Programming exercise 4 - Operations with strings

📝 Overview

In this assignment, you will practice various methods for manipulating and formatting text in Python using the Thonny IDE. You will replicate examples from class and solve a short coding challenge.

⚙️ Instructions

Part 1: Class Examples

1. Open Thonny.
2. Create a new file and save it exactly as OperationsWithStrings.py.
3. For each string operation covered in the lecture slides, you must:

• Write a print() statement indicating the operation name (e.g., print("--- f-strings ---")).
• Copy the Python code examples from the slide into your file below that print statement.
• Important: Do NOT copy any Java code examples found in the slides. Only the Python code.

4. Run your code frequently to ensure each example works correctly.

Part 2: Coding Exercise

At the bottom of your OperationsWithStrings.py file, add a comment # --- CODING EXERCISE --- and solve the following problem:

The Scenario: You have received a raw data string containing a student's ID and name, but it is surrounded by unnecessary symbols. raw_text = "###ID:2024-Smith,John###"

Your Task: Write the code to clean this data and print a friendly welcome message.

1. Clean it: Remove the # symbols from both ends using strip().
2. Extract ID: The ID is the number between the colon : and the hyphen - (e.g., 2024). Use .find() and slicing to extract it.
3. Extract Name: The first name is everything after the comma , (e.g., John). Use .find() or .rfind() and slicing to extract it.
4. Final Output: Use an f-string to print the result in this exact format: "Welcome John! Your student ID is 2024."
