git clone git@github.com:alimulondo/python-code-katas.git katas
cd katas

pip install -r requirements.txt

Before you start coding, create and switch to a branch called dev:

git checkout -b dev

Please complete the exercises in the following order:

1. FizzBuzz (src/katas/fizz_buzz.py)
2. Prime Factors (src/katas/prime_factors.py)
3. Read/Write JSON (src/katas/read_write_json.py)
4. Roman Numerals (src/katas/roman_numerals.py)
5. String Calculator (src/katas/string_calculator.py)
6. Unique String Finder (src/katas/unique_string_finder.py)
7. Env Secret Generator (src/katas/env_secret_generator.py)
8. Array Diff (src/katas/array_diff.py)

Open each file and follow the beginner-friendly instructions inside. Write your solution in the space provided.

Each kata has its own test file in the tests/ directory. You can run all tests or a single test file.

python -m unittest discover tests -p '*_test.py'

For example, to run only the FizzBuzz tests:

python -m unittest tests/fizz_buzz_test.py

Replace fizz_buzz_test.py with the test file you want to run.

After you finish all exercises, you can commit your changes and push your dev branch to your fork or repository.

git add .
git commit -m "Complete code katas"
git push origin dev

Happy coding! If you get stuck, read the instructions in each file carefully and try running the tests for hints.
