Reload original assignment in jupyter

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

In Neural Networks and Deep Learning Week 4, I am starting on the last programming assignment. But I did something that deleted part of the assignment on my notebook. How do I start over again with the notebook to get back the assignment in its original form?

Also, the assignment says to use my functions from the previous assignment, “Building Your Deep Neural Net Step by Step.” I assume that means I can copy just copy the functions from the previous assignment. If I do that, is there a code block in the new assignment that I can copy them into?

Read this to get a fresh copy of your assignment.

You don’t need to copy your code from the previous assignment. You just need to call the functions. For example, in the previous assignment, you did code for, let’s say cost_function, but now just use that name to call the function. All the names are given to use in this assignment.
