__repr__

magic methods

The method repr(obj) and the console call: an unambiguous representation of the object for developers.

Syntax

def __repr__(self) -> str: ...

A good __repr__ looks like the expression that recreates the object: Point(1, 2). It also serves as the fallback __str__, which is why it is the one to define first. The built-in default prints <__main__.Point object at 0x…>, useless in both debugging and logs.

Examples

class Point:
    def __init__(self, x, y):
        self.x, self.y = x, y
    def __repr__(self):
        return f'Point({self.x!r}, {self.y!r})'
p = Point(1, 2)
print(repr(p))  # → Point(1, 2)
print(p)  # → Point(1, 2) — __str__ нет, взят __repr__
print(f'{p!r}')  # → Point(1, 2)
