Resources

Read or watch:

• Python 3 typing documentation
• MyPy cheat sheet

Learning Objectives

General

At the end of this project, you are expected to be able to explain to anyone, without the help of Google:

• Type annotations in Python 3
• How you can use type annotations to specify function signatures and variable types
• Duck typing
• How to validate your code with mypy

Requirements

General

• Allowed editors: vi, vim, emacs
• All your files will be interpreted/compiled on Ubuntu 18.04 LTS using python3 (version 3.7)
• All your files should end with a new line
• The first line of all your files should be exactly #!/usr/bin/env python3
• A README.md file, at the root of the folder of the project, is mandatory
• Your code should use the pycodestyle style (version 2.5.)
• All your files must be executable
• The length of your files will be tested using wc
• All your modules should have a documentation (python3 -c 'print(import("my_module").doc)')
• All your classes should have a documentation (python3 -c 'print(import("my_module").MyClass.doc)') your functions (inside and outside a class) should have a documentation (python3 -c 'print(import("my_module").my_function.doc)' and python3 -c 'print(import("my_module").MyClass.my_function.doc)')
• A documentation is not a simple word, it’s a real sentence explaining what’s the purpose of the module, class or method (the length of it will be verified)
