Python，html和写入文本文件

Question

我正在创建一个html字符串并将其写入一个.html文件。我用json和xml从网站上提取数据。这将拉动文本和链接，并将它们放入三重引号字符串中。还有更多的这个HTML字符串，但这很多将显示问题。我有一个函数获取新闻字符串并将该字符串写入.html文件。我知道所有的数据插入的作品，因为在我发送字符串写入文件函数之前，我已经打印到屏幕上并将其复制到文本文件并显示在浏览器上，并且它正确显示所有正确的数据。 python写入文件时发生问题。我得到一个“必须是字符串错误”。

当只有数据是文本时它才写入文件，但一旦它开始成为urls它将无法写入。那么，它不会写每一次，但一旦足够。

我有一个理论。一些网址包含转义字符或其他一些（未编程时间过长）。或者，也许我插入的数据在插入到html字符串之前需要使用三重引号。我不确定这甚至是可能的。

我尝试过使用这个插入数据：新闻％（数据，数据，数据），但它不能解决问题。

Answer 1

我不能肯定地说，没有看到输入数据，但很可能是因为他们中的一些数字（int，float）或可能unicode（这将产生UnicodeEncodeError）。

做将是包装在str(…)或unicode(…)所有变量的最简单的事情，但如果是我写这个代码，我会安装Jinja2并做到这一点使用一个“真正的” HTML模板语言（这将有环和东西，这将使HTML模板更容易阅读）。
