带有 for 循环的嵌套字符串列表

Question

我有以下两个嵌套列表List 1: [["Bob", "Davon", "Alex"],["Dylan","Rose", "Hard"]] List 2: [["Red", "Black"] , ["Blue", "Green"], ["Yellow", "Pink"]]并希望一起显示嵌套中每个列表的第一个单词，第二个等等。这样结果将是：['Bob and Dylan', 'Davon and Rose', 'Alex and Hard'] --> for the first list['Red and Blue and Yellow, 'Black and Green and Pink'] --> for the second list所以我可以用下面的代码得到第一个结果name_list = [["Bob", "Davon", "Alex"],["Dylan","Rose", "Hard"]] def addition(name_list):        new_list = []    for i in range(len(name_list)):        for j in range(len(name_list[i])):            new_list.append(name_list[i][j] + " and " + name_list[i+1][j])        return new_list       addition (name_list)但第二个清单：[["Red", "Black"] , ["Blue", "Green"], ["Yellow", "Pink"]]没有提供正确的结果。

Answer 1

names_list = ["{} and {}".format(*t) for t in zip(*name_list)]

colors_list = ["{} and {}".format(*t) for t in zip(*color_list)]

这可能不适用于python2.7，无论如何你最好升级到python3，因为python2即将结束

Answer 2

[' and '.join(x) for x in zip(*name_list)]

[' and '.join(x) for x in zip(*color_list)]

str.join()将在任何大小的列表上工作，将字符串放置在每个项目之间。
