尝试将ElementTree写入XML fi时，“TypeError:write（）参数必须是str，而不是字节”

Question

我试图用^{}方法将一些XML作为字节字符串（即Zillow API的响应）写入XML文件。下面是我要做的一个例子：

from xml.etree import ElementTree

root = ElementTree.fromstring(content)
tree = ElementTree.ElementTree(root)

with open(f"comparables.xml", 'w+') as fp:
    tree.write(fp)

但是，如果我运行这个（在iPython中），我得到一个TypeError：

^{pr2}$

我传递的不是文档中指定的“文件对象已打开以供写入”吗？在

我尝试过遵循ElementTree TypeError "write() argument must be str, not bytes" in Python3中的解决方案，但是tostring方法似乎不再包含在xml.etree模块中。在

Answer 1

结果是，tree.write()的参数应该是您要创建的文件的名称：

tree.write("comparables.xml")

在当前目录中创建comparables.xml。在
