Say you type 42 when you run your script. Then the above assignment is
effectively
attributes["strength"] = "42"
and when you loop over the values you try to add a string to an integer
which is what Python complains about:
>>> 42 + "42"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'
To get an integer you have to convert the string explicitly:
>>> 42 + int("42")
84
The best place to do that is as early as possible, even before you put the
value into the dictionary:
attributes["strength"] = int(input(...))
(In a real application you'd guard against values that cannot be converted
to integers)
