Blank lines after class or function?

Why am I keep on getting the error that there needs to be 2 blank lines after a function or class?

pep.py 
import datetime


def my_func():
    return "It ran!"


sizes = ["small", "medium", "large"]


class Tree:


Tree(sizes[0], {"name": "Tulip Tree"})


def __init__(self, size, characteristics):
    self.size = size
    self.charac = characteristics
    self.roots = True
    self.leaves = 0


def grow_leaves(self):
    self.leaves += 1

The challenge checker probably got confused by too many unexpected issues, in particular:

  • the indentation is already correct and should not be changed
  • the order of lines in the class definition should not be changed
  • the quote style should be made consistent, but only the one 'odd' line should be changed
