My Code:
row_1 = [‘Facebook’, 0.0, ‘USD’, 2974676, 3.5]
row_2 = [‘Instagram’, 0.0, ‘USD’, 2161558, 4.5]
row_3 = [‘Clash of Clans’, 0.0, ‘USD’, 2130805, 4.5]
row_4 = [‘Temple Run’, 0.0, ‘USD’, 1724546, 4.5]
row_5 = [‘Pandora - Music & Radio’, 0.0, ‘USD’, 1126879, 4.0]
fb_rating_data = row_1[0], row_1[3], row_1[-1]
insta_rating_data = row_2[0], row_2[3], row_2[-1]
pandora_rating_data = row_5[0], row_2[3], row_2[-1]
avg_rating = (fb_rating_data[3] + insta_rating_data[3] +
pandora_rating_data[2]) / 3
The answer
row_1 = [‘Facebook’, 0.0, ‘USD’, 2974676, 3.5]
row_2 = [‘Instagram’, 0.0, ‘USD’, 2161558, 4.5]
row_3 = [‘Clash of Clans’, 0.0, ‘USD’, 2130805, 4.5]
row_4 = [‘Temple Run’, 0.0, ‘USD’, 1724546, 4.5]
row_5 = [‘Pandora - Music & Radio’, 0.0, ‘USD’, 1126879, 4.0]
fb_rating_data = [row_1[0], row_1[3], row_1[-1]]
insta_rating_data = [row_2[0], row_2[3], row_2[4]]
pandora_rating_data = [row_5[0], row_5[3], row_5[4]]
avg_rating = (fb_rating_data[2] + insta_rating_data[2] + pandora_rating_data[2]) / 3
Im confused, I thought this would be the correct answer but when I viewed the answer they were calling the second element when the question says to add the ratings together, calling the second element doesent make sense to me, could anyone enlighten me on this
