Examples of User Input and Output in Python

📚 Quick Study Guide

• ⌨️ User Input: Python uses the input() function to get input from the user. The input is always read as a string.
• 📤 Output: Python uses the print() function to display output to the console. You can print strings, numbers, and other data types.
• 🔄 Type Conversion: Since input() returns a string, you might need to convert the input to other data types (like integers or floats) using int() or float().
• ➕ Concatenation: You can combine strings using the + operator or using f-strings for more readable output.
• 💡 Formatted Output: Use f-strings (e.g., f"The result is: {result}") for easy and readable variable insertion into strings.
• 🐞 Error Handling: Be aware of potential errors like ValueError when converting input to a different type. Use try-except blocks to handle these gracefully.
