import capstone

print(capstone.__version__)
md = capstone.Cs( capstone.CS_ARCH_X86, capstone.CS_MODE_32 )
insn = next(md.disasm(b'\xf2\xa4', 0, 1)); print('%s %s %s' % (insn.bytes.hex(), insn.mnemonic, insn.op_str))
insn = next(md.disasm(b'\xf2\xa5', 0, 1)); print('%s %s %s' % (insn.bytes.hex(), insn.mnemonic, insn.op_str))

5.0.3

f2a4 repne movsb byte ptr es:[edi], byte ptr [esi]

f2a5 repne movsd dword ptr es:[edi], dword ptr [esi]
