I tried doing this but it still didnt work
```
class CryptoTicker(widget.CryptoTicker):
def fetch(self, url):
req = Request(url, self.data, self.headers)
res = urlopen(req)
charset = res.headers.get_content_charset()
body = res.read()
if charset:
body = body.decode(charset)
if self.json:
body = json.loads(body)
if self.xml:
body = xmlparse(body)
return body
def poll(self):
if not self.parse or not self.url:
return "Invalid config"
_, min = map(int, time.strftime("%H %M").split())
try:
body = self.fetch(
self.QUERY_URL.format(
self.cryptos[min % len(self.cryptos)], self.currency
)
)
except URLError:
return "No network"
try:
text = self.parse(body)
except Exception:
logger.exception("got exception polling widget")
text = "Can't parse"
return text
```
