Python3-TypeError：列表索引必须是整数或切片，而不是str-List

Question

I've just recently started exploring Python and can't seem to figure out a way to code this. I'm guessing the fix is fairly simple. Can someone help me?

temp = 0
for i in list[::-1]:
    temp = temp + 1.11
    list[i].append("{0:.2f}".format(temp))

Answer 1

You already have the list item as i and you can just append to it. list[i] is indexing the list with the list item (which I think is another list) and not index.

So instead of

list[i].append("{0:.2f}".format(temp))

you should do

i.append("{0:.2f}".format(temp))
