My Code: 

total_ask_comments = 0
for post in ask_posts:
    n =int(row[4])
    total_ask_comments +=n
    
print("Total Posts for Ask Posts: " + str(total_ask_comments))
avg_ask_comments = total_ask_comments/len(ask_posts)
print("Avg Posts for Ask Posts: " + str(avg_ask_comments))


total_show_comments = 0
for post in show_posts:
    n =int(row[4])
    total_show_comments +=n
    
print("Avg Posts for Show Posts: " + str(total_show_comments))
avg_show_comments = total_show_comments/len(show_posts)
print("Avg Posts for Show Posts: " + str(avg_show_comments))

Hi @gayletan. In both of your loops, you have post as your iteration variable, but when getting the value for the comments, you’re using row. The value of row[4] is going to be the same every time because it’s probably using the last value from a previous loop. Try changing it from row[4] to post[4] and see what happens.
