Horrible programming student here. I have to make an 8x8 checkerboard using python & this graphics module a professor made. As of right now this is what I have from cs1graphics import * paper = Canvas(400,400) blackSquare = Square(50, Point(75,25)) blackSquare.setFillColor('black') paper.add(blackSquare) I know I need to use the modulus operator (%) within a loop to make it so that it inserts a black square in every even square, but I can't think of how to do this shit to save my life right now. After I put down the squares in a loop I have to actually put checkers on the image, but I think after I actually understand how to loop in the black squares I'll understand how to do that. Help?

I'm having problems with this. Image is related. I've worked out the following: Boundaries: + and - 400 picometers Wavelength: 1950 picometers. With this information, how can I answer the following questions? 1) What is the approximate kinetic energy of the electron inside the well? Kinetic energy = _____eV. 2) Now consider an infinite square well potential of the same width L. When the electron is in the ground state of this infinite well, is its kinetic energy higher or lower than its kinetic energy in the ground state of the finite well? Is it higher or lower? 3) If the electron were in the ground state of an infinite square well of the same width L, what would be its kinetic energy? Its kinetic energy = _____eV. I would really appreciate if anyone can help or provide insight into this.

Hi /sci/, I'm a beginner in Python. I need to make a program that counts the number of alliterations in a sequence of words. For example, ["frog", "friend", "cat", "apple", "asthma"] would count 2. How do I do this? What functions should I be looking at?

Is chemical engineering a very stressful job? I'm pursuing it, but I have generalized anxiety disorder and can not handle high stress levels at all. Should I switch to comp sci? I've been considering that due to low stress levels, but chem E has better wages, better hiring outlook, and is more interesting to me. Difficulty understanding the material is a non-issue for me, the problem is with large workloads and deadlines.

Give me a good documentary about space that's not full of bullshit. How the Universe works, The Universe, and especially Through the Wormhole are just full of it. I need something serious, without the layman terms and non stop action music. Also, without the stupid comparisons.. Like in the first episode of through the wormhole when they compare the universe to chocolate. That really gave me cancer.

Hi /sci/ I have to prepare a lab assignment about recrystallization and the prof gave us a few questions to answer. I'm not asking you guys to do my homework, but there's one question I just can't get my head around. Please help. (Also, sorry if some of the terms are incorrect, I have to translate this shit.) "Suppose that after a reaction you have a mixture of 500mg product A and 10mg contamination B. Both substances have the ssame solubility in water, 0.5g/l at 0°C and 18g/l at 100°C. Can you separate pure A by doing one recrystallization in water? If yes, how many milligrams of pure A will you have? Give detailed calculations. At first sight I would say that it's not possible, but I think it should be because they ask for detailed calculations. Please help? pic unrelated

So, i've been thinking, if you could construct a ray gun or some kind of thing that could remove all bonds between (like hydrogen bonds) molecules and inside of molecules (like van der waals or covalent bonds) so that all that would remain would be the basic elements themselves. What would happen if you used it on like a human? Would it just fall apart into a super-dense small pile of "dust"? In that case, how would the color change`? And could you even place the pile on something?, or would it just fall trough all matter, seeing how there are just a bunch of loose atoms?
