3. Write and test the following function that uses a Stack: 1 def stack_reverse(source): """ 2 3 4 Reverses the contents of a stack. 5 Use: stack_reverse(source) 6 7 Parameters: 8 source - a Stack (Stack) 9 Returns: 10 None 11 """ 12 Add the function to a PyDev module named functions.py. Test it from t03.py. This function uses a stack, meaning you may manipulate the stack using only the stack interface methods: push, pop, is_empty, and peek. You may not use or refer to the internal Stack elements such as_values.
