When I go to run the code I get this Error: Traceback (most recent call last):
File “script.py”, line 53, in
la_arts = find_attractions(“Los Angeles, USA”, [‘art’])
File “script.py”, line 41, in find_attractions
attractions_in_city = attractions[destination_index]
UnboundLocalError: local variable ‘attractions’ referenced before assignment

I followed the video exactly after not being able to figure it out and still can’t get rid of this error.

#2

yes, sometimes the functions don’t access variables in the global namespace/scope

One way to fix fix that is to use the global keyword:

In the find_attractions function,
on a line before you use attractions,
put:
global attractions

Also, in the for-loop later in that function,
there seems to be a typo
in
for attractions in attractions_in_city:
Here, attractions should be attraction
because that’s what you’re using inside that loop.

#3

I changed the code in the for-loop from “attractions” to “attraction” and problem solved! I spent too much time analyzing and I guess missed a simple letter…thank you for the help!
