Need help on error type

Hello everyone,

Juste started learning python few days ago, I can’t understand my mistake here:

Can someone help me on that ?

It is complaining that total is an int, i is a str and it doesn’t know how to add them.

You could do total += int(i). The int(i) would turn the str i into an int, if it can be turned into one.

Is that

[‘7.1’, ‘7.22’, … ]

the ratings? If so, them maybe you don’t want int, but float. In that case, maybe do

total += float(i)
