Doubt in the book Python on a Crash Course

Question

I’m studying the book Python on a Crash Course And everything was going great until now. After testing the codes on pages 324 and 325 (which are a module and a program that uses it), I was surprised that nothing works.

What to do to fix this code and make it work?

Here is the module survey.py:

class AnonymousSurvey():

    def __init__(self, question): #Aqui Esta em vermelho(problema)
        #Armazena uma pergunta e se prepara para armazenar asrespostas.
        self.question = question
        self.responses = []

    def show_question(self):
        #Mostra a pergunta da pesquisa.
        print(question) #Aqui também esta (aparente problema)

    def store_response(self, new_response):
        #Armazena uma única resposta da pesquisa.
        self.responses.append(new_response)

    def show_results(self):
        #Mostra todas as respostas dadas.
        print("Survey results:")
        for response in responses:
            print('- ' + response)

And here’s the little program that uses the module above:

from Modulo_Survey import AnonymousSurvey
# Define uma pergunta e cria uma pesquisa
question = 'What language did you first learn to speak?'
my_survey = AnonymousSurvey(question)


# Mostra a pergunta e armazena as respostas à pergunta
my_survey.show_question()
print("Enter 'q' at any time to quit.\n")
while True:
    response = input("Language: ")
    if response == 'q':
        break
my_survey.store_response(response)


# Exibe os resultados da pesquisa
print("\nThank you to everyone who participated in the survey!")
my_survey.show_results()

Answer 1

On the fifth and sixth line they declare self.question and self.responses. However, when referencing them later, on lines 10 and 19, they use question and responses. Just exchange them for self.question and self.responses. In addition, the my_survey.store_response(response) has to be indented. Here’s the corrected code:

Filing cabinet survey.py:

class AnonymousSurvey():

    def __init__(self, question):
        """Store a question, and prepare to store responses."""
        self.question = question
        self.responses = []

    def show_question(self):
        """Show the survey question."""
        print(self.question)

    def store_response(self, new_response):
        """Store a single response to the survey."""
        self.responses.append(new_response)

    def show_results(self):
        """Show all the responses that have been given."""
        print("Survey results:")
        for response in self.responses:
            print('- ' + response)

Filing cabinet language_survey.py:

from survey import AnonymousSurvey

# Define a question, and make a survey.
question = "What language did you first learn to speak?"
my_survey = AnonymousSurvey(question)

# Show the question, and store responses to the question.
my_survey.show_question()
print("Enter 'q' at any time to quit.\n")
while True:
    response = input("Language: ")
    if response == 'q':
        break
    my_survey.store_response(response)

# Show the survey results.
print("\nThank you to everyone who participated in the survey!")
my_survey.show_results()
