What are input and output functions in Python?
In Python, input() and print() are two fundamental built-in functions used for interacting with the user and displaying information, respectively.
input():
The input() function is a built-in function that reads input from the user and returns it as a string. It's often used to get user input, such as names, ages, or preferences. When called, it displays a prompt to the user, usually in the form of ">", and waits for the user to enter some text.
Here are some key points about the input() function:
Default behavior: The default behavior is to display the prompt and wait for user input. Return type: It returns the input as a string, which can be used in various ways in your program. Raw input: By default, Python's input() function strips newline characters from the end of the input (i.e., removes any trailing newlines). To get raw input without this stripping, use the built-ininput() function with the end='' argument: input("Enter something: ", end='').
print():
The print() function is a built-in function that outputs text to the console. It's commonly used for displaying messages, results, or data. When called, it displays its arguments on the console.
Here are some key points about the print() function:
Default behavior: The default behavior is to display the output as a string. Argument types: You can pass multiple arguments to print(), which will be displayed separated by spaces. You can also use thesep and end arguments to customize the formatting. No newline: By default, print() does not add a newline character at the end of its output. If you want to include a newline, specify it explicitly: print("Hello, world!", end='n').
Example usage:
Here's an example of using input() and print():
name = input("What is your name? ")
print(f"Hello, {name}! Nice to meet you.")
This code prompts the user for their name, stores it in a variable name, and then prints out a personalized greeting message.
Common use cases:
User interaction: Use input() to get user input and store it in variables. Data output: Use print() to display messages, results, or data to the console. Debugging: Use print() with debugging information (e.g., variable values) to troubleshoot issues.In summary, input() is used for getting user input and storing it as a string, while print() is used for displaying text output to the console. Both functions are essential for building interactive Python programs that engage with users and display results.
