🐍 Python Input and Output Functions

Python provides built-in functions to take input from the user and display output on the screen.

🔹 Input Function: input()

The input() function is used to get user input as a string.

🧠 Syntax:

python

Copy

Edit

variable = input("Enter something: ")

✅ Example:

python

Copy

Edit

name = input("What is your name? ")

print("Hello, " + name + "!")

📝 Note: The input is always stored as a string, even if you enter numbers. To convert it, use functions like int() or float():

python

Copy

Edit

age = int(input("Enter your age: "))

🔹 Output Function: print()

The print() function is used to display output on the screen.

🧠 Syntax:

python

Copy

Edit

print(object1, object2, ..., sep=' ', end='\n')

✅ Examples:

python

Copy

Edit

print("Hello, world!")

You can print multiple items:

python

Copy

Edit

print("Name:", "Alice")

Use sep to change the separator between items:

python

Copy

Edit

print("2025", "04", "12", sep="-")

# Output: 2025-04-12

Use end to change what’s printed at the end:

python

Copy

Edit

print("Hello", end=" ")

print("World")

# Output: Hello World

🧪 Example Program:

python

Copy

Edit

name = input("Enter your name: ")

age = int(input("Enter your age: "))

print("Hi", name + "!", "You are", age, "years old.")

Let me know if you'd like examples for file input/output (open(), read(), write()) too!
