I get the following error text:

Ok, and what debugging have yo tried?

Did you try calling your methods to see what happens?

That error text is copied from FreeCodeCamps’ terminal.

I run my code in the Spyder-Ide and the output was this;

runfile(‘/home/jajarvin/.config/spyder-py3/jj/Buil_a_Media_Catalog_jj.py’, wdir=‘/home/jajarvin/.config/spyder-py3/jj’)
Media Catalogue (empty)
Media Catalogue (1 items):

  1. Dances with Wolves (1990) - 224 min, Kevin Costner

Media Catalogue (2 items):

  1. Dances with Wolves (1990) - 224 min, Kevin Costner
  2. Annie Hall (1977) - 93 min, Woody Allen

Correction! This was Spyder’s output when there was two items in self.items :

runfile(‘/home/jajarvin/.config/spyder-py3/jj/Buil_a_Media_Catalog_jj.py’, wdir=‘/home/jajarvin/.config/spyder-py3/jj’)
Media Catalogue (2 items):

  1. Dances with Wolves (1990) - 224 min, Kevin Costner
  2. Annie Hall (1977) - 93 min, Woody Allen

Didn’t you already create a string representation of a movie object? Why not use that? Not great to repeat code like this.

That said are you sure the code here is exactly the same as your other editor?

Thank you for your tip.

I modified my code and now it gives the correct output
