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

This error occurs when you try to subtract two tuples using the minus operator (-), which is not supported in Python.

For example, if you have two tuples:

a = (1, 2, 3)
b = (4, 5, 6)

and you try to do:

c = a - b

Python will raise a TypeError because you cannot subtract one tuple from another.

To fix this error, you need to either use a different operator (such as + for concatenation) or convert the tuples to another data type that supports subtraction (such as lists or arrays).
