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.

<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div>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:<br><br>in the class init method I added<br>self.visited = []<br><br>and in the function where i check if city was visited:<br>cityNumber = 1 #example<br>if (not cityNumber in self.visited):<br> #do some stuff<br> self.visited[cityNumber] = "true"<br><br>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<br></div>
