或Python 3变量中的语句

Question

我正在尝试创建一个简单的python程序，在一个单词的开头检测一个constanant并将其移动到最后（如piglatin）。我可以制作像

这样的变量吗？

conts = "b" or "c"

然后if / else检测单词是以b还是c开头。这可能吗？

你无法做到这一点，但一个简单的选择是使用conts = {'a', 'b'} my_string = 'apples' if my_string[0] in conts: print(my_string[1:] + my_string[0]) else: print(my_string) 运算符。

    var id = "";

                token = response;

    var createCollectionCms = function(token, id){

            cms.login()
                .then(zebedee.createCollection(token))
                .then(zebedee.deleteCollection(token,id));
            setTimeout(resolve, 6000);
        });
    }
    createCollectionCms();
