How to Get Started with Python

1. Install Python

Visit the official Python website to download and install Python. Once installed, verify by running:

bash
python --version

2. Choose an Editor

Popular Python editors include:

• VS Code (lightweight and powerful)
• PyCharm (great for larger projects)
• Jupyter Notebook (ideal for data science)

Your First Python Program

Let’s write a simple program that greets the user:

python
# A simple greeting program
name = input("What's your name? ")
print(f"Hello, {name}! Welcome to the world of Python.")

Save it as greet.py and run using:

bash
python greet.py

Exploring Python’s Features

1. Working with Data

Python makes handling data a breeze:

python
# Basic list operations
fruits = ['apple', 'banana', 'cherry']
fruits.append('orange')
print(fruits)

2. Automate Tasks

Automate repetitive tasks like renaming files:

python
import os

# Rename files in a folder
folder = 'my_folder'
for count, filename in enumerate(os.listdir(folder)):
    new_name = f"file_{count}.txt"
    os.rename(os.path.join(folder, filename), os.path.join(folder, new_name))

3. Build Web Applications

Frameworks like Flask and Django let you build robust web apps:

python
from flask import Flask

app = Flask(__name__)

@app.route('/')
def home():
    return "Hello, World!"

if __name__ == '__main__':
    app.run(debug=True)

Advanced Topics

Once comfortable with the basics, explore:

• Data Science: Use Pandas and Matplotlib for data analysis.
• Machine Learning: Dive into AI with scikit-learn or TensorFlow.
• Cybersecurity: Automate penetration testing with tools like Scapy.
