CEPEDI Python Course: beginner Python exercises, Git and PostgreSQL notes

curso-python-cepedi is a collection of small, standalone Python 3 exercise scripts written during the CEPEDI Python course, plus Portuguese study notes on Git and on running PostgreSQL with pgAdmin on Windows, for beginners learning programming fundamentals.

Each script in python_geral/ is one independent exercise with a docstring header that explains what it does and which concepts it practices. The code comments and the program output are in Portuguese.

Python exercises for beginners · Python basics · input and output · if/else · for and while loops · lists · dictionaries · functions · try/except · Git cheat sheet · PostgreSQL on Windows · pgAdmin

What's inside

• Standalone exercises (.py scripts) covering the basics: input and output, arithmetic, conditionals, loops, lists, dictionaries, functions and exception handling.
• Small utilities and drafts used during the classes.
• Study notes (Portuguese): a Git quick guide and a PostgreSQL-on-Windows guide.

Getting started

Prerequisites: Python 3.8+ (3.10 or 3.11 recommended). Git is optional, for cloning.

1. Clone the repository:

git clone https://github.com/WednyFernandes/curso-python-cepedi.git
cd curso-python-cepedi

2. Run any exercise (Windows / PowerShell):

python .\python_geral\atv03-medianota.py

No dependencies to install. Every script uses only the Python standard library.

FAQ

Is this a full Python course? No. It's the exercise folder from the CEPEDI course: short scripts, one concept each, meant for teaching and practice.

Why is the code in Portuguese? The course was taught in Portuguese, so variable names, comments, prompts and the study notes are in Portuguese.

Do the scripts depend on each other? No. Each file in python_geral/ is independent. Read its docstring header for what it does, then run it directly.
