Question

如何将整个循环压缩为一行。有什么办法吗？

var settings = {
    /* Appearance */
    headerTag: "h1",
    bodyTag: "div",
    contentContainerTag: "div",
    actionContainerTag: "div",
    stepsContainerTag: "div",
    cssClass: "wizard",
    stepsOrientation: $.fn.steps.stepsOrientation.horizontal,

    /* Templates */
    titleTemplate: '<span class="number">#index#.</span> #title#',
    loadingTemplate: '<span class="spinner"></span> #text#',

    /* Behaviour */
    autoFocus: false,
    enableAllSteps: true,
    enableKeyNavigation: true,
    enablePagination: true,
    suppressPaginationOnFocus: true,
    enableContentCache: true,
    enableCancelButton: false,
    enableFinishButton: true,
    preloadContent: false,
    showFinishButtonAlways: false,
    forceMoveForward: false,
    saveState: false,
    startIndex: 0,

    /* Transition Effects */
    transitionEffect: $.fn.steps.transitionEffect.none,
    transitionEffectSpeed: 200,

Answer 1

from itertools import product
aa = [x*y for x,y in product(args, args) if x != y]

Answer 2

以前的答案绝对没有错。双循环也可以，并且可能更容易理解。

[x * y for x in args for y in args if x != y]

列表理解中的条件嵌套循环
