The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.
Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.
However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.
I’d say both techies are correct.
Volatility, as applied in gasoline, is quantified by the tendency of the liquid to change to vapor at any given temperature (vaporize). This rate of change might be hard or easy, this depends on the temperature or the pressure. Technician B is also correct. RVP is defined and determined experimentally according to the ratio of the vapor volume to the liquid volume at 100 °F.
