Pygame sprite file error - python-2.7

Question

Disclaimer: I'm only 10 years old so please be patient with me please :D
So I'm working on this game in pygame where you play as a balloon and you have to avoid obstacles and collect points. The points add 10 to your score and the obstacles restart your game. You use the arrow keys to move. It's based off Ski-Free. But whenever I run it I don't get an error in my script, but an error in the sprite.py file that pygame comes with. For info, I use Mac OSX Sierra as my OS and IDLE 2.712 as my shell. I use python 2. So, here's my error:
Traceback (most recent call last):
File "/Users/------------/Desktop/Sky Balloon.py", line 75, in <module>
create_map()
File "/Users/------------/Desktop/Sky Balloon.py", line 58, in create_map
obstacles.add(obstacles)
File "/usr/local/lib/python2.7/site-packages/pygame/sprite.py", line 142, in add
self.add(*group)
TypeError: add() argument after * must be an iterable, not ObstacleClass
P.S. I did cover up my but the number of characters is still the same.
Now here's my actual game script. (Sky Balloon.py)

Thank You!

Answer 1

obstacles.add(obstacle) not obstacles.add(obstacles) (extra s)
