Python: How to iterate over rows that have more than one variable?

manpreet Best Answer 2 years ago

I have a data frame like this:

tags                               views

['technology', 'science', 'art']    360
['global issue', 'energy']          670
['environment', 'technology']       800
['university', 'technology']        690

I used a method to find the most repeated tag (like here the most repeated tag is 'technology'). Now I want to calculate the total number of views for that tag. For example, here for 'technology', I should have the sum of 360+880+690 I should find rows in views related to that tag and sum the numbers.

How should I do that?
