JSON Error

[dc500]

I figured out the issue with the pip install pattern and I manually updated all the code from python 2 to python 3. Now my headache is:

How do I fix this?

Hello, I was playing around with this code just now. And I got the same error. This error simply means there is nothing fed into the JSONDecoder. So I checked for possible solutions and find out this API were actually retired on April 10, 2018, according to this page: https://developers.google.com/qpx-express/. So the API was not responding with anything which causes this error. We will probably have to look for an alternative API. I am trying to see if skyscanner API. Not sure if this would work.
