unsupported operand type(s) for +: 'int' and 'tuple'

This error occurs when you try to perform an operation between an integer and a tuple, which is not possible as they are different data types.

For example:

a = 5
b = (1, 2, 3)
c = a + b

This will result in the error message: "TypeError: unsupported operand type(s) for +: 'int' and 'tuple'".

To fix this error, you need to make sure that you are performing operations between compatible data types. If you need to use the values inside the tuple in your operation, you can access them using indexing. For example:

a = 5
b = (1, 2, 3)
c = a + b[0]

This will set `c` to 6, as it adds the value of `a` to the first value in the tuple `b`.
