I am receiving a NameError even though I though I had defined 'randomInt'. How would I remove this error?
(Using Python)
Transcribed Image Text:Here, define a class Kingdom().
This class should have two instance attributes: name and title , which will be strings sp
character (in that order).
This class will also have a method introduce(). This method should return (not just
'Hello, my name is Ferdinand, and I am a King.'
..where 'Ferdinand' corresponds to whatever is stored in Kingdom() object's name attrib
whatever is stored in the Kingdom() object's title attribute.
I # YOUR CODE HERE
class Kingdom():
name = 'Ferdinand'
title =
'King'
def introduce():
print('Enter name:')
name =
str(input())
print('Enter title:')
str(input())
title =
return('Hello, my name is', name,
, and I am a', title,
.')
print(introduce())
Enter name:
John
Enter title:
Prince
('Hello, my name is', 'John',
and I am a', 'Prince'
![This object should inherit all attributes and methods from Kingdom().
Additionally, the CourtJester() object should have:
• a class attribute headwear , storing the value 'fool's cap'
• a method tell_a_joke() that should return a joke at random from the list provided below
(Reminder: You imported the random module earlier. Use of a function from that module will likely be helpful in
tell_a_joke().)

NameError: name 'randomInt' is not defined
Expert Solution
Step 1: explanation:
The reason you are getting this error is because print function is in the class and not in the function.
what's happening now is:
1. class is called
2. it is asking to print a random joke from jokelist
3. it found the jokelist in main but randomint is not in the class. it is defined in function.
that is why you are getting the NameError.
