问题 I haven't used Matplotlib much. Based on someone's advice, I'm trying to write some plotting codes using object-oriented paradigms as much as possible---and therefore trying to use pure Matplotlib (i.e. not relying on pyplot) to generate some simple figures. A stripped-down version of my code looks like this: import matplotlib as mpl time = [0,1,2,3,4] cell = [1,2,1,2,1] sample = [3,2,3,4,4] (figHt, figWd) = (5, 8) # in lBorderWidth = bBorderWidth = rBorderWidth = tBorderWidth = 0.1 lbwh =

问题 I've installed a virtualenv with pyenv using Python v2.7.12. Inside this virtualenv, I installed matplotlib v1.5.1 via: pip install matplotlib with no issues.

问题 What do you think.. are clean URLs a backend or frontend 'discipline' 回答1: If we're talking url's being 'clean' from an end user experience then I'm going to break the mould a bit and say that url's in general are not intuitive and they never will be, they are intended to be machine readable.
