Overcoming SSL: CERTIFICATE_VERIFY_FAILED on Windows 10 when using urllib3

Question

This simple code in Python displays Ascii art and is taken from the following quora response: https://qr.ae/TWNB4S. I have Python version 3.7.3 installed on my Windows 10 laptop via independent installer from python.org and also via anaconda suite. The code runs fine on Jupyter notebook launched via anaconda. But when I run the same code via pycharm IDE I get SSL related errors.

I searched online for this Error but could not find a way to resolve this on my Windows 10 python 3.7.3 installation. But it works fine on my Anaconda python 3.7.3 version. So is there a way to overcome this Error? Code:

import ascii
output =  ascii.loadFromUrl("https://i.dailymail.co.uk/i/pix/2015/09/01/18/2BE1F43200000578-0-image-a-17_1441127603656.jpg")
print(output)

The Errors when I run the above code via Pycharm IDE:

Traceback (most recent call last):

If you haven't already, you can try installing the certifi package from pip. Otherwise, there are a number of solutions here, some of which cover how to make sure you have your certificates installed and others which show how to disable certificate verification.
