About This Collection
This is a curated set of 64 practical Python code snippets designed for learning and quick reference. Each snippet demonstrates a specific programming concept, algorithm, or common task you’ll encounter in real-world Python development. Documentation was generated with mshell v.1.4.1 (shell for AI and Mathematics) and md file with code was checked to run by mshell v.1.4.1
What you’ll find here:

String manipulation and text processing techniques
Numeric operations, type conversions, and mathematical functions
List operations, comprehensions, and functional programming patterns
Control flow structures (loops, conditionals, pattern matching)
Functions, lambdas, decorators, and closures
Object-oriented programming basics (classes, inheritance, instance vs class members)
Pattern generation and algorithmic challenges
Python-specific features (iterators, generators, *args, **kwargs)

Who is this for:

Beginners learning Python fundamentals
Developers transitioning from other languages
Anyone preparing for coding interviews
Programmers looking for quick syntax references

All code blocks have been verified to run without errors in Python 3.12+. Simply copy, paste, and execute to see immediate results.

About This Collection
This is a comprehensive set of 64 ready-to-run Bash script snippets designed to help you master shell scripting in Ubuntu/Debian environments. Each snippet is a complete, working example that demonstrates a specific scripting technique or solves a common task. Documentation was generated with mshell v.1.4.1 (shell for AI and Mathematics) and md file with code was checked to run by mshell v.1.4.1

What you’ll find here:

Variable declaration, manipulation, and scope management
String operations (length, concatenation, case conversion, substring extraction)
Arithmetic operations and numeric comparisons
Control structures (if/else, for loops, while loops, case statements)
Arrays and iteration techniques
File and directory operations (creation, deletion, copying, searching)
Text processing (grep, sed, line counting, pattern matching)
Functions with parameters and return values
Command-line argument handling
Date/time operations and system information retrieval

Who is this for:

Linux beginners learning Bash scripting
System administrators automating routine tasks
Developers writing deployment or build scripts
Anyone preparing for DevOps/SRE interviews

Environment: All scripts are tested and verified to run on Ubuntu 24.04 as a regular user (no root required). They use /tmp for temporary files with $$ (process ID) for uniqueness and clean up after themselves.
How to use: Each snippet is a complete, self-contained script. Copy the code block, save it to a .sh file, make it executable with chmod +x script.sh, and run it with ./script.sh. Experiment by changing values and parameters to deepen your understanding.

This is a short description of the main features for Every Day Programmer’s Notebook – a natural client extension for the mshell Ecosystem (mshell v1.4.1 – shell for AI & Mathematics). Other parts of the ecosystem include mshell itself, as the core of the entire ecosystem, mshell Studio (mshell Library Manager + mshell Knowledge Database and Validator), and mshell Editor (edi): https://www.appservgrid.com/paw92/index.php/2026/01/05/mshell-ecosystem-short-description-of-main-components/

If you are a programmer and use a Linux, macOS, or Raspberry Pi machine as your daily workstation, or even as an occasional tool — this application is exactly what you need.
It’s not a single utility but a unified ecosystem of tools designed to simplify your everyday routine.

Instead of juggling dozens of separate apps, Everyday Programmer’s Notebook gives you one clean environment containing everything you constantly need.

What’s inside this unified suite?

• Scientific & Programmer Calculator
  Two complete modes in one tool.
  Scientific mode supports decimal arithmetic, logarithms, roots, powers, trigonometric functions (in degrees or radians), inverse operations and more.
  Programmer mode works simultaneously in binary, octal, decimal and hexadecimal, performs logical operations (AND, OR, XOR, NOT, shifts) and standard arithmetic within all four numeral systems.
• Unit Converter
  Instant conversion between metric and imperial systems: length, area, volume, temperature and more.
  Simple, accurate and always at hand.
• Local Digital Clock
  A clean, elegant digital time display synchronized with your system clock.
• World Clock
  Nine major world cities with automatic time-zone offsets, updated every second.
• Timer & Stopwatch
  Precise timing tools with start/stop/reset controls — perfect for productivity tracking or long-running tasks.
• Calendar (25-year range)
  A lightweight calendar viewer covering decades — ideal for scheduling, planning, or viewing past and future dates.
• Password Generator (up to 64 characters)
  Fully customizable:
  Uppercase / lowercase letters, digits, symbols — enable or disable any group.
  Creates strong passwords instantly.
• Color Picker (two modes)
  Digital palette (RGB/HEX/HSL) and analog spectrum mode.
  Perfect for UI work, design, theming or coding.
• Advanced Notebook / Text Reader & Editor
  A powerful page-based notebook that supports text, images and tables on each page.
  Key features include:
  — Auto-scrolling (digital reading mode)
  — Line numbering
  — Grid overlays
  — Page-specific background colors
  — Per-page text color and font size
  — Theme switching for the whole application
  — Unlimited number of pages (limited only by your hardware)
  — Import from TXT, MD, RTF, DOC, DOCX, PDF
  — Export to TXT, HTML, Markdown, DOCX, PDF
  — Image insertion
  — Searching and Replacement options
  — Table creation with text and/or images inside cells
  — Saving & loading notebook files with virtually unlimited pages, limited only by the user’s hardware

This is not a simple notebook — it is a unified environment for writing, reading, organizing, and presenting your information. Contact info about Everyday programmer’s notebook (all versions: MacOS, Linux, Raspberry PI) Igor Lukyanov, Art2Dec SoftLab, igor_lukyanov@appservgrid.com
