Thank you.

No, but now I do. What are you getting at?

Right, that's because on the first iteration of the while loop, Python doesn't yet know what the heck the room variable is. To fix this, just add this line of code to your program a second time, but this time add it before the while loop: room = raw_input("Enter a room number to move, or q)...

The best thing is if you run into her away from your house, then you can come up to her and say "Hey." and then wait for her to look at you and then say "I think maybe you live across the street from me" and then maybe she will recognize you and maybe not, and you can tell her that you...

Being able to understand a solution that someone else presents to you is not at all the same as being able to come up with solutions yourself. Think of the difference between a good soccer player and someone who can appreciate a good soccer game. That's something like the difference between...

Here are three different things you can try. You should try out a technique for at least a solid week before rejecting it definitively. 1. Use Autofocus. http://www.markforster.net/autofocus-system/ 2. Use the Pomodoro Technique. http://www.pomodorotechnique.com/ 3. Maybe you're...

My physics teacher says Halliday & Resnick might be the best undergraduate physics text ever. Can't say which edition he was referring to. There's also the Feynman Lectures.

I found this odd question in the back of the chapter supplement. I don't need to do it for homework and it probably won't be on the test but the fact that I don't know how to do the problem frustrates me. Here it is: * * * Use the fact that 21,375, 38,798, 34,162, 40,223, and 79,154 are all...

Sounds like something we're going to learn later in the quarter. What do you mean by "associated with mass"?

On the other hand, maybe you're right and I'm wrong because quarks also have charge...

Operational definitions can be good, but my teacher says when he first gave this question, he threw away all the quizzes in disgust because no one got even close. My guess is that since the operational definition is pretty obvious lots of folks used it and ended up getting their papers thrown...

Defining "charge" Hello folks, My physics teacher told the class that he was eventually going to give us a pop quiz with only one question: "In one sentence, without any math, what is charge?" I think I know the answer, but since it's going to count for an entire quiz grade, it'd be nice to...

al-mahed: But not if C, D, E, and F all have to be integers. In that case, 5 and 6 are unique.

Ok, I'll just tell you guys my answer. Hopefully you won't be angry with me. Stated in terms of integers C, D, E, and F, 5 and 6 are the only distinct integers such that C + D = 5 C * D = 6 E + F = 6 E * F = 5 where c = 2, d = 3, e = 5, and f = 1. In other words, 5 can be...

Guys, thanks for all the responses. The precondition can be stated in terms of all variables - no numbers necessary. (I guess I should have said this sooner, but it seemed like a bit of a hint.) That means *no* coefficients, only multiplication and addition of variables. But the answer can...
