I’m trying to build a program that utilizes the python-telegram-bot library with Python 3, but I’m running into an error that I find confusing when attempting to execute it. The same problem occurs even with the example codes provided. Could someone clarify the meaning of the error? Below is the specific output of my program:

Seems like you’re using an older version of urllib3 that might be conflicting. Try updating both python-telegram-bot and urllib3 to the latest versions. If that doesn’t fix it, you might want to check any overlapping libraries in your path. That helped me once when I had a similar issue.
