Hello
I’ve found this great package today, which allows you to set some constraints on your function parameters.
https://pypi.org/project/PyContracts/
Long story short, you can use the contracts like this:
@contract(a='int,>0', b='list[N],N>0', returns='list[N]')
def my_function(a, b):
...
or like this:
@contract
def my_function(a : 'int,>0', b : 'list[N],N>0') -> 'list[N]':
# Requires b to be a nonempty list, and the return
# value to have the same length.
...
I’m loving this!
