import datetime
def my_func():
return 'It ran!'
sizes = ['small', 'medium', 'large']
class 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
Tree(sizes[0], {'name': 'Tulip Tree'})

AssertionError: Regex didn't match: 'self.leaves\\s\\+\\=\\s1[\\r\\n]{3}Tree' not found...
There should be 2 blanks lines after a function or class
So add another blank line before the instantiation of Tree and it should pass.
BTW, though the checker is looking for "at least x lines", in cases of the methods, one blank line is sufficient. A handy local function to have is pycodestyle that checks all the syntax.
$ pip install pycodestyle
$ pycodestyle your_code.py
$ pycodestyle your_code.py
your_code.py:14:5: E303 too many blank lines (2)
your_code.py:21:5: E303 too many blank lines (2)
your_code.py:24:1: E305 expected 2 blank lines after class or function definition, found 1
Post back if you have more questions. Good luck!!

Python Development Techdegree Graduate 26,967 PointsChris - thank you so much for your help! Unfortunately, I'm still getting the same error after adding another blank line before the instantiation of Tree....

Treehouse Moderator 68,441 PointsDid you add the blank line marked my >>> below? Be sure the editor didn’t add any spaces on the line.
def grow_leaves(self):
self.leaves += 1
>>>
Tree(sizes[0], {'name': 'Tulip Tree'})
If your still getting the error please repost your latest code.

Python Development Techdegree Graduate 26,967 PointsI did, I think I'm doing it correctly...here's the code:
import datetime
def my_func():
return 'It ran!'
sizes = ['small', 'medium', 'large']
class 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
Tree(sizes[0], {'name': 'Tulip Tree'})

Travers Geoffray
Python Development Techdegree Graduate 26,967 PointsAh okay...how do I make the line blank instead of a space? I'm just using return key to separate the lines of code. Is that the wrong way to do it?
Chris Freeman
Treehouse Moderator 68,441 PointsAfter adding a newline, put the cursor at the end of the line and delete any spaces.
Travers Geoffray
Python Development Techdegree Graduate 26,967 PointsThat did it, thank you Chris! I appreciate your patience.

Python Development Techdegree Graduate 8,556 PointsWith PEP8 you only need one blank line After each method within a class, so the blank lines between "class Tree:" and your first def are not needed as well as only one blank line between self.leaves = 0 and your second def. Lastly each function/class needs to be separated by two blank lines which means you'll need to add another line above "Tree(sizes...." A good way to think of blank lines are like breathing/brake points when speaking/writing, it gives your mind and eyes a rest and helps differentiate between sections of code. Hope this helps:D
