Question

我希望以下代码运行已定义的函数，并将已定义函数的输出保存在指定的变量＆＃34; functionsOutput＆＃34;中。然后，我想用空格替换变量中的新行。

但我的下面的代码并没有这样做。我究竟做错了什么？将函数输出分配给变量是打印出输出。我不想要那个。我希望输出存储在变量中。

#!/usr/bin/python2.7
mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    for objects in mylist:
        objects = objects.replace('hello', "hi")
        print objects

functionsOutput = printWithoutNewlines()
functionsOutput.replace('\n', ' ')

Answer 1

以下代码应该提供您想要的输出，但是您想以这种方式完成它吗？

mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    for objects in mylist:
        objects = objects.replace('hello', "hi")
        print objects,
    print

printWithoutNewlines()

Answer 2

这里有几个错误：

您的功能不return。挥手告别之前做的最后一件事就是打印。
您正在为迭代器分配一个新值。这使得循环中的陈述已过时。

如果你纠正了这些错误，你甚至不必删除\n字符。

#!/usr/bin/python2.7
mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    output = ""
    for objects in mylist:
        output += objects.replace('hello', "hi")
    return output

functionsOutput = printWithoutNewlines()
print functionsOutput
>>> hiyouaresocool

Answer 3

您的功能是打印结果，我认为您想要的是返回值。我可以是这样的：

    (function(e) {
        var h = {
            blogURL: "",

        if (h.blogURL === "") {

                if ("media$thumbnail" in s[o]) {
                    u = s[o].media$thumbnail.url.replace(/\/s[0-9]+\-c/g, "/s" + h.ImageSize + "-c")
                } else {

            count++;

                var el = e( '<div></div>' ).html(l);
                e('li', el).sort(function (a, b) {
                   return e(b).attr('data-date') - e(a).attr('data-date');
                }).appendTo("ul", g);
            }
        };
        var b = function() {
            if (h.tagName === false) {
                i = "";
                e.ajax({

                    e("#prevx").click(function() {
                        e("#slides li:first").before(e("#slides li:last"));
                        return false

                        function j() {

        e(document).ready(b)
    })(jQuery)
};

function rotate() {
    $('#nextx').click();
};
document.write('')

事实上，它有点复杂，因为你需要添加空格等等。然后，您将不需要替换。
