"Name is not defined" when running a class

[lil_e]

Hi. I'm a beginner trying to figure out why my code won't work. I'm pretty sure it's a minor detail, but I tried several time, but cannot find out why

I'm trying to make a program that runs a survey by fetching methods from another module.

Appreciate your help. Thanks.

Module with class:

class AnonymousSurvey():
    """Collect anonymous answers to a survey question."""

    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(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 responses:
            print('- ' + response)

My program:

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()

Error traceback:

Error:
Traceback (most recent call last):
  File "C:/Users/Lenovo/Documents/Python/Examples_book/Page_223_language_survey.py", line 8, in <module>
    my_survey.show_question()
  File "C:\Users/Lenovo/Documents/Python/Examples_book\survey.py", line 13, in show_question
    print(question)
NameError: name 'question' is not defined

Need to add self. in front of question in the method show_question

[lil_e]

Do you mean like this? Maybe I misunderstood because I get the same traceback as last time.

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

Error:
NameError: name 'question' is not defined

[Yoriz]

Yes that is now correct also self. is missing from responses in the method show_results but that would not cause the error shown.
What is the full error traceback?

Did you make sure you saved survey after making the change

[lil_e]

Have now edited the method show_results as well

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

Full error traceback is still the same:

Error:
Traceback (most recent call last):
  File "C:/Users/Lenovo/Documents/Python/Examples_book/Page_223_language_survey.py", line 8, in <module>
    my_survey.show_question()
  File "C:\Users/Lenovo/Documents/Python/Examples_book\survey.py", line 13, in show_question
    print(question)
NameError: name 'question' is not defined

---

I'm sorry. I see that I messed up and mixed the file names when running the code. It's working now. Thank you!

[Yoriz]

If you have made the change, the error now does not match the code

print(self.question)

does not match

Error:
File "C:\Users/Lenovo/Documents/Python/Examples_book\survey.py", line 13, in show_question
    print(question)

As stated above did you make sure you saved survey after making the changes?

[lil_e]

Everything seems to be working now. The code looks like this after saving

Thanks again!
