The “TypeError: unsupported operand type(s) for -: ‘str’ and ‘int’” error is raised when you try to subtract a string from an integer. You solve this error by converting all strings to integers using the int() method before performing a mathematical operation.Solution 1
If you try to subtract a string from another string contains a valid number, convert the string to an integer using the built in function int(). This will resolve the error. The built in function int() converts a string contains a valid number to an integer number.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.
