This is an exercise that I did for a python advanced learning course.

The exercise is divided into two parts:

• A python REST app, that has several POST endpoints that only accepts a JSON input. Otherwise, returns HTTP 500 error. The endpoints are:

  • /suma/ , adds element-wise the JSON float lists and returns the result as HTTP response.
  • /resta/ , subtracts element-wise the JSON float lists and returns the result as HTTP response.
  • /mult/ , multiplies element-wise the JSON float lists and returns the result as HTTP response.
  • /divis/ , divides element-wise the JSON float lists and returns the result as HTTP response.

• A python module, that has a class with all the operation functions to make the endpoints work.

JSON input should be in the form:

{'v1': type.List[float], 'v2': type.List[float]}.

The python module is named calclib. It contains a float vector calculator with safe input check. Also, has unittest tests and Sphinx documentation source files.

Ensure that an up-to-date version of setuptools is installed:

$ python3 -m pip install --upgrade setuptools

To install the module:

$ cd calclib_packaging
$ python3 setup.py sdist
$ pip3 install dist/calclib-1.0.tar.gz

To run app.py, flask is needed:

$ pip3 install -U flask

Then:

$ python3 -m flask run

$ cd calclib_packaging
$ python3 setup.py test

Need Sphinx and furo :

$ pip3 install sphinx furo

To generate documentation:

$ cd calclib_packaging/docs
$ make html
