ElementTree writes exactly what you tell it to. In XML, whitespace is
significant. If you want newlines and/or indentation to make it pretty-looking,
then you need to add those to your elements.

Fredrik provides an example function for doing this:

This is not always true. Let me quote an XML tutorial (by Oracle):


"What is XML Whitespace?
XML considers four characters to be whitespace: the carriage return
(\r or ch(13)), the linefeed (\n or ch(10)), the tab(\t), and the
spacebar (' '). In XML documents, there are two types of whitespace:

Significant whitespace is part of the document content and should be preserved.
Insignificant whitespace is used when editing XML documents for
readability. These whitespaces are typically not intended for
inclusion in the delivery of the document.

Usually without DTD or XML schema definition, all whitespaces are
significant whitespaces and should be preserved. However, with DTD or
XML schema definitions, only the whitespaces in the content are
significant as follows:
