They would understand the underlying concept. But would somebody who
is not a Python programmer intuitively understand the difference
between this:
[x + 3 for x in xs if x % 2 == 1]
and this:
{x + 3 for x in xs if x % 2 == 1}
and this:
(x + 3 for x in xs if x % 2 == 1)
Somebody with rudimentary Python knowledge might even reason that
since the first two create a list and a set respectively, the third
must therefore create a tuple, which is wrong.
None of this should be taken as an argument against using generator expressions.
