Error with SSL certificate when using Python shell

Question

I get errors when I use Python's requests.get to get info from any site:

Traceback (most recent call last):   File "C:\Users\ADMIN\AppData\Local\Programs\Python\Python37\lib\site-packages\urllib3\connectionpool.py", line 603, in urlopen

Also when I use pip install, there is the same error:

You are using pip version 19.0.3, however version 19.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I tried to make site URL trusted with

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org pip setuptools

but I've got nothing.

I use Windows 8, Python 3.7.4, and pip 19.0.3.

I know that I can ignore SSL verification using

r = requests.get(url = URL, verify=False)

but I still cannot use pip install now and would rather not need to consistently ignore these errors.

Make these changes to your code, and it should work :

from urllib3.exceptions import InsecureRequestWarning
.
.
.
requests.packages.urllib3.disable_warnings(category=InsecureRequestWarning)
r = requests.get(url=URL, verify=False)
