🐍 Python Input and Output

In Python (programming language), input and output allow your program to interact with the user. You can receive data from the user and display information on the screen.

🖊 Getting Input from the User

Python provides the input() function to take input from the user. The input is always returned as a string.

Example:

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

Sample Run:

Enter your name: Rahul
Hello, Rahul!

🔄 Input Type Conversion

Since input() returns a string, you often need to convert it to a number using type casting:

age = int(input("Enter your age: "))
print("Next year, you will be", age + 1)

🖨 Displaying Output

Python uses the print() function to display output on the screen.

Examples:

# Printing text
print("Hello, World!")# Printing variables
name = "Alice"
print("Name:", name)# Printing multiple values
age = 25
print(name, "is", age, "years old")

Output:

Hello, World!
Name: Alice
Alice is 25 years old

✨ Formatting Output

Python provides ways to format output nicely.

1️⃣ Using `+` for concatenation

name = "Alice"
age = 25
print("Name: " + name + ", Age: " + str(age))

2️⃣ Using Commas (Automatic space)

print("Name:", name, "Age:", age)

3️⃣ Using f-strings (Python 3.6+)

print(f"{name} is {age} years old")

🔢 Input Multiple Values

You can take multiple inputs using split():

x, y = input("Enter two numbers separated by space: ").split()
x = int(x)
y = int(y)
print("Sum:", x + y)
