⚡ Prerequisites

  • Basic Python syntax knowledge
  • Understanding of print statements
  • Familiarity with strings

1. Getting Input from Users

The Input Function

The input() function allows your program to receive data from users:

name = input("What is your name? ") print("Hi there, " + name)

Sample execution:

What is your name? John Doe Hi there, John Doe

Key Points

  • The text inside parentheses is the prompt
  • Users press Enter to submit input
  • Input can be stored in variables

Create a program that asks for the user's name and greets them:

What is your name? Alice Hello Alice! Welcome to Python programming!
# Write your code here

2. Working with Variables

Storing User Input

Variables store values for later use:

name = input("What is your name? ") print("Hi, " + name + "!") print("Keep up the work, " + name + "!")

Variable Naming

  • Use descriptive names
  • Start with letter or underscore
  • Use lowercase with underscores
