POPython dictionary key error only in one specific case
text
Body
copied!<p>I have a class that stores a list of lists in a matrix style, and it can just be indexed like [x,y].</p> <p>Right now I have these set:</p> <pre><code>test_dict = {1:"cow",2:"horse"} randommap = mapArray(None, (20,20)) </code></pre> <p>random map is just filled with lists of 1s. So any index will return a 1. But here is where I get lost, maybe because of a misunderstanding about how dictionaries work:</p> <pre><code>test_dict[1] </code></pre> <p>That obviously gives back "cow" and</p> <pre><code>randommap[1,1] #or any two x,y values up to 20 for that matter </code></pre> <p>gives me a value of 1.</p> <p>But how come this gives me a key error:</p> <pre><code>test_dict[randommap[1,1]] </code></pre> <p>In isolation, indexing randommap there gives me a value of 1, so shouldn't that 1 be supplied as an index for test_dict, thus returning me "cow"?</p> <p>Update: These are the two methods I presume are causing the issue. It appears that they are returning strings instead of integers, but I don't know If I quite understand the difference between the two.</p> <pre><code>def __str__(self): return str(self.mapdata) def __repr__(self): return str(self.mapdata) </code></pre> <p>Here is the overloaded <code>__getitem__</code> method:</p> <pre><code>def __getitem__(self, (x,y)): #Just reverses it so it works intuitively and the array is # indexed simply like map[x,y] instead of map[y][x] return mapArray(self.mapdata[y][x]) </code></pre> <p>Sorry the formatting seems to have been messed up a bit.</p>
