You guess wrong. Python also has generator expressions, which are written
using round brackets instead of square.
In short, the syntax:
it = (expr for x in seq if cond)
is equivalent to:
def generator():
for x in seq:
if cond:
yield expr
it = generator()
except it doesn't create the generator function first.
