Programming with Python on Termux: From Basics to Advanced

Introduction

Python is a highly popular programming language known for its flexibility and powerful libraries. Termux provides a Linux environment on Android devices, allowing the use of programming languages like Python. The integration of Termux and Python offers a robust environment for developing software, creating automation scripts, or building simple projects on mobile platforms. In this article, we’ll explore how to get started with Python programming, including the necessary setup and some simple projects to get you started.

Learning Objectives

By the end of this article, you will:

• Learn how to install and configure Python on Termux.
• Understand how to develop simple projects using Python on Termux.
• Explore the potential applications of Python and Termux integration.

Purpose of This Project

The aim of this project is to provide a practical guide to installing and using Python on Termux, enabling developers to write Python code directly on their Android devices. This project also demonstrates simple yet effective Python projects to help you get familiar with the Python-Termux integration for real-world applications, The Linux Experience on Mobile Devices.

Python Installation

Installing Python on Termux is straightforward. Here’s a step-by-step guide:

Once Python is installed, you can start working on some simple projects to hone your skills:

“Hello, World!” Program: Create a simple “Hello, World!” program, Learning Basic Data Types in Python.

print("Hello, World!")

Simple Calculator: Create a basic calculator using Python:

def add(a, b):
      return a + b

  def subtract(a, b):
      return a - b

  def multiply(a, b):
      return a * b

  def divide(a, b):
      if b != 0:
          return a / b
      else:
          return "Error: Division by zero"

  # Get user input
  a = float(input("Enter first number: "))
  b = float(input("Enter second number: "))
  operation = input("Enter operation (+, -, *, /): ")

  if operation == '+':
      print(f"Result: {add(a, b)}")
  elif operation == '-':
      print(f"Result: {subtract(a, b)}")
  elif operation == '*':
      print(f"Result: {multiply(a, b)}")
  elif operation == '/':
      print(f"Result: {divide(a, b)}")
  else:
      print("Invalid operation")

Simple Web Fetcher (Terminal-Based): Create a simple HTTP client to fetch data from a given URL:

import requests

  def fetch_url(url):
      try:
          response = requests.get(url)
          return response.text
      except requests.RequestException as e:
          return f"An error occurred: {e}"

  url = input("Enter URL to fetch: ")
  content = fetch_url(url)
  print("Content fetched from URL:")
  print(content)

import os

  def list_files(directory):
      try:
          files = os.listdir(directory)
          return files
      except FileNotFoundError as e:
          return f"Directory not found: {e}"

  directory = input("Enter directory path to list files: ")
  file_list = list_files(directory)
  print("Files in directory:")
  for file in file_list:
      print(file)

• Save this code to a file (e.g., list_files.py) and run it:

$ python list_files.py
