The input() function
The input() function in Python is used to take user input from the console. It allows you to interact with the user by prompting them to enter data, which can then be processed in your program.
Basic usage
The input() function pauses program execution and waits for the user to type something in the console. Once the user presses Enter, the function returns the input as a string.
Basic usage
The input() function pauses program execution and waits for the user to type something in the console. Once the user presses Enter, the function returns the input as a string.
user_input = input("Enter a value: ")- The string passed as an argument to input() is the prompt that appears to the user.
- The returned value is always of type string, regardless of what the user enters.
Example:
name = input("What is your name? ")
print(f"Hello, {name}!")Output:
What is your name? Alice Hello, Alice!
In this example:
- The program prompts the user for their name.
- After entering their name, it greets them using the input.
This function is fundamental in creating interactive programs that respond to user input, making your applications more dynamic and engaging.
