I think this looks good. There is scope to reduce some of the Any to something more specific

[jenshnielsen]

It looks like @Dominik-Vogel is right

def my_test_func(a: float):
    return a + 1


if __name__ == "__main__":
    my_test_func(1)
    my_test_func(1.0)
    my_test_func(1.0 + 1.0j)

Type checks correctly for int and float but not for complex

[jenshnielsen]

And for a bit more fun

import numpy as np

def my_test_func(a: float):
    return a + 1


if __name__ == "__main__":
    my_test_func(1)
    my_test_func(1.0)
    my_test_func(1.0 + 1.0j)
    my_test_func(np.int32(1))
    my_test_func(np.float64(1))

with https://github.com/numpy/numpy-stubs installed as of master today.

This looks good. Only remaining point is to change all new Union[float,int] to float
