write a class in python called chair that

_init__(self,a,b,c) : Saves the arguments as attributes.

Returns ValueError if a b c are negative, or if the sum is not equal to 500

and also

__eq__(self,other) : Takes another Chair object and returns True if this Chair and that one have the same a , b , and c components. This special method provides overloading of the operator == , so that expressions like a == b and a != b will work if a and b are Chair objects
