Explaining the Makefile included

This Makefile defines a set of commands to automate tasks related to installing dependencies, running tests, formatting code, and performing linting. Makefiles are used in Unix-based systems to define rules and dependencies for building projects or executing tasks.

Here's a breakdown of the Makefile targets:

1. install:

   • This target is used to install the required dependencies for the project.
   • It runs the following commands:
     • pip install --upgrade pip: This command upgrades the pip package manager to the latest version.
     • pip install -r requirements.txt: This command installs the Python dependencies listed in the requirements.txt file.

2. test:

   • This target is used to run tests on Jupyter notebooks using the pytest-nbval plugin, which allows testing Jupyter notebooks.
   • It runs the following commands:
     • python -m pytest --nbval ./pandas/ObesityExploration.ipynb: This command runs tests on the ObesityExploration.ipynb Jupyter notebook using pytest.
     • python -m pytest --nbval ./pandas/learning_pandas.ipynb: This command runs tests on the learning_pandas.ipynb Jupyter notebook using pytest.
     • python -m pytest --nbval ./pandas/portfolio-projects/prob_1_analyze_sales_data.ipynb: This command runs tests on the prob_1_analyze_sales_data.ipynb Jupyter notebook located in the portfolio-projects directory using pytest.

3. format:

   • This target is used to format the Python code using the black code formatter.
   • It runs the black *.py command, which formats all Python files in the current directory.

4. lint:

   • This target is used to perform code linting using pylint.
   • It runs the pylint command without specifying a file or directory, which typically means it will check all Python files in the current directory.

5. all:

   • This is a special target that specifies a group of tasks that should be executed together when running make all or simply make.
   • The all target includes the install, lint, and test targets. Therefore, running make all will execute all these tasks in sequence.

Each target in the Makefile specifies the commands to be executed when that target is called. You can run a specific target by using the make command followed by the target name, for example:

make install
make test
make format
make lint
make all

Makefiles are helpful for automating repetitive tasks in your project workflow, and they are commonly used in software development to streamline build processes, testing, and other routine tasks.
