Python-Youtube-Api : Missing code parameter in response

I am testing the python-youtube package, using the following code:
from pyyoutube import Api
api = Api(
client_id="yes-my-client-id-here-i-know",
client_secret="yes-my-client-secret-here-i-know")
authorization_url = api.get_authorization_url()
access_token = api.generate_access_token(authorization_response=authorization_url[0])
print('authorization_url : >>>>>> ', authorization_url)
print('access_token : >>>>>> ', access_token)
I get the following error.
Traceback (most recent call last):
File "main.py", line 10, in <module>
access_token = api.generate_access_token(authorization_response=authorization_url[0])
File "/Users/sleento/production/python-youtube-api/env/lib/python3.8/site-packages/pyyoutube/api.py", line 263, in generate_access_token

File "/Users/sleento/production/python-youtube-api/env/lib/python3.8/site-packages/requests_oauthlib/oauth2_session.py", line 244, in fetch_token

File "/Users/sleento/production/python-youtube-api/env/lib/python3.8/site-packages/oauthlib/oauth2/rfc6749/clients/web_application.py", line 220, in parse_request_uri_response
response = parse_authorization_code_response(uri, state=state)

raise MissingCodeError("Missing code parameter in response.")
oauthlib.oauth2.rfc6749.errors.MissingCodeError: (missing_code) Missing code parameter in response.

I solve that, I was using client_id instead of api_key parameter.
from pyyoutube import Api
api = Api(
api_key="yes-my-APi-key-here-i-know")
authorization_url = api.get_authorization_url()
print('authorization_url : >>>>>> ', authorization_url)

python SOAP with zeep, requests.exception: 403 client error

I'm trying to make a SOAP client in python using zeepSo far I've had zero luck in trying to get it to run. I keep getting the following error.
Traceback (most recent call last):

requests.exceptions.HTTPError: 403 Client Error: Forbidden (Forbidden port) for url: http://url:7104
I've tried the program with and without basic authentication.
from zeep import Client
from requests import Session
from requests.auth import HTTPBasicAuth
from zeep.transports import Transport
client_location = "file://C:/<path-to-local-file>"
loc = "<url-to-wsdl>"
session = Session()
session.auth = HTTPBasicAuth('usrname', 'pass')
transport_with_basic_auth = Transport(session=session)
client = Client(wsdl=client_location, transport=transport_with_basic_auth)
And version without Basic Auth.
from zeep import Client
from zeep.wsse.username import UsernameToken
client_location = "file://C:/<path-to-local-file>"
loc = "<url-to-wsdl>"
client = Client(wsdl=loc, wsse=UsernameToken(usr, password, use_digest=True))

I was able to solve the issue by doing the following. The issue was caused by some firewall issues and the proxy not working.
import requests
session = requests.session()
session.trust_env = False
transport = Transport(session=session)
client = Client(wsdl=client_location, wsse=UsernameToken(usr, password, use_digest=True), transport=transport)

TypeError: sequence item 0: expected str instance, bytes found
Any idea why it is happening?

This error occurs because of the difference in the way Python 2 and Python 3 handle byte strings, more details about this are available here:
https://docs.python.org/3/whatsnew/3.0.html
This issue occurs because of the way that oath2client and httplib2 handled strings as bytes - the latest version of httplib2 which is newer than the current PyPI version(as of 03/25/2015) has included a work around for this issue.
Eventually the developers might decide on a different solution to the problem, however, you can use the newer version of httplib2 to resolve this problem in your code.

Python Proxy Error With Requests Library

I am trying to access the web via a proxy server in Python. I am using the requests library and I am having an issue with authenticating my proxy as the proxy I am using requires a password.
proxyDict = {
'http' : 'username:mypassword#77.75.105.165',
'https' : 'username:mypassword#77.75.105.165'
}
r = requests.get("http://www.google.com", proxies=proxyDict)
I am getting the following error:
Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: 'h6f2v6jh5dsxa#77.75.105.165'
How do I solve this?
Thanks in advance for your help.

You should remove the embedded username and password from proxyDict, and use the auth parameter instead.
import requests
from requests.auth import HTTPProxyAuth
proxyDict = {
'http' : '77.75.105.165',
'https' : '77.75.105.165'
}
auth = HTTPProxyAuth('username', 'mypassword')
r = requests.get("http://www.google.com", proxies=proxyDict, auth=auth)

I've been having a similar problem on Windows and found the only way to get requests to work was to set the proxies as environment variables before I started Python. For you this would be something like this:
set HTTP_PROXY=http://77.75.105.165
set HTTPS_PROXY=https://77.75.105.165
You might also want to check is there's a specific port required, and if so set it after the url. For example, if the port is 8443 then do:
set HTTP_PROXY=http://77.75.105.165:8443
set HTTPS_PROXY=https://77.75.105.165:8443

You can use urllib library for this.
from urllib import request
request.urlopen("your URL", proxies=request.getproxies())

OAuth Gdata Python Client throws stacktrace on RSA_KEY

tlslite has two keyformats: PEM and XML. It first tries PEM (see parsePrivateKey), and then falls back to XML. Apparently, there is an error in your PEM file, so PEM parsing fails (but should have succeeded). Parsing XML then clearly must fail.
My guess is that you messed up line endings somehow, but perhaps there is something even more fundamentally wrong with the PEM file.
