ValueError: Port could not be cast to integer value as

Hy, I'm created a AmazonMQ using broker as RabbitMQ. Now I want to publish a message and read that message from the queue using python. So I followed the steps given in the AWS docs.
Link: Using Python Pika with Amazon MQ for RabbitMQ
I follow the same steps in docs but when I tried to send a message to the queue it gives me this error!
Traceback (most recent call last):
File "E:/Axcer/Using-Python-Pika-with-Amazon-MQ-for-RabbitMQ/publisher.py", line 26, in

raise ValueError(message) from None

I have really no Idea about this issue! I hope that someone can help me with this. Thank you!

Sending screenshot

This is my code it should send me an email with a screenshot but instead I get the following error.
Traceback (most recent call last):

This is the code what should I do to get rid of the type error in this python2.7 code.

does anyone have any ideas

Failing to open websocket connection to IBM Watson speech to text

The following code just returns the output: "Failed to open WebSocket" Please help me correct it. I suspect the ws_url might be faulty, but still unsure.
from ws4py.client.threadedclient import WebSocketClient
import base64, time
class SpeechToTextClient(WebSocketClient):
def __init__(self):
ws_url = "wss://stream.watsonplatform.net/speech-to-text/api/v1/recognize"
username = "your username"
password = "your password"
auth_string = "%s:%s" % (username, password)
base64string = base64.b64encode(auth_string.encode())
try:
WebSocketClient.__init__(self, ws_url,
headers=[("Authorization", "Basic %s" % base64string)])
self.connect()
except: print("Failed to open WebSocket.")
def opened(self):
self.send('{"action": "start", "content-type": "audio/l16;rate=16000"}')
def received_message(self, message):
print(message)
stt_client = SpeechToTextClient()
time.sleep(3)
stt_client.close()
Error message is provided below:¨
Here is the full error message:
Traceback (most recent call last):
File "C:\Users\Vetle\Desktop\Python projects\problem.py", line 27, in
stt_client.close()

As per the API documentation you need to pass in an authentication token and not the basic service credentials. The Documentation has sample web socket code - https://www.ibm.com/watson/developercloud/speech-to-text/api/v1/#recognize_audio_websockets

AssertionError during idle_check in IMAPClient

I am attempting to have a python script that constantly monitors a gmail account for new emails. Using IMAPClient, it opens two imap connections, one in idle mode. Whenever a new message is received, the connection in idle mode tells the other connection that it should fetch new mail. The non-idle connection will fetch the mail, perform some processing, then archive the email.
The problem comes when I have many emails arriving in a short period of time, more than a few in a minute. In this case, I get an AssertionError. Below is a minimal example to reproduce the error. In addition to the imap connection, it also opens an smtp connection so that it can send the emails to itself. It will usually fail with the AssertionError at some point after 5-7 emails have been sent. The AssertionError comes in the call to idle_check.
A few short comments on running the code. It does not use OAuth, and so gmail's must be set to allow less secure apps. The "username" and "password" fields at the bottom of the script must be set. The script will also archive any emails that are currently in the inbox, and so it should not be run on a primary email account.

I am running this with Python 3.4.0, using IMAPClient 0.13. This is being run in a clean virtualenv, with no other libraries installed. Any assistance would be quite appreciated.

Twisted - SleekXMPP compatibility

I am making a XMPP middleware in python which listens on a an address(host,port) and when it receives some connection on that port, it sends a XMPP message to a jid(XMPP user) on a server.
A quick review of my setup
For networking part I am using twisted
For XMPP - SleekXMPP
XMPP server - Openfire
Now when I tried using sleekXMPP without importing anything from twistedm it was working fine.
However I i try to mix sleekXMPP and twisted in one program (by importing them) I get the follwing error.

Note that in this code, the actual networking code is commented and I am using a reqSimulator class to simulate the oncoming requests.
I tried to google for any issued but got no result. Does anybody have an idea what is wrong here?

This is due to the fact that Twisted implements inet_pton for Windows, but uses different exceptions for failures than the stdlib version.
I've fixed Sleek on github for this (master and develop branches), and there will be a new point release for it shortly.
