Need help understanding where I've gone wrong

Hi, I’m trying to figure out where my mistake is and I don’t see one. It’s probably super simple and I’m dumb but if any one could possible help me out that would be amazing

Thanks in advance

the following code is what was provided and tweaked by myself

total = 2048 + 4357 + 97658 + 125 + 8

files = 5

average = total / files

print("The average size is" + str (average))

and this is the error code I’ve received 

Here is your output:The average size is20839.2Your calculation is right. However, your code does notoutput the given message.

it seems to be a simple fix but I’ve been looking over it for 20 min and still need help would love it if you smart people out there could help me out thanks
