Python TypeError: unsupported operand type(s) for /: 'str' and 'float'

Question

My code:

total=tef+tpf-price

I\'ve got this error:

  total=tef+tpf-price
unsupported operand type(s) for -: \'float\' and \         


        

Answer 1

The only way that error could occur is if price is a string. Make price a float or an integer (depending on what you want) to fix the problem.

Either this:

tef=float(price)*5/100.0

or this:

tef=int(price)*5/100.0

Notice that, in Python, to preform an operation between two objects, those object must be of the same type (and support the operation of course).
