Python Programming
1. Introduction & Use Cases
Python is a high-level, interpreted programming language known for its readability and versatility. In the context of Termux, Python is the go-to language for automation, security auditing, and data analysis.
- Cybersecurity: Writing exploit scripts, network scanners, and OSINT tools.
- Automation: Scripting repetitive tasks within the Android environment.
- Web Development: Running lightweight servers like Flask or Django.
- Data Science: Performing complex calculations and data visualization.
2. Basic Syntax & Variables
Python uses clean, indentation-based syntax. To install Python in Termux, use pkg install python.
bash — variables.py
# Basic variable assignment
name = "Termux Hub"
version = 3.11
is_mobile = True
print(f"Welcome to {name}")
print(f"Current Version: {version}")3. Control Flow & Functions
Managing logic and reusable code blocks in Python.
bash — logic.py
def check_access(level):
if level >= 10:
return "Root Access Granted"
else:
return "User Access Restricted"
for i in range(3):
print(f"Attempt {i+1}: {check_access(i*5)}")4. Core Commands Cheat-sheet
python script.py- Execute a Python script.pip install [package]- Install third-party libraries.python -m http.server 8080- Start a quick web server.len(obj)- Get the length of a list or string.type(obj)- Check the data type of an object.
5. Popular Libraries & Frameworks
- Requests: The standard for making HTTP requests.
- Scrapy/BeautifulSoup: For web scraping and parsing HTML.
- Pandas/NumPy: For data manipulation and math.
- Flask/FastAPI: Modern web frameworks.
- Scapy: Powerful packet manipulation for security testing.
6. Advanced Practical Example: Web Scraper
A simple script to fetch the title of a website using the requests and BeautifulSoup libraries.
bash — scraper.py
import requests
from bs4 import BeautifulSoup
def get_title(url):
try:
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
return soup.title.string
except Exception as e:
return str(e)
print(get_title("https://example.com"))
