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[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
What I expected to happen:
why is the number 2 in the brackets following the last line of code? what does the number represnt?:
fb_rating_data[2] + insta_rating_rating[2] + pandora_rating_data[2]
Also, why is there a negative -1 being used as a index then its switched up to a 4? i know they represent the same list item but it is quite confusing
