Python Tip

Keyword-only parameters in Python 3.x

Use * in function parameter lists to force the use of keyword arguments for certain parameters:

Code

class Coordinate:
    def __init__(self, *, latitude=0, longitude=0):
        self.latitude=latitude
        self.longitude=longitude
...


Coordinate(34, 37)
TypeError: __init__() takes 1 positional argument but 3 were given


Coordinate(latitude=34, longitude=37)
Coordinate(longitude=37, latitude=34)
