Spotify voice assistant attribute error __enter__

Hi there so I wanted to make a spotify voice assistant so I found a video on youtube and the guy just went through his code and how it works and left the source code on his github so I used that and configured it to work on my settings but i'm getting an attribute error enter with one of his lines and theres 3 files "main.py" "setup.txt" and "pepper.py" but the problem is in main so im gonna drop the code down below
main.py:
import pandas as pd
from speech_recognition import Microphone, Recognizer, UnknownValueError

audio = r.listen(source=source)
command = None
try:
command = r.recognize_google(audio_data=audio).lower()
except UnknownValueError:

print(command)
words = command.split()
if len(words) <= 1:
print('Could not understand. Try again')
continue

else:
print('Specify either "album", "artist" or "play". Try Again')
except InvalidSearchError:
print('InvalidSearchError. Try Again')
the exact error is:
Traceback (most recent call last):
File "c:/Users/Yousif/Documents/Python spotify/main.py", line 49, in <module>
with m as source:
AttributeError: __enter__

__enter__ is a python method that allows you to implement objects that can be used easily with the with statement. A useful example could be a database connection object (which then automagically closes the connection once the corresponding 'with'-statement goes out of scope):
class DatabaseConnection(object):
def __enter__(self):
# make a database connection and return it
...
return self.dbconn
def __exit__(self, exc_type, exc_val, exc_tb):
# make sure the dbconnection gets closed
self.dbconn.close()
...
The error here is caused because m = None, and None cannot be used in a with statement.
>>> with None as a:
... print(a)
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Running into error <unknown>.SaveAsFile, no solution yet found via any non-token sources for extracting files from enterprise outlook

I created the next part of the program to extract specific attatchment from my active outlook:
import win32com.client as win32
import win32com
from tabulate import tabulate
import os
def findFolder(folderName, searchIn):
try:
lowerAccount = searchIn.Folders
for x in lowerAccount:
if x.Name == folderName:
objective = x
return objective
return None
except Exception as error:
print("Looks like we had an issue accessing the searchIn object")
print(error)
return None
outlook = win32com.client.Dispatch("Outlook.Application")
ons = outlook.GetNamespace("MAPI")
one = 'email#email.nl'
Folder1 = findFolder(one, ons)
inbox = findFolder('Postvak IN', Folder1)
messages=inbox.Items
ma = [["Subject", "Sender", "Attachment", "Saved?"]]
PathName = "C:\\Temp\\CV_BU_SQ"
os.chdir(PathName)
for msg in messages:
if msg.Class == 43 and "TLS NL_Commvault" in msg.SenderName and len(msg.Attachments) == 1:
CV_file = str(msg.Attachments.Item(1))
CV_pf = os.path.join(os.getcwd() + '\\' + CV_file)
res = "Yes!"
try:
msg.Attachments.SaveAsFile(os.getcwd() + '\\' + CV_file)
except Exception as e:
res = "No, error: " + str(e)
ma.append([msg.Subject[:30], msg.SenderName[:30], CV_file, res])
print(tabulate(ma,headers="firstrow"))
The output is:
Subject Sender Attachment Saved?
------------------------- ---------------- ---------------------------------------------------- -------------------------------
Backup Job Summary Report TLS NL_Commvault Commvault***DagelijkseBackup_2021-07-23-08-00-13.csv No, error: <unknown>.SaveAsFile
or raw error:
Traceback (most recent call last):
File "C:/Users/id983857/PycharmProjects/CheckCVMail/main.py", line 37, in <module>
msg.Attachments.SaveAsFile(os.getcwd() + '\\' + CV_file)
File "C:\Users\id983857\CheckCVMail\lib\site-packages\win32com\client\dynamic.py", line 527, in __getattr__
raise AttributeError("%s.%s" % (self._username_, attr))
AttributeError: <unknown>.SaveAsFile
This outlook environment is based on Office 365, enterprise edition ...
Any e-mail extraction software demo-edition can not be tested, as this is an enterprise edition.
I do NOT need a token to read my mail per O365 or HTML, just my user account.
I don't have access to an non-enterprise O365.
I want to know what could be the reason for this error?
Any value to the SaveAsFile(...) results in the same error.
I hope somebody has a idea how to fix this.

