How?? When you 't' within console the entire data frame is dumped but how are

but one can do the following
(x for x in 'apple').next() * 2
def foo():
(yield 2)
foo().next() * 3
(lambda x: 2)()*4
generator expr, yield expr, lambda expression
all require some modification (insertion of a .next or explicit () so
it's quite confusing..
expression seems to mean anything
Also you will note, one can do:
( 2 if 3 > 2 else 4 ) + 4
so the () is just for precedence but otherwise a Conditional Expression
works as expected by returning a value to be added to + 4.

A descriptor follows the descriptor protocol and implements the __get__

What is the return value of `exec`? Would that object be then used to
iterate the sequence in 'a'? I'm reading this:

1. What are the rules for using __del__ besides: 'don't use it'.
2. What happens when I SystemExit? __del__ and gc are not invoked when I

#!/usr/bin/env python3
fh = open('/etc/motd')
for line in fh.readlines():
print(fh.tell())
why doesn't this work as expected.. fh.readlines() should return a
