将python2转换成python3代码

Question

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

def __str__(self):
    return '({}, {})'.format(self.x, self.y)

points = [Point(9, 2), Point(1,5), Point(2, 7), Point(3, 8), Point(2, 5)]
sorted_points = sorted(
points,
lambda (x0, y0), (x1, y1): x0 - x1 if x0 != x1 else y0 - y1,
lambda point: (point.x, point.y))

print(', '.join(map(str, sorted_points)))
#预期结果为(1, 5), (2, 5), (2, 7), (3, 8), (9, 2)

Answer 1

init 变成 init
str 变成 str
