The only difference between an inadvisable amount of stuff and a
reasonable amount of stuff is the amount. Don't we already have a
recommended column limit in PEP8?
for y in range(25) for x in range(80): doesn't seem unreasonable to me;
YMMV.
Or maybe you want to put it on multiple lines, but not consuming
indentation levels:
for x in seq1 if p1(x)\
for y in seq2 if p2(y)\
for z in seq3 if p3(z):
result.append(f(x, y, z))
