问题 I have been trying to learn how to code for Maya for a while. And here I am making a rock generator using reduce face, quad-mesh, smooth in a loop. Now I would like to make an input so user can specify how many rock they want to make. Like if you input 5, it would make 5 rocks. However I am currently stuck with the naming, like if I created the polyPlatonicSolid with rock#, the loop got confused and said something like rock# is invalid , so I am just looking for a simple solution for that.

问题 I have the following list of lists (): [[u' why not giving me service'], [u' option to'], [u' removing an'], [u' verify name and '], [u' my credit card'], [u' credit card'], [u' theres something on my visa']] and I have the following questions: First, what are these u' appearing in front of every of my sublists? Second, how can I plit my sublists into separate words, i.e. have something like this: [[why, not, giving, me, service], [option, to], [removing, an], [verify, name, and], [my, credit

Since there is also a function for full screen in the code, I wanted to create a title screen that: Displayed the animation Turned into full screen when the key was activated Continued the animation at the point it was before activating full screen In order to do this, I resorted to threading . However, this is the first time I tried to do any multi-threading, and I don´t know what did

问题 I'm trying to replicate (and if possible improve on) Python 2.x's sorting behaviour in 3.x, so that mutually orderable types like int , float etc. are sorted as expected, and mutually unorderable types are grouped within the output. Here's an example of what I'm talking about: >>> sorted([0, 'one', 2.3, 'four', -5]) # Python 2.x [-5, 0, 2.3, 'four', 'one'] >>> sorted([0, 'one', 2.3, 'four', -5]) # Python 3.x Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError:

问题 How can I save a 3d pyplot image so that I can still rotate it in my pdf viewer? I know pdfs can be saved so that the 3d image can be rotated (I've had files like this before) - how can I accomplish this using pyplot? The motivation for this question is that I want to share images which others can rotate - it is not sufficient for me to rotate the image in the python viewer, taking 2d snapshots. Here is my example code. I cannot rotate the image in the pdf which this generates. import numpy
