User Input

In any program, getting user input is essential, whether it's for a simple calculator or an advanced application. In Python, you can get user input using the built-in input() function. Here's how you can use it effectively:

Basic Example

name = input("Enter your name: ")
print(f"Hello, {name}!")

• input("Enter your name: "): Displays a prompt to the user and waits for their input.
• Once the user enters value, The entered value is returned as a string.

Converting Input to Other Data Types

The input() function always returns a string. If you need a different type (e.g., integer or float), you can convert it using type casting.

Convert to Integer

age = int(input("Enter your age: "))
print(f"You are {age} years old.")

Convert to Float

price = float(input("Enter the price: "))
print(f"The price is ${price:.2f}.")

Convert to Boolean

confirm = input("Do you agree? (yes/no): ").lower() == 'yes'
print(f"Your response: {confirm}")

Handling Multiple Inputs

Space-separated Input

numbers = input("Enter numbers separated by space: ").split()
print(f"You entered: {numbers}")

Comma-separated Input

values = input("Enter comma-separated values: ").split(',')
print(f"You entered: {values}")
