1.3.2 Getting User Input with input()

The input() function is used to receive input from the user during program execution.
It pauses the program and waits for the user to type a value.

How input() Works

When input() is called:

• The program displays an optional prompt
• The user enters text
• The input is returned as a string

This behavior is consistent regardless of what the user types.

---

Input and Data Types

Because input() always returns a string:

• Numeric input must be converted before calculations
• Type conversion is often required

Understanding this behavior is critical for avoiding logic errors.

Common Use Cases

• Asking for user information
• Reading configuration values
• Interactive scripts and tools

📌 Note:
Always consider type conversion when working with user input.
