Multiple Choice Questions on Python User Interaction

📚 Quick Study Guide

• 🔑 The `input()` function is used to get user input in Python. It always returns a string.
• 🔄 To get numerical input, you need to convert the string to an integer or float using `int()` or `float()`.
• ⚠️ Always handle potential errors, such as `ValueError` if the user enters non-numeric input when expecting a number.
• 💡 Use `try-except` blocks for error handling.
• 💬 Provide clear prompts within the `input()` function to guide the user.
• 🧮 String formatting (f-strings or `.format()`) can be used to create dynamic prompts or output messages.
• 🛡️ Validate user input to ensure it meets the expected criteria before processing it.