Change the line
CV_file = str(msg.Attachments.Item(1))
to
CV_file = msg.Attachments.Item(1).FileName
and
msg.Attachments.SaveAsFile(os.getcwd() + '\\' + CV_file)
to
msg.Attachments.Item(1).SaveAsFile(os.getcwd() + '\\' + CV_file)

The Attachments property returns a collection of attachments. If you need to access the first attachment from the collection you can use the Item method:
msg.Attachments.Item(1)

How to run CANoe testmodule via Python?

I would like to be able to start a testmodule that is in my CANoe script; it works fine if I start everything without Python.
Now, my Python code can load CANoe, open the desired cfg, and start the simulation.
I tried some code from examples in the documentation and here, but it doesnt work...

IndexError: list index out of range for pyswip library

First of all I'm getting too many errors for python right now. This situation affected my motivation quite negatively. I'm trying to run an expert system that I found in this error. But I get the following error. I looked at other solutions but it didn't work for me either.

Windows Solution:
Make sure your Python and SWI Prolog are both 32- or 64-bit.
Go to line 180 of core.py and change the line to this:
paths = [os.path.join(programFiles, r'swipl\bin', dllName)

For first error:
As per official documentation of Pyswip you must take care of version of python and SWI-Prolog.
Make sure the SWI-Prolog architecture is the same as the Python architecture. If you are using a 64bit build of Python, use a 64bit build of SWI-Prolog.
For second error:
When you are accessing ret[-1] in match = pattern.match(ret[-1]) the index of list ret is not available.

AttributeError: '_pjsua.Transport_Config' object has no attribute '_cvt_to_pjsua'

I'm currently trying to use the pjsip api pjsua in python and therefor studying this Hello World example: http://trac.pjsip.org/repos/wiki/Python_SIP/Hello_World
I copied the code over, integrated account configuration according to http://trac.pjsip.org/repos/wiki/Python_SIP/Accounts etc. But when I run the sample, I get the following output:
Traceback (most recent call last):
File "/home/dmeli/workspace/eit.cubiephone.sip_test/eit/cubiephone/sip_test/hello.py", line 48, in <module>
acc = lib.create_account(acc_cfg)

err, acc_id = _pjsua.acc_add(acc_config._cvt_to_pjsua(), set_default)
File "/usr/local/lib/python2.7/dist-packages/pjsua.py", line 900, in _cvt_to_pjsua
cfg.rtp_transport_cfg = self.rtp_transport_cfg._cvt_to_pjsua()
AttributeError: '_pjsua.Transport_Config' object has no attribute '_cvt_to_pjsua'
Because I'm not really a python expert and never worked with PJSIP before, I can't really figure out the error. Too me, it looks like it's actually an error in the pjsip python wrapper. But what do I know?
Code:
lib = pj.Lib()
lib.init(log_cfg = pj.LogConfig(level=3, callback=log_cb))
transport = lib.create_transport(pj.TransportType.UDP)
lib.start()
acc_cfg = pj.AccountConfig("XXXXX", "XXXXXX", "XXXXXX")
acc_cfg.id = "sip:XXXXXXX#XXXXXXXX"
acc_cfg.reg_uri = "sip:XXXXXXXXX"
acc_cfg.proxy = [ "sip:XXXXXXXXX;lr" ]
acc = lib.create_account(acc_cfg)
# Make call
call = acc.make_call("XXXXXXXXXXX", MyCallCallback())
Line where the error happens in pjsua.py:
cfg.rtp_transport_cfg = self.rtp_transport_cfg._cvt_to_pjsua()
(rtp_transport_cfg doesn't seem to have a member _cvt_to_pjsua()??)

For further work correctly, look at the PJSIP api (pjsua.py) that he is waiting for the order and structure!!!
