# Chapter 9 — Modules, Packages, and Import (Organize Your Code) This chapter uses “house rooms” as a metaphor. ## 9.1 One File = One Room If `math_tools.py` has functions, you import them: ```python from math_tools import add print(add(1, 2)) ``` ## 9.2 Packages (A Folder That Acts Like a Module) ```text src/ meetcode_tools/ __init__.py text.py numbers.py ``` Import: ```python from meetcode_tools.text import clean ``` ## 9.3 The Most Common “Import Error” Cause You ran Python from the wrong folder. Fix: run from the project root, or adjust your `PYTHONPATH`, or install your package in editable mode. --- ## Conclusion In this article, we explored the core concepts of All about Python - — Modules, Packages, and Import (Organize Your Code).
