Input and Output in Python

Python provides simple ways to take input from users and display output.

1. Output Using `print()`

The print() function displays text, variables, or expressions.

# Simple output
print("Hello, Python!")

# Printing multiple values
name = "Alice"
age = 25
print("Name:", name, "Age:", age)

# Using formatted strings (f-strings)
print(f"My name is {name} and I am {age} years old.")

# Using separator and end
print("Python", "is", "fun", sep="-", end="!\n")  # Output: Python-is-fun!

2. Input Using `input()`

The input() function reads user input as a string.

# Take user input
name = input("Enter your name: ")
age = input("Enter your age: ")

print(f"Hello {name}, you are {age} years old.")

3. Type Conversion for Input

input() always returns a string, so convert to required data type:

# Convert input to integer
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))

sum = num1 + num2
print(f"Sum: {sum}")

# Convert to float
height = float(input("Enter your height in meters: "))

4. Reading Multiple Inputs

Using split() to read multiple values:

# Enter multiple numbers separated by space
numbers = input("Enter numbers: ").split()
# Convert each to integer
numbers = [int(num) for num in numbers]
print(numbers)

5. Key Points

print() is used for output, supports multiple arguments, formatting, and separators.
input() is used for user input, always returns a string.
Use type conversion (int(), float()) to handle numeric inputs.
split() and list comprehension help read multiple inputs efficiently.
