Answer 3

#There is actually a nice usage for __repr__, because the print function often calls this, when you print the object.

class Vectors:
def __init__(self, i, j):
self.i = i
self.j = j

def __repr__(self):
return "{0}i + {1}j".format(self.i, self.j)

a = Vector(5, 7)
print(a)
#Output: 5i + 7j

It will be called as a function, when you use an object of the class as an argument to the repr builtin function.
