can anyone shed some more light on the magic method __repr__ pls

Question

__repr__

Answer 1

The __repr__ method affects how the object is represented when you try to print it.

Example:
class Complex:
def __init__(self, re, im):
self.re = re
self.im = im
def __repr__(self):
return "({} + {}i)".format(self.re, self.im)
c1 = Complex(2, 3)
print(c1)

Try removing the __repr__ of the example to see the difference.

Answer 2

the print output for this, with the __repr__ is

(2 + 3i)

without the __repr__ it produces an error because there are no methods etc to print

simply put, __repr__ allows you to create/format "how" you want the print() function to display your class's output.

so, from the above example

....
def __repr__(self):
return "({} + {}i)".format(self.re, self.im)

prints

(2 + 3i)

if you change it to

....
def __repr__(self):
return "{} plus {}".format(self.re, self.im)

it will print

2 plus 3

instead.
I hope this has made it clearer for you
