Create array of json objects from for loops

Question

Im attempting to extract values from an html and then convert them into a json array, and so far I have been able to get what I want, but only as separate strings:

I did two for loops:

for line in games_html.findAll('div', class_="product_score"):
  score= ("{'Score': %s}" % line.getText(strip=True))
  print score

for line in games_html.findAll('a'):
  title= ("{'Title': '%s'}" % line.getText(strip=True))
  print title

Which produce these two outputs:

{'Title': 'Uncanny Valley'}
{'Title': 'Subject 13'}
{'Title': '2Dark'}
{'Title': 'Lethal VR'}
{'Title': 'Earthlock: Festival of Magic'}
{'Title': 'Knee Deep'}
{'Title': 'VR Ping Pong'}

and

{'Score': 73}
{'Score': 73}
{'Score': 72}
{'Score': 72}
{'Score': 72}
{'Score': 71}
{'Score': 71}

(they are longer but you can get an idea with this...)

How can I use python to create a json array out of these that would look like:

[{'Title': 'Uncanny Valley', 'Score': 73}, {....}]

I am gonna use the resulting array to do other things afterwards....

Do I need to store the items from the loop into lists and then merge them? Could you please illustrate an example given my scenario?

Help is much appreciated, this is a really cool learning experience for me as I have only used bash until now. Python looks way sexier.

You need to maintain two lists for scores and titles and append all the data to those lists, instead of printing, and then zip those lists along with list comprehension to get the desired output as :

import json
scores, titles = [], []
for line in games_html.findAll('div', class_="product_score"):
    scores.append(line.getText(strip=True))

for line in games_html.findAll('a'):
    titles.append(line.getText(strip=True))

score_titles = [{"Title": t, "Score": s} for t, s in zip(titles, scores)]
print score_titles
# Printing in JSON format
print json.dumps(score_titles)
