What is from rnn_utils import *

In Course 5 Week 1 Assignment 1, what is the meaning of the ‘*’ while importing?

from rnn_utils import *

What are we importing exactly?

Please read this link on import

If the list of identifiers is replaced by a star ('*' ), all public names defined in the module are bound in the local namespace for the scope where the import statement occurs.

I recommend you take a course on python programming.

You can also open the file rnn_utils.py and see for yourself the functions that are contained there. There is a topic about that on the DLS FAQ Thread.
