Python练习

Question

这段代码用于code的Madlibs练习，它应该从用户那里获取一些输入，然后打印一个非常有趣的输出。

有一个故事已经提供在网站上，我没有修改它。

当我运行这个脚本时，我会得到以下错误：

回溯(最近一次呼叫most)： 文件"Madlibs.py"，第30行 打印：“今天早上我醒来，感觉到%s，因为_s最终会超过大%s，而在%s的另一边，有许多%ss抗议将%s保存在商店中。人群开始向%s的方向移动，这使得所有的%ss都变得非常_。%s试图进入下水道，发现%s鼠。在需要帮助的情况下，%s迅速出现并保存了%s，方法是飞到%s并将%s. %s扔到%s. s的水坑中，然后在_年睡着并醒来，在一个%ss统治世界的世界中醒来。“%s (a1，name，v1，a2，n1，n2，动物，食品，v2，n3，水果，a3，name，v3，Number，name，超级英雄，超级英雄，名字，国家，名称，甜点，名称，年份，n4) TypeError:不是所有在字符串格式化过程中转换的参数。

输出也打印“打印”！

请注意，在故事中，有一些地方我们有'%ss‘而不是'%s’。Codeacademy希望用户使用'%ss‘(我想是的)

此外，我尝试用'%s‘替换’'%ss‘’-我得到了相同的错误。

将所有‘’%1！‘’和‘%1！’‘替换为'%r’和‘’%1！‘’，并得到相同的错误。

在整个过程中将'%rr‘替换为'%r’，并得到相同的错误。

还有一点我必须提到，代码要求用户提供所有的raw_input是正确的，但是无法替换故事中的内容，并且只使用%s或%r与错误消息一起打印故事。

有人能帮我一下吗。我的代码在我看来很好，我不明白错误信息是怎么回事。

下面是代码(请与我一起重复这篇文章)

# This is a story for Mad Libs !!!

print "Mad Lib is staritng now."

Answer 1

这个链接提供了一个解决方案。往下读。似乎您需要用%s替换所有__。

所以，例如，而不是

print "This morning I woke up and felt %s because _ was going to finally %s over the big _ %s. On the other side of the %s were many %ss protesting to keep %s in stores. The crowd began to _ to the rythym of the %s, which made all of the %ss very _. %s tried to _ into the sewers and found %s rats. Needing help, %s quickly called %s. %s appeared and saved %s by flying to %s and dropping _ into a puddle of %s. %s then fell asleep and woke up in the year _, in a world where %ss ruled the world." %(a1, name, v1, a2, n1, n2, Animal, Food, v2, n3, Fruit, a3, name, v3, Number, name, Superhero, Superhero, name, Country, name, Dessert, name, Year, n4)

它应该是

print "This morning I woke up and felt %s because %s was going to finally %s over the big %s %s. On the other side of the %s were many %s protesting to keep %s in stores. The crowd began to %s to the rythym of the %s, which made all of the %s very %s. %s tried to %s into the sewers and found %s rats. Needing help, %s quickly called %s. %s appeared and saved %s by flying to %s and dropping %s into a puddle of %s. %s then fell asleep and woke up in the year %s, in a world where %s ruled the world." %(a1, name, v1, a2, n1, n2, Animal, Food, v2, n3, Fruit, a3, name, v3, Number, name, Superhero, Superhero, name, Country, name, Dessert, name, Year, n4)

Answer 2

元组中还有许多参数( (a1，name.)参数)，而不是字符串中有%s。确保每个参数与字符串格式的精确1 %s匹配才能工作。
