Grouping and reshaping similar columns

In this lesson, we saw how some of the columns in the Kaggle data science survey dataset were tied together, such as columns each addressing the frequency of different work challenges. We usually want to look at those variables together, but first, we need to find them and change them into a format that's easier to use. Let's try the process out with the questions around how useful the survey respondents found different platforms for learning.

The dataset multiple_choice_responses has been loaded for you.
