Class code problem from CS Dojo YouTube

[snippsat]

Can copy code under from YouTube link.

class Robot:
    def __init__(self, name, color, weight):
        self.name = name
        self.color = color
        self.weight = weight

    def introduce_self(self):
        print(f"My name is " + self.name)

# r1 = Robot()
# r1.name = "Tom"
# r1.color = "red"
# r1.weight = 30
#
# r2 = Robot()
# r2.name = "Jerry"
# r2.color = "blue"
# r2.weight = 40


r1 = Robot("Tom", "red", 30)
r2 = Robot("Jerry", "blue", 40)

r1.introduce_self()
r2.introduce_self()

Output:
My name is Tom
My name is Jerry

So it's working.

Code over do i think is part-2,as you see some code is comment out.
To use comment out code it would be like this,also trow i in f-string.

class Robot:
    def introduce_self(self):
        print("My name is {self.name}")

Use:

>>> r1 = Robot()
>>> r1.name = "Tom"
>>> r1.color = "red"
>>> r1.name
'Tom'
>>> r1.introduce_self()
My name is Tom

So here is manually making the __init__ method in part 2.
