You'll find some other errors in your code after you 
fix the string problem.  I'll leave them for you to find
since they're pretty obvious.

But one I'll mention because it is easy to miss because 
it produces wrong results rather than an error.

Try running your program with the input: 5, 5, 1 (which 
shouldn't be a triangle).

int() *returns* the int value of naa, but doesn't change 
the value of naa which remains a string.

   naa = int (input ('type first integer\n'))

is still three steps but a little more concise.

Other ways are to put one input() call inside a loop
that runs three times, saving each input in an array.

Or you could read one string containing three numbers 
in one input statement, then split them into separate 
numbers.

These may require python stuff you haven't gotten to 
yet though.
