Before you begin
- Basic computer skills
The walkthrough
Step by step.
01
Step 1 of 5
Installing Python
Visit python.org and download the latest version. During installation, check "Add Python to PATH". Verify installation by opening terminal and typing: python --version
Field note
- Use Python 3.x (not Python 2)
- Install a code editor like VS Code or PyCharm
02
Step 2 of 5
Your First Print Statement
Create a new file called hello.py. The print() function displays output to the console.
python
# Your first Python program
print("Hello, World!")
print("Welcome to Python programming")
# Print multiple items
name = "Alice"
print("Hello,", name)Field note
- Python is case-sensitive
- Comments start with #
03
Step 3 of 5
Variables and Input
Variables store data. The input() function gets user input.
python
# Variables
name = "John"
age = 25
height = 5.9
# User input
user_name = input("What is your name? ")
print(f"Hello, {user_name}!")
# Type conversion
age_str = input("Enter your age: ")
age = int(age_str) # Convert string to integerField note
- Use descriptive variable names
- input() always returns a string

Step 4 of 5
Basic Math Operations
Python makes math easy with intuitive operators.
python
# Basic operations
addition = 10 + 5 # 15
subtraction = 10 - 5 # 5
multiplication = 10 * 5 # 50
division = 10 / 5 # 2.0
floor_division = 10 // 3 # 3
modulus = 10 % 3 # 1
exponent = 2 ** 3 # 8
# Calculator example
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
result = num1 + num2
print(f"Sum: {result}")Field note
- Use // for integer division
- Use ** for exponentiation (not ^)

Step 5 of 5
String Formatting
Python offers multiple ways to format strings.
python
name = "Alice"
age = 30
# f-strings (recommended)
message = f"My name is {name} and I am {age} years old"
# .format() method
message = "My name is {} and I am {} years old".format(name, age)
# String concatenation
message = "My name is " + name + " and I am " + str(age)
print(message)Field note
- f-strings are the most readable and efficient
- Convert numbers to strings with str()
