- Python 3.6 type checking
make sure python is 3.6 or above
python3 -m pip install -U mypy
Example code with typecheck
from typing import List
Vector = List[float]
def scale(scalar: float, vector: Vector) -> Vector:
return [scalar * num for num in vector]
# typechecks; a list of floats qualifies as a Vector.
new_vector = scale(2.0, [1.0, -4.2, 5.4])
print(new_vector)
then just run
mypy testtype.p <pre>
