Firstly, you're using stack_array.py: https://bohr.wlu.ca/cp164/labs/lab02/stack_array.txt

Write and test the following function:

def array_to_stack(s, a): """ ------------------------------------------------------- Pushes contents of a onto s. Use: array_to_stack(s, a) ------------------------------------------------------- Preconditions: s - a Stack object (Stack) a - a Python list (list) Postconditions: The contents of a are moved into s, a is empty. ------------------------------------------------------- """ 

Read carefully, also there's 2 seperate modules, this is the function and you're importing it to the other module (main).

Add this function to a Pydev module named utilities in your login_data_structures project so that you have easy access to it later.

Thank you!
