python – TypeError: unsupported operand type(s) for /: str and str

python – TypeError: unsupported operand type(s) for /: str and str

By turning them into integers instead:

percent = (int(pyc) / int(tpy)) * 100;

In python 3, the input() function returns a string. Always. This is a change from Python 2; the raw_input() function was renamed to input().

The first thing you should do is learn to read error messages. What does it tell you — that you cant use two strings with the divide operator.

So, ask yourself why they are strings and how do you make them not-strings. They are strings because all input is done via strings. And the way to make then not-strings is to convert them.

One way to convert a string to an integer is to use the int function. For example:

percent = (int(pyc) / int(tpy)) * 100

python – TypeError: unsupported operand type(s) for /: str and str

I would have written:

percent = 100
while True:
     try:
        pyc = int(input(enter pyc :))
        tpy = int(input(enter tpy:))
        percent = (pyc / tpy) * percent
        break
