Python Input and Output: A Beginner’s Guide

Python provides built-in functions for taking input from the user and displaying output on the console. Here are the main functions for input and output:

Input Functions

  • input(): This function takes input from the user through the keyboard and returns it as a string. It can also take an argument, which is displayed as a prompt before the user enters the data.

Here is an example:

name = input("Enter your name: ")
print("Welcome, " + name + "!")

Output Functions

  • print(): This function is used to display output on the console. It can take one or more arguments separated by commas.

Here is an example:

print("Hello, World!")
String Formatting

String formatting is used to format the output in a specific way. Here are three ways to format strings in Python:

  • Using the % operator: This operator is used to format strings by replacing placeholders with values.

Here is an example:

name = "John"
age = 25
print("My name is %s and I am %d years old." % (name, age))
  • Using the str.format() method: This method is used to format strings by replacing placeholders with values.

Here is an example:

name = "John"
age = 25
print("My name is {} and I am {} years old.".format(name, age))
  • Using f-strings: This is a new way of formatting strings introduced in Python 3.6. It is similar to using placeholders, but with a simpler syntax.

Here is an example:

name = "John"
age = 25
print(f"My name is {name} and I am {age} years old.")
