My Code:
genre_type_android = categorize(android_eng_free,1)
for genre in genre_type_android:
total = 0
len_genre = 0
for row in android_eng_free:
genre_app = row[1]
n_installs = row[5]
n_installs = n_installs.replace(',','')
n_installs = n_installs.replace('+','')
n_installs = float(n_installs)
if genre == genre_app:
total += n_installs
len_genre += 1
avg_n_installs = n_installs / len_genre
print(genre, ';', avg_n_installs)

I don’t get what’s the difference between my code and solution code on GitHub(pasted below). I know my framing is difference but I am having hard time understanding where I went wrong. Are there any videos on YouTube or somewhere where I can work on this topic. Also when I run git hub’s code I get the correct answer. PLEASE HELP!!!
genre_type_android = categorize(android_eng_free,1)
for category in genre_type_android:
total = 0
len_category = 0
for app in android_eng_free:
category_app = app[1]
if category_app == category:
n_installs = app[5]
n_installs = n_installs.replace(',', '')
n_installs = n_installs.replace('+', '')
total += float(n_installs)
len_category += 1
avg_n_installs = total / len_category
print(category, ':', avg_n_installs)
