It's unfortunate that loop variables leak from list comprehensions (they
don't leak in genexps). It's by design in for loops though. Consider:
for i in range(10):
if i*i == 9:
break
print i
In this silly example, the loop index is the useful value of the
computation. You could assign to a different variable, though that would be
slightly ugly:
for i in range(10:
j = i
if j*j == 9:
break
print j
