Well, to quote firefox: this is embarrassing. I've realized the dictionary
initialization is wrong, as [] means its a tuple, I should use {}. That's why I
don't like working nights..it's only in the morning when you start seeing
things
better. I apologize for the mail. Cheers

Subject: dictionary error: list assignment index out of range
Hy everyone, I'm trying to learng python for a week or two and there's a thing
that is really disturbing me as I do not understand what the problem is. I'm
trying to use a dictionary to remember when a user has visited a city. Code is
really basic:
in the class init method I added
self.visited = []
and in the function where i check if city was visited:
cityNumber = 1 #example
if (not cityNumber in self.visited):
#do some stuff
self.visited[cityNumber] = "true"
Apparently the last line causes the error: list assignment index out of range.
I
read that this is the simplest way to assign a value to a
dictionary(dict[key]=value). So why is the error appearing?? Thanks a lot in
advance
