gistfile1.py

class Point:
    def __init__(self, x, y):
        self.x, self.y = x, y

    @classmethod
    def polar(cls, r, theta):
        return cls(r * cos(theta),
                   r * sin(theta))

point = Point.polar(r=13, theta=22.6)

theta=22.6

(Looks like the gist comment doesn't want to preserve my spacing). Suggestion: Line up the r * sin(theta) under r * cos(theta)
to conform to PEP 8.

The arguments for polar should be named (line 6) to match the call on line 10. Better yet, the call on line 10 should be changed to have positional arguments so that it matches the original constructor for Point

missed one underscore on the second line

Fixed. Thanks for the suggestions!
