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!!

Treehouse Moderator 68,425 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.

Travers Geoffray
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'})

Treehouse Moderator 68,425 PointsLines 17, 18, 21, and 22 have spaces. Spaces are considered characters and are not “blank”.

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?

Treehouse Moderator 68,425 PointsAfter adding a newline, put the cursor at the end of the line and delete any spaces.

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
