Original post: “When I assign for a item which list of single item, it seems can't set a value for item which I want to.” See the FAQ entry <https://docs.python.org/3.5/faq/programming.html#how-do-i-create-a-multidimensional-list>. When you multiply a list, each outer item is actually just reference to the same inner list object.

For future reference, don't post screen shots. Copy and paste the text of your code and its output. You don't program with Photoshop, you program with a text editor. Screen shots make it impossible to copy the code, search for the text, and make it difficult or impossible for the blind and visually impaired to contribute.
