Silly Python riddle

Here's a silly Python riddle for you.

Today I opened up a Python 2.7 shell, and ran two commands in it.

>>> f = lambda: g(???)
>>> f() 

(Note that these are the only commands that I ran. You're not allowed to run any other commands before them.)

The riddle: What's the shortest thing you can put instead of ??? so my second command would not raise an exception?


Ram.

i didn't know lambdas can be used with a function call. 

actaully - i can't even use lambda: f() at all, even without your restrictions.

unless there's a jit compiler easter egg built in, like lambda g('if this string then return a 3d-maze with pictures of the developers')...

Re: Silly Python riddle

Of course you can put a function call inside a lambda:

>>> f = lambda: sum((1, 2, 3))
>>> f()
6

No easter eggs or JIT magic are involved in this riddle.

Re: Silly Python riddle

my trivial 13 char solution is
);g=lambda:(0
which gives 
f = lambda: g();g=lambda:(0)
but i'm sure this can be done with less...

Re: Silly Python riddle

Haha, I didn't consider that solution. And yes, it can be done with less characters than 13.

oops, i dislectically thought the g() is before the colon!
(still, i can't figure it out.)

Re: Silly Python riddle

I do not have Python 2.7, so I did the following on Python 2.6.6.
>>> f = lambda: g(); g = lambda:()

Re: Silly Python riddle

So you got it down to 12 characters, nice. But it can be made much shorter.

Re: Silly Python riddle

Very creative man! I definitely didn't think of that.

Still, the best solution I got runs at 7 characters.

Re: Silly Python riddle

Another attempt at golfing down the solution:
>>> f=lambda:g(0);g=(id)
>>> f()
10482512

The solution is '0);g=(id', 8 characters long.
If there is a built-in function whose name is 1-character long, then the
solution can be made to be 7 characters long.

Re: Silly Python riddle

Haha, I didn't think of all those creative answers when I asked this riddle! I'm sure happy that none of them (so far!) have reached 7 characters, which is the length of my solution.

Another attempt at golfing down the solution:
>>> f=lambda:g(0);g=(id)
>>> f()
10482512

The solution is '0);g=(id', 8 characters long.
If there is a built-in function whose name is 1-character long, then the
solution can be made to be 7 characters long.

Re: Silly Python riddle

f=lambda: g();g=set#)

(yuck. why am i participating in this riddle anyway..)


if i there's a class whose constructor returns a callable, it can be shorter.

Here's a silly Python riddle for you.

Today I opened up a Python 2.7 shell, and ran two commands in it.

>>> f = lambda: g(???)
>>> f() 

(Note that these are the only commands that I ran. You're not allowed to run any other commands before them.)

The riddle: What's the shortest thing you can put instead of ??? so my second command would not raise an exception?

I have a cheating solution that goes down to 3: """

It's cheating because your second line is not a command (and in fact, it makes 
the whole thing not yet a commnd):

>>> f = lambda: g(""")
... f()
... 

But still, at this point, no exception has been raised.

Yeah, that's a good cheat :)
