Answer 1

yes, you have a problem in the delete function.
in the first 'else' statement, you should test if 'cur_node.left is not none and cur_node.right is none'
your code should look like this:
if cur_node.left is None and cur_node.right is None:
...
elif cur_node.left is not None and cur_node.right is None:
...
elif cur_node.right is not None and cur_node.left is None:
...
else:
#both cur_node.left and cur_node.right are not None.
...
