Comment (by jdemeyer):
Two details:
1. `an set` should be `a set`
2. Why this change? I find the old version more readable.
{{{
#!diff
- good_sum = (nu >= p.min_sum and nu <= p.max_sum)
- good_length = (l >= p.min_length and l <= p.max_length)
- no_trailing_zeros = (l <= max(p.min_length,0) or mu[-1] != 0)
- return good_sum and good_length and no_trailing_zeros
+ return (nu >= p.min_sum and nu <= p.max_sum # Good sum
+ and l >= p.min_length and l <= p.max_length # Good
length
+ and (l <= max(p.min_length,0) or mu[-1] != 0)) # No
trailing zeros
}}}
If this is for performance reasons, you can instead `cdef bint` the
variables `good_sum`, `good_length` and `no_trailing_zeros`.
