Write a function that calculates the value_counts in the decade pandas dataframe column 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 value_counts(df, year):
    if df[df['rating'] == 5.0]:
        return df["year"].value_counts()
    else:
        return "no movie with 5.0 rating in this year"
