Milestone 1: Python Foundations & Data Science

🟦 Milestone 1: Python Foundations & Data Science

Master the core syntax, memory model, and high-performance libraries (NumPy, Pandas) that form the bedrock of AI and Data Engineering.

🚀 The Senior’s Starting Point

• Course PY-100: The Senior Mental Model: Shifting your mindset from “coding” to “engineering.”

📚 Slow-Paced Deep Dives (University Modules)

• Module 1: The Runtime & GIL (The Traffic Controller): PY-101. Understanding how Python actually runs code.
• Module 2: NumPy & Vectorization (The Calculator): PY-102. Speeding up math by avoiding loops.
• Module 3: Pandas & DataFrames (The Advanced Spreadsheet): PY-103. Cleaning and analyzing tables of data.
• Module 4: AsyncIO & Concurrency (The Busy Chef): PY-104. Multitasking while waiting for work.

🥅 Milestone Goals

1. Understand the GIL and its impact on performance.
2. Replace Python loops with Vectorized NumPy operations.
3. Perform complex data cleaning tasks in Pandas.
4. Handle thousands of I/O tasks using AsyncIO.
