python Programming Glossary: particlesRandomizing (x,y,z) coordinates within a box http://stackoverflow.com/questions/12700211/randomizing-x-y-z-coordinates-within-a-box new to python and in my current assignment it looked at particles in 3D. The first part of the question asked to create a program.. to create a program that put identical non overlapping particles in a cubic lattice. So my code below just iterates through every.. but put them in a random fashion and limit the number of particles that I have. This is the code I had for the first part. import..
