问题 Is there a way to get the html string of a JavaScript Range Object in W3C compliant browsers?

问题 What does for (const auto &s : strs) mean? What is the function of colon : ? vector<string> &strs; for (const auto &s : strs){ // } 回答1: It's actually a C++11 feature called "range-based for-loops".

问题 I wrote the following for creating a range with negative floating point steps: def myRange(start, stop, step): s = start if step < 0: while s > stop: yield s s += step if step > 0: while s < stop: yield s s += step But the output of r = myRange(1,0,-0.1) looks rather strange >>> r = myRange(1,0,-0.1) >>> for n in r: print n ... 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 1.38777878078e-16 where does this last number come from? And why is it not 0? 回答1: Not all floating point numbers can be
