It tells robot takes no argument in below code can anybody tell me what's wrong in the code?

Question

class Robot:
def _init_ (self, name, color, weight):
self.name = name
self.color = color
self.weight = weight
def introduce_self(self):
print("My name is " + self.name)
r1 = Robot("Tom", "red", 40)
r2 = Robot("Jerry", "blue", 30)
r1.introduce_self()
r2.introduce_self()

Answer 1

The error is that Robot() takes no argument, but why?
It is because the constructor function is a special method. In Python, special methods are written with two underscores before and after.
It is __init__ not _init_
Check it in the code play ground.

Answer 2

Check the code again _init_ is already written.

Answer 3

Ashish Singh Check my comment again, it is __init__ not _init_

Answer 4

Again same error

Answer 5

It works in here
The only modification made is the one mentioned above: "__init__"
