# Chapter 2 — First Program, Printing, and the “Python Way” Instead of starting with 20 rules, we start with a tiny program you understand. Create `src/main.py` and write: ```python name = "Meetcode Student" print("Hello,", name) ``` Run it: ```bash python src/main.py ``` ## 2.1 Reading Errors Without Panic When Python shows an error, it usually tells you: - what happened (error type) - where it happened (file + line) - what line caused it The goal is not “avoid errors”. The goal is “read errors fast”. ### A small mistake example ```python print("Hello" ``` You will get a message about missing `)` and it points to the line. ## 2.2 Print Is Not Only for Beginners `print()` is a simple debugging tool. Even pros use it to quickly confirm: - “Did this function run?” - “What value is inside this variable?” - “Which branch did the program take?” Later you will learn logging, but print is a good start. ## 2.3 The “Small Debug Loop” (A Habit That Makes You Fast) When something breaks, do this loop: ```text 1) Reproduce the bug (same input, same steps) 2) Reduce the problem (smallest code that still fails) 3) Inspect values (print/log) 4) Fix one thing 5) Run again ``` ### A tiny example: checking your assumptions ```python items = ["10", "20", "30"] total = 0 for x in items: total = total + int(x) print(total) ``` --- ## Conclusion In this article, we explored the core concepts of All about Python - — First Program, Printing, and the “Python Way”.
