Note that:

1. src/mycalulator is the package
2. main contains all the main files, and unless the mycalculator package is installed it can not import its code._

Steps to create your own package

1. Follow a similar directory structure.
2. Create a pyproject.toml file in the main directory, with all the necessary lines.
3. Run the below commands from the main directory.

To install this package locally,

Run : pip install .

If you want the package to automatically update its code,

Run: pip -e install .
