It doesn't matter as none of this is valid Python. In Python you have to
write

array[x1] = False
array[x2] = False

Uh...not so much...

 >>> a = [1,2,3,4,5]
 >>> x1, x2 = 1, 3
 >>> a[x1] = a[x2] = False
 >>> a
 [1, False, 3, False, 5]

Works for me.

To the OP, I think rather than cluttering my code, I'd just create a loop

  for i in [x1,x2,x3,x4,...x1024]:
    a[i] = False

From Diez's disassembly of it (as an aside, nifty little intro to dis.dis()...thanks, Diez!), it looks like it boils down to "is DUP_TOP faster than LOAD_CONST" because the rest of the operations. At this point, it's pretty nitty-gritty.

Unless the code is in an inner loop somewhere, the simple loop should be more than fast enough. Without knowing the source of the [x1,...] index variables, it's hard to tell if there's a more optimal way to do this.
