Solve the following python programming problem given the following code:
# Create the data class

class Data(Dataset):
    
    # Constructor
    def __init__(self):
        self.x = torch.arange(-2, 2, 0.1).view(-1, 1)
        self.y = torch.zeros(self.x.shape[0])
        self.y[(self.x > -1.0)[:, 0] * (self.x < 1.0)[:, 0]] = 1
        self.y[(self.x >= 1.0)[:, 0]] = 2
        self.y = self.y.type(torch.LongTensor)
        self.len = self.x.shape[0]
        
    # Getter
    def __getitem__(self,index):      
        return self.x[index], self.y[index]
    
    # Get Length
    def __len__(self):
        return self.len
Given the above code, generate some markdown instructions for it.
