🧾 Technical Definition
🖥️ What is Programming in Engineering Context?
Programming is the process of designing and implementing algorithms using a formal language that a computer can execute.
Formal Definition:
Programming is the systematic translation of computational logic into executable instructions using programming languages.
In engineering terms:
Programming = Mathematical modeling + Logical structuring + Automation
⚙️ Python Programming Structure
A typical Python program consists of:
