thanks for your help

Hello @javadfarah,

you might want to refactor your Exception-handling as you built a loop that caused a stack overflow.

For example you could replace lines 295 up until 300 with:

retries = 5
for retry in range(1, retries + 1):
  try:
    response = self.s.request("get", link, timeout=2).data
  except Exception as err:
    print("Failed to fetch data from {url} [{retry}/{retries}]: {err}".format(
      url=url, retry=retry, retries=retries err=repr(err)))
    time.sleep(retry)
  else:
    break
else:
  print("Failed %s times to fetch data from %s" % (retries, url))
  return

Good luck!

hello @das7pad thank you for reply but i want to send a correct answer to my user! i cannot tel him i'm sorry test again! so i should make a loop until get sightly response

[das7pad]

You could increase the retries value to 10000 - even a while True loop has the same effect. It is a solution for the shown error as the retries do not stack anymore, they stay at the same level.
