take note of areas where you feel confident and areas that may need further review. It’s a great opportunity to identify your strengths and areas for improvement. Keep up the excellent work on your Python journey!
