How can I convert instance of object to curve ID

I have made a copy of the edge of the surface and place them in grid via for loop. The new I have print out the copied edge and found that they have no ID but they are the instance.

Something like this:

<__main__.drawBrick instance at 0x0000000000000152>
<__main__.drawBrick instance at 0x0000000000000153>
<__main__.drawBrick instance at 0x0000000000000154>
<__main__.drawBrick instance at 0x0000000000000155>
<__main__.drawBrick instance at 0x0000000000000156>

However the normal curve id would be like this:

e75cc76b-f698-4fce-a3f1-5450de260fcd

I would like to crete id for each instance, what should I do in Python?

Thank you
