TypeError: unsupported operand type(s) for -: 'list' and 'tuple'

This error occurs when you try to subtract a tuple from a list or vice versa.

For example:

list1 = [1, 2, 3]
tuple1 = (4, 5, 6)

result = list1 - tuple1

This will raise a TypeError because you cannot subtract a tuple from a list.

To avoid this error, make sure you are performing operations between objects of the same type. If you need to convert one type to another, use the appropriate conversion function. For example, you can convert a list to a tuple using the `tuple()` function:

list1 = [1, 2, 3]
tuple1 = (4, 5, 6)

result = tuple(list1) - tuple1
