它称为“自然排序顺序”，来自http://www.codinghorror.com/blog/2007/12/sorting-for-humans-
natural-sort-order.html
尝试这个：
import redef sort_nicely( l ): """ Sort the given list in the way that humans expect. """ convert = lambda text: int(text) if text.isdigit() else text alphanum_key = lambda key: [ convert(c) for c in re.split('([0-9]+)', key) ] l.sort( key=alphanum_key )
