You can get specific break points by expanding the for loop into a
while loop, and this is perhaps why it has never been implemented with
for loops.
ctr_a=0
ctr_b=0
while ctr_a < len(generator_a):
this_el_a = generator_a[ctr_a]
while ctr_b < len(generator_b):
this_el_b = generator_b[ctr_ b]
if something_happen:
ctr_b = len(generator_b) ## break this loop
if something_else:
ctr_a = len(generator_a) ## break outer while loop
ctr_b += 1
ctr_a += 1
