Skyroute Graph Search issues at the last steps

Here is the code below before I continue.

So I actually breezed through it. It was fairly long but as a general rule this was a lot easier than I anticipated it would be. However when I did the last steps, and finally ran the code it gave me the following error message:

BlockquoteTraceback (most recent call last):
File “skyroute.py”, line 109, in
skyroute()
File “skyroute.py”, line 20, in skyroute
new_route()
File “skyroute.py”, line 62, in new_route
start_point, end_point = set_start_and_end(start_point, end_point)
File “skyroute.py”, line 57, in set_start_and_end
start_point = get_start()
File “skyroute.py”, line 24, in get_start
start_point_letter = input("Where are you coming from? Type in the corresponding letter: ")
File “”, line 1, in
NameError: name ‘a’ is not defined

So I know it is showing where the errors are… but I am stumped as to where to find it. Unlike other projects, I want to actually work on improving it and doing the extras instead of the bare minimums. I really want to get my learning going. If I didn’t have a full-time job I was planning on becoming employable by this time. :frowning:

@salimfarhat,

Are you running this in Codecademy’s online environment or on your own computer?

I downloaded your code and it runs fine on my computer.
