This is an oppurtunity for me to learn how to create a function, store in TestPyPI enviroment, and use it in a notebook.
! pip install -i https://test.pypi.org/simple/ lambdata6==1.1
from my_lambdata6.my_mod import enlarge
print(enlarge(8))
website containing the function: https://test.pypi.org/project/lambdata6/1.1/
