Build a type checker to check method inputs

- composite types ([str], [int], etc...)
- dicts types ({'name': str, 'age': float, etc...})
To build a more complex type-def u can use the available Options in typechk module
- Or(type-def, type-def, ...)
- Missing() (Only make sense in dict types)
- IsNone() (accept None value)
Example of type definition
A dict object, with the following attributes
- `name` of type string
- optional `age` which can be int, or float
- A list of children each has
- string name
- float age
c = Checker({

Dataset Card for "pypi_clean"
All of the latest package versions from pypi. The original data came from here. I pulled the latest versions of each package, then extracted only md, rst, ipynb, and py files.
I then applied some cleaning:
- rendering notebooks
- removing leading comments/licenses
- Downloads last month
- 233
