Which methods will trigger an action that will evaluate a DataFrame? (Select TWO)

Show Suggested Answer Hide Answer
Suggested Answer: B, E

The methods that will trigger an action that will evaluate a DataFrame are DataFrame.collect() and DataFrame.show(). These methods will force the execution of any pending transformations on the DataFrame and return or display the results. The other options are not methods that will evaluate a DataFrame. Option A, DataFrame.random_split(), is a method that will split a DataFrame into two or more DataFrames based on random weights. Option C, DataFrame.select(), is a method that will project a set of expressions on a DataFrame and return a new DataFrame. Option D, DataFrame.col(), is a method that will return a Column object based on a column name in a DataFrame.

I heard the correct answers are A and E. Something about random splits and showing the DataFrame. But who knows, I'm just winging it.

Hold on, I thought the answer was supposed to be B and E. Isn't 'collect' the way to actually evaluate a DataFrame?

Hmm, I'm not so sure. Maybe C and D? Selecting columns and getting column information could work too.

B and E, for sure. Collecting the DataFrame and displaying it are obvious choices.

I think A and E are the correct answers. Splitting the DataFrame and showing the results would definitely trigger an evaluation.
