Personally, I find that harder to read.

How about adding a comment? it maybe more readable.
#swap two imaginary numbers with real part and imaginary part (data[ii],data[ii+1]) <->(data[jj],data[jj+1]) .

Yes, it maybe more longer making it seems harder read. How about if we first look at data[ii] to the left of “=”, then look at data[jj] to the right of “=”, then loop the operation? Sometimes, I find the original code have more statements making me a little scared and confused to read the code.

It is indeed harder to read and we should avoid changing benchmarks unless necessary, BTW the bytecode will now use unpack sequence rather than store name so will have an effect on its specialization.

while k <= j:
j -= k
k >>= 1
