I am using python slack module to send a message to a slack channel and i have also installed all the required modules (slack, slackClient, openssl) as well but I am facing with SLL violation. I am not sure if it is related to proxy or not. Any help would be appreciated.
code:
import slack
import ssl
SLACK_API_TOKEN = "xoxb-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
client = slack.WebClient(token=SLACK_API_TOKEN)
response = client.chat_postMessage(
channel='#channelName',
text="testing")
if (response["ok"]):
print("Notification sent to Slack")
Error:

I think this error was caused by ssl.
How can I solve this error?
Your problem is caused by using unsupported Python packages. The package urllib uses APIs (TCP Sockets) that do not exist in the browser. This is not a limitation of PyScript, no browser application can use socket-based APIs.
The solution is to use supported APIs such as fetch or pyfetch.
I'm trying to upload example from dash documentation.
When I try (with PyCharm)
df = pd.read_csv(
'https://raw.githubusercontent.com/plotly/datasets/master/solar.csv'
)
I get these errors.
But when I try the same code with Anaconda Jupyter it works fine. It means problem is not in my OS but in PyCharm.
Can you advise what should I do?

I think you should check whether you're using the same Python interpreter and Pandas version in both Jupyter and PyCharm.
Find Jupyter interpreter: How to know which Python is running in Jupyter notebook?
(Check this if using Spyder: https://docs.spyder-ide.org/current/faq.html#using-existing-environment)
Check if it's the same in PyCharm: https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#interpreter
