Problem with Exercise 1, Problem 2:

After defining 'create_line_geom(points)' (At "2: Create a function called create_line_geom()..."), the first assert, ..."Input should be a list", is triggered. I get the error, "TypeError: 'list' object is not callable". I wasn't sure if I should validate the assert list with '[]' (l = [] / type(points) == l, "Input should be a list") within the defined function, or I assigned the two Points in line1 in error:

def create_line_geom(points):
    l = []
    type(points) == l, "Input should be a list"
    assert len(points) >= 2, "LineString object requires at least two Points"
    assert print(points) == 'shapely.geometry.point.Point', "All List values should be Shapely Point objects!"
    return LineString(points)

line1 = Point(45.2, 22.34), Point(100.22, -3.20)

create_line_geom(line1)
