The CRUD operation are done using the HTTP protocol:

• GET for reading lists of files (Read)
• GET for read one file if it is specified
• POST for creating a new file (Create)
• DEL for deleting the file (Delete)
• PUT for update the file (Update)

I test the API using curl and Postman

API are:

• http://localhost:5000/ [GET]
• http://localhost:5000/ [POST]
• http://localhost:5000/files [GET]
• http://localhost:5000/files/<file_name> [GET]
• http://localhost:5000/files/<file_name> [DELETE

Locally updated to Python3.8, fix virtual environment python 3.8
