🐍 PBSSD Python Programming Journey

Welcome to my learning repository! This project documents my progress in the Paschim Benga Society for Skill Development (PBSSD) Python Programming course.

💡 The Engineering Pivot: > Although my official curriculum shifted to Web Development on Day 16, I am continuing my Python mastery independently. This repository now documents my transition into self-taught advanced logic, bridging the gap between core Python and full-stack engineering.

🛠️ Current Tech Stack

• Language: Python 3.x
• Environment: Anaconda / Jupyter Notebooks / VS Code
• Focus: Logic Building, Data Structures, and Modular Programming

---

🗓️ Day 01 - Day 11: Foundations

Summary of core concepts covered in the initial weeks:

• Memory Management: Object IDs, Stack (LIFO), and PVM logic.
• Data Types: Dynamic typing, ASCII conversions (ord/chr), and Number Systems (Hex, Binary, Octal).
• Control Flow: if-elif-else ladders and basic while loops for automation.
• Math Assignments: 100+ problems solved across basic, intermediate, and advanced levels.

---

🗓️ Day 12: Armstrong Numbers & For-Loop Iterators

Focus: Digit logic and Range-based iteration.

1. Armstrong Number Logic

A number is an Armstrong number if the sum of its own digits each raised to the power of the number of digits equals the number itself. Example: $153$ ($3$ digits): $1^3 + 5^3 + 3^3 = 153$.

2. The for Loop & range()

• Stream Processing: Python treats sequences as data streams starting at index 0.
• range(start, stop, step): Mastered forward and reverse iteration.

---

🗓️ Day 13: Nested Loops & Pattern Geometry

Focus: Coordinate-based iteration and the "Clock Hand" model.

• Clock Hand Model: Outer loop (Hour) and Inner loop (Minute).
• Pattern Logic:
  • Left Triangle: if i >= j
  • Right Triangle: if i + j >= r + 1
  • Diagonal (X-Shape): if i == j or i + j == r + 1

---

🗓️ Day 14: Matrix Operations & Coordinate Mapping

Focus: Numerical matrices and 2D searching.

• Numerical Filling: Implemented row-major and column-major matrix population.
• 2D Search: Built a search algorithm that returns the exact Coordinate Pair $(x, y)$ of a target value.

---

🗓️ Day 15: Geometric Logic & Advanced Pattern Design

Focus: Multi-conditional logic and region filling.

• Advanced Shapes: Implemented "N" and "Z" shapes using diagonal boundary conditions.
• Symmetry: Mastered the center point calculation (f + 1) // 2 for odd-numbered grids.
• Region Filling: Used inequalities to create solid geometric shapes within matrices.

---

🗓️ Day 16: Functions & Functional Programming

Focus: Reusability and Lambda Expressions.

• Types: Built-in vs. User-defined (def).
• Lambda Functions: Single-line, anonymous functions for quick operations.
• Higher-Order Functions: Passing functions as arguments to other functions to create modular "tools."

---

🗓️ Day 17: Advanced Iterators & Arguments

Focus: Scalable functions and Jupyter integration.

• Tools: map() for transformations and filter() for conditional data extraction.
• Scalability: * *args: Tuple-based positional arguments.
  • **kwargs: Dictionary-based keyword arguments.
• Environment: Successfully migrated to Jupyter Notebooks for interactive debugging.
