Write a function that calculates the value_counts in the decade pandas column of the dataview if the rows in the rating column = 5.0 if av_rating[av_rating.rating == 5.0]: av_rating['decade'].value_counts() else: pass

def top_decade(av_rating):
  if av_rating[av_rating.rating == 5.0]:
      av_rating['decade'].value_counts()
  else:
      pass 
  return av_rating

top_decade(av_rating)
