| | Re: For loop a simpler way, without having to convert i to a string could be: [code=python] name='harry' name2='verderchi' nt=8 #number of times to print for i in range(1,nt+1): print '#%s:%s %s'%(i, name, name2) [/code] the %s is a placeholder for the variables inside the brackets.  |
| | Hi, I've got some c++ code(which i don't have much experience in). I'm trying to write the same code again in python but i'm not having much luck. The c++ code creates an array of x,y co-ordinates: [code=c++] for (double ix = 0; ix < nlat; ix++) { for (double … |

| | How are you wanting to arrange your x and y values? What you have done is correct if you want to create a list of x's and a list of y's whos values are 1 greater than the corresponding x. Ah I think you want to do it in M-code. … |
| | Hi. I've read the documentation but I can't quite work out how i create an object and give it attributes. I'm trying to create a disk object that has attributes disk.x and disk.y which i can then identify with a line, [code=python] disk.id = (x,y) [/code] |

| | Is there an easy way of doing this? for example my list is: [code=python] nlat=10 mylist = [] for x in range(0,nlat): for y in range(0,nlat): disk=sphere(pos=(x*s,y*s), radius = r, color=(0,1,9)) mylist.append(disk) [/code] or is it impossible to place objects, such as a sphere from vpython into a numpy array?, … |
| | Hi, I'm making a program in VPython to simulate the motion of particles. It's fairly simple in theory but I'm having some problems with my lists of particles. What I'm trying to do is make sure that the particles do not overlap, and regenerate a position if they do overlap. …  |
| | If you are using windows, I would recommend notepad++ You can set the language so it will highlight your code for you. I believe you can also set it to run the script immediately from the editor without too many headaches: [url]http://users.cse.ucdavis.edu/~cmg/courses/nlp/Software/Windows/npp.html[/url] |
