class Robot:
def introduce_self(self)
print("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.introduce_self()
r2.introduce_self()
With the above code, copied from the YouTube channel of CS Dojo, I get a traceback
"name 'r1' is not defined.
indentation is incorrect

I typed in the code and didn't do the indents. I'm rather new to this forum, and didn't realize that using the python thingy wouldn't do the job. Anyway, when it's properly indented in Jupyter Notebook, it throws a Traceback.
Never mind. I didn't refresh a block of code after making changes, thus giving me the "name not found" error.
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.
