name = input('Enter name here:') pyc = input('enter pyc :') tpy = input('enter tpy:') percent = (pyc / tpy) * 100; print (percent) input('press enter to quit')
whenever i run this program i get this
TypeError: unsupported operand type(s) for /: 'str' and 'str'
what can i do to divide pyc by tpy?
The Python "TypeError: unsupported operand type(s) for /: 'list' and 'int'" occurs when we try to use the division / operator with a list and a number. To solve the error, figure out how the variable got assigned a list and correct the assignment, or access a specific value in the list.
The Python "TypeError: unsupported operand type(s) for -: 'str' and 'str'" occurs when we try to use the subtraction - operator with two strings. To solve the error, convert the strings to int or float values, e.g. int(my_str_1) - int(my_str_2) .
The Python "TypeError: unsupported operand type(s) for /: 'str' and 'int'" occurs when we try to use the division / operator with a string and a number. To solve the error, convert the string to an int or a float , e.g. int(my_str) / my_num .
The TypeError: unsupported operand type(s) for +: 'int' and 'str' error occurs when an integer value is added with a string that could contain a valid integer value. Python does not support auto casting. You can add an integer number with a different number. You can't add an integer with a string in Python.
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 can't 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
