neuralib.util.func.create_fn(name, sign, body='pass', *, globals=None, locals=None)[source]

Example:

>>> add = create_fn('add', (['a', 'b'], int), 'return a + b')
>>> add(1, 2)
3
>>> def add_sign(a: int, b:int) -> int:
...     pass
>>> add = create_fn('add', add_sign, 'return a + b')
>>> add(1, 2)
3

Signature Example

>>> def f(a, b:int, c=0, d:int=1) -> int:
(['a', ('b', int), ('c', None, '0'), ('d', int, '1')], int)
