reading the documentation may help:
/.../ the elements of the new list are those that would be produced
by considering each of the for or if clauses a block, nesting from left
to right, and evaluating the expression to produce a list element each
time the innermost block is reached.
the clauses nest from left to right, not from right to left, so "[x for
x in y for y in beta]" is equivalent to
out = []
for x in y:
for y in beta:
out.append(x)
