如何削减bytearray?

I have a bytearray, and when I list the array, I get the following data: (b'v10 \ xc73 \ x9a & \ x9edv \ x19 \ xc3B \ xbf \ x95 \ xc8 \ xd8 \ x9dN \ x8f \ xe9 \ x90J \ xax> r1 \ x1d \ xa7 \ x1fU \ x90 \ XE2 (| p \ XF1 \ x02 \ xbdw \ XB8 \ xb9 \ xf3 \ x0e \ xb2n \ xc7 ',).

And I need to decrypt this data. But the decryption function only receives data, for example, b'v10 \ xc73 \ x9a & \ x9edv \ x19 \ xc3B \ xbf \ x95 \ xc8 \ xd8 \ x9dN \ x8f \ xe9 \ x90J \ xax> r1 \ x1d \ xa7 \ x1fU \ x90 \ xe2 (| p \ xf1 \ x02 \ xbdw \ xb8 \ xb9 \ xf3 \ x0e \ xb2n \ xc7' without () and ,

我能做什么?
