Hi Team
class Circle:
pi = 3.14
def __init__(self, diameter):
self.radius = diameter / 2
def area(self):
return self.pi * self.radius ** 2
def circumference(self):
return self.pi * 2 * self.radius
def __repr__(self):
return 'Circle with radius' + ' ' + str(self.radius)
medium_pizza = Circle(12)
teaching_table = Circle(36)
round_room = Circle(11460)
print(medium_pizza)
print(teaching_table)
print(round_room)
This is an exercise I have done that teaches string representation. My question is more to understand the use of this method ( and to understand it better).
-
Why does python have this dunder to get the object representation. Couldn’t the coding be made simpler if a print(object) just printed the stored value anyway, reducing a dunder.
-
If a coder needed to see the location and class data of the object he/she could call it explicitly with another command?? As a coder don’t we need the stored value more often than the default representation.
-
Do you reckon this will be improved in next python update?
-
If my questions are not that valid than how does default representation of an object valuable/ worthy in the coding or later stages?
All of this coz I was thinking its bit redundant having to call a repr dunder to get the value when the an update can easily make it straightforward. Please let me know if the community feels the same.
Thank you
