• # tests are all showing that I passed, yet I failed?

I would like to give some feedback about ...

HTTP_USER_AGENT:

```Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/50.0.2661.102 Chrome/50.0.2661.102 Safari/537.36
```

For this puzzle, I see the response for 8 basic tests and 11 extra tests all saying that I passed, yet, it is telling me that I failed. I don't understand why.

Here is the contents of pyramid.py if that helps.

```def count_gold(pyramid):
paths = {"0-0":pyramid}
for y in range(len(pyramid)):
line = pyramid[y]
for x in range(len(line)):
if (y +1 != len(pyramid)):
keys = [x for x in paths.keys()]
for key in keys:
if key.find("%s-%s"%(x,y)) != -1:
nY = y + 1
for dx in range(2):
nX = x + dx
newKey = key + ",%s-%s"%(nX, nY)
paths[newKey] = paths[key] + pyramid[nY][nX]
values = []
for key in paths.keys():
values += [paths[key]]
rtn = max(values)

return rtn
