TwilioQuest - -帮助，我的代码。 Python class 叫西铁城

Question

What am I missing in my code? I've tried different variations of this code, maybe five. I've run the code and I get the statement to execute, but there is still something missing. The name doesn't print along with it. Attached is a screenshot of the parameters that were given.

class Citizen:
  """
  this class is to describe a citizen of the City of Python
  """   
def __init__(self, first_name, last_name): 
    self.first_name = Rey
    self.last_name = Rizo
def full_name(x):
    x = self.first_name + self.last_name
def greeting(greet):
    full_name = raw_input(full_name)
    return greet + x
print("For the glory of Python!")

Answer 1

class Citizen:
    """
    this class is to describe a citizen of the City of Python
    """   
    def __init__(self, first_name, last_name): 
        self.first_name = first_name
        self.last_name = last_name
    def full_name():
        return self.first_name + self.last_name

    def greeting(greet):
        return greet + self.full_name()

When you initiate a new citizen, use:

citizen = Citizen(“first_name”, “last_name”)

To print the name:

print(citizen.full_name)

To greet:

print(citizen.greeting(“Hello”))

Answer 2

class Citizen:
    "this class is to describe a citizen of the City of Python"   
    def __init__(self, first_name, last_name): 
        self.first_name = first_name #this is an instance variable
        self.last_name = last_name
    def full_name(self):    #This is an instance method
        return self.first_name + " " + self.last_name  #This took the 2 instance variables and put them together
    greeting = "For the glory of Python!"

This is what worked for me.

Answer 3

class Citizen:
    """a citizen of the City of Python"""

    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name


    def full_name(self):
        return (f'{self.first_name} {self.last_name}')

    greeting = 'For the glory of Python!'

This worked for me.
