C1M1_Assignment: Exercise 1-A: NameError: name 'test_your_code' is not defined

After correctly defining variables for line one tap Shift + Enter, I select line two, tap Shift + Enter and get the following error:

NameError                                 Traceback (most recent call last)
Cell In [3], line 2
      1 # Test your code!
----> 2 test_your_code.exercise_1a(book_title, author, year_published, available_copies)

NameError: name 'test_your_code' is not defined

Chatbot reports the following:

test_your_code as something that has been defined or imported in your code.

When and where do I import or define test_your_code.exercise_1a??

This is having a downstream affect:
but I am getting a name error.

print(f"Title: {book_title}")
print(f"Author: {author}")
print(f"Published: {year_published}")
print(f"Available Copies: {available_copies}") 

But I am getting the following error:

NameError: name 'available_copies' is not defined

Hi @0gsl, welcome! I tried reproducing the error you are getting, and I think it is likely happening because you haven’t run the first line of code in the assignment (“import test_your_code”), and later steps cannot find the necessary Python module. If you go to the beginning of the assignment, there is a section called Before you begin, and you should run that line first, so that it imports the tests. Please let me know if this helps.

Thank you so much, that was the issue!
