ElementTree TypeError "write() argument must be str, not bytes" in Python3
Specify encoding of string while writing the xml file.
Like decode(UTF-8)
with write()
.
Example: file.write(etree.tostring(doc).decode(UTF-8))
As it turns out, tostring
, despite its name, really does return an object whose type is bytes
.
Stranger things have happened. Anyway, here's the proof:
>>> from xml.etree.ElementTree import ElementTree, tostring
>>> import xml.etree.ElementTree as ET
>>> element = ET.fromstring("<a></a>")
>>> type(tostring(element))
<class 'bytes'>
Silly, isn't it?
Fortunately you can do this:
>>> type(tostring(element, encoding="unicode"))
<class 'str'>
Yes, we all thought the ridiculousness of bytes and that ancient, forty-plus-year-old-and-obsolete encoding called ascii
was dead.
And don't get me started on the fact that they call "unicode"
an encoding!!!!!!!!!!!
The output file should be in binary mode.
f = open('sample.svg', 'wb')
Try:
f.write(et.tostring(doc).decode(encoding))
Example:
f.write(et.tostring(doc).decode("utf-8"))
