Installing Python

To begin coding, you first need to install Python on your computer.

Step 1: Download Python

Visit the official Python website:

Python Official Website

Download the latest version for your operating system.

Step 2: Install Python

During installation, make sure you check the option:

Add Python to PATH

This allows Python to run from the command line.

Step 3: Verify Installation

Open your terminal or command prompt and type:

python --version

You should see something like:

Python 3.13.0

---

Writing Your First Python Program

Open any code editor like:

• Visual Studio Code
• PyCharm
• Sublime Text

Create a file named:

hello.py

Add this code:

print("Welcome to Python Programming!")

Run the file using:

python hello.py

Output:

Welcome to Python Programming!

Congratulations! You have written your first Python program.

---

Understanding Variables in Python

Variables store information in memory.

Example:

name = "John"
age = 25
height = 5.9

Here:

• name stores text
• age stores an integer
• height stores a decimal number

You can print variables like this:

print(name)
print(age)

Output:

John
25

---

Python Data Types

Python supports different data types.

Data Type	Example
Integer	10
Float	3.14
String	"Python"
Boolean	True

Example:

number = 100
price = 99.99
language = "Python"
is_coding_fun = True

---

Taking User Input

Python allows users to enter data.

Example:

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

Output:

Enter your name: Alex
Hello Alex

---

Conditional Statements

Conditions help programs make decisions.

Example:

age = 18

if age >= 18:
    print("You are eligible to vote.")
else:
    print("You are underage.")

Output:

You are eligible to vote.

---

Python Loops

Loops repeat code multiple times.

For Loop

for i in range(5):
    print(i)

Output:

0
1
2
3
4

While Loop

count = 1

while count <= 5:
    print(count)
    count += 1

---

Functions in Python

Functions help organize reusable code.

Example:

def greet():
    print("Welcome to Python!")

greet()

Functions can also accept parameters.

def greet(name):
    print("Hello", name)

greet("Sarah")

Output:

Hello Sarah

---

Lists in Python

Lists store multiple values.

Example:

fruits = ["Apple", "Banana", "Orange"]

print(fruits[0])

Output:

Apple

You can loop through lists:

for fruit in fruits:
    print(fruit)

---

Dictionaries in Python

Dictionaries store data in key-value pairs.

Example:

student = {
    "name": "John",
    "age": 20,
    "course": "Python"
}

print(student["name"])

Output:

John

---

File Handling in Python

Python can read and write files.

Writing to a File

file = open("notes.txt", "w")
file.write("Python is awesome!")
file.close()

Reading a File

file = open("notes.txt", "r")
print(file.read())
file.close()

---

Error Handling

Errors can crash programs. Python uses try and except to handle them.

Example:

try:
    number = int(input("Enter a number: "))
    print(number)
except:
    print("Invalid input")

---

Object-Oriented Programming Basics

Python supports object-oriented programming (OOP).

Example:

class Student:
    def __init__(self, name):
        self.name = name

    def display(self):
        print("Student Name:", self.name)

s1 = Student("Emma")
s1.display()

Output:

Student Name: Emma

---

Popular Python Libraries

Python has thousands of powerful libraries.

Library	Purpose
NumPy	Numerical computing
Pandas	Data analysis
Matplotlib	Data visualization
TensorFlow	Machine learning
Flask	Web development

Some famous frameworks include:

• Django
• Flask
• TensorFlow

Mini Project: Simple Calculator

Let’s build a beginner-friendly calculator.

num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))

operation = input("Choose (+, -, *, /): ")

if operation == "+":
    print(num1 + num2)

elif operation == "-":
    print(num1 - num2)

elif operation == "*":
    print(num1 * num2)

elif operation == "/":
    print(num1 / num2)

else:
    print("Invalid operation")

This project teaches:

• User input
• Conditions
• Mathematical operations
