Python Input and Output
Python provides simple functions to take input from the user and output data to the screen.
-
📥 Input → Collect data from the user using the
input()function -
📤 Output → Display data using the
print()function
🖨️ Output in Python – print()
The print() function is used to show messages or variable values on the screen.
Syntax:
print(value1, value2, ..., sep=' ', end='\n')
✅ Examples:
print("Hello, World!")
print("Name:", "John")
print("Hello", end=" ")
print("World!")
-
sep: Separator between values (default is space) -
end: What to print at the end (default is newline\n)
🎤 Input in Python – input()
The input() function reads a line of text entered by the user.
Syntax:
variable = input("Enter something: ")
-
The input is always received as a string, even if the user types a number.
-
You can convert it to int/float using
int()orfloat().
✅ Examples:
name = input("Enter your name: ")
age = int(input("Enter your age: "))
🔄 Type Casting with Input
Since input() returns a string, you can cast it like this:
num1 = int(input("Enter number 1: "))
num2 = float(input("Enter number 2: "))
🧠 Summary Table
| Operation | Function | Returns |
|---|---|---|
| Display output | print() |

| Get input | input() |
