		maxwell86 on Jan 20, 2022 \| parent \| context \| favorite \| on: Why static languages suffer from complexity You suggested that Python type hints are useful. I laughed hard at that suggestion. Can you maybe just show how to type a Python function such that it does the absurdly simple thing of taking a numpy array of integers? `def fun(nump_array_of_ints: ???): ...` Just to show everyone just how "useful" type hints in Python _actually_ are.

  import numpy as np
  import numpy.typing as npt

  x = np.array([1, 2, 3])
  def foo(x: npt.NDArray[np.int_]) -> bool:
      return True
