EXTRA CREDIT after the REFACTOR Challenge

""" Add a "SAVE" option to your script. Use the open function to open a file and save your shopping list to it.

Then use a for loop on the file to read each line in the file. Add each line to your shopping_list variable when your file first runs.

Your list is now more permanent! """

Did anyone do this - EXTRA CREDIT challenge - after Refactor.

The link that the "open" provides to, I tried reading it. Doesn't make sense to me :|

Hi Sachin,

For introductory stages the open() function can be called as

open('file.txt')

The additional arguments that you see in the docs all have defaults and don't have to be adjusted. There is a small chart in the docs that explains what the defaults mean, but for the purpose of the extra credit you only have to pass in the text file you're looking to open.

I hope this helps.

thanks. you're a life saver. But I still have a long way to go to be able to solve this thing. And where do i complete the EXTRA credit objective. In the refactor itself?

Unfortunately, the extra credit isn't actually extra credit. It's there to help you challenge yourself and for self-growth. You can create it in workspaces and ensure that it runs properly, and ask Kenneth, the staff, or Treehouse community to review your code for feedback.
