Your error message doesn't match your command.  Now if you
typed:

list[0]+['Five']

that gives you the error you showed.

What you meant to type was:

l = ['One','Two','Three','Four']

This is a list of four strings, what you entered was a list of one
string.

NOTE never call a variable 'list' as it will mask the built-in list
method (same goes for str, tuple, int, float, etc).
