how I write the output into xml file in python?

[3lnyn0]

I have an automatically generated j son, I load it in the file (it is a list of dictionaries) and then I convert it to xml but how do I move the output to an "xml1.xml" file?

   import json
    from dicttoxml import dicttoxml

    with open("json_generat.json") as f:
       data = json.load(f)

    xml1 = dicttoxml(data)

I tried this but it doesn't fit me properly in xml file 
    f = open("xml1.xml", "w")
    f.write(xml1.decode())
    f.close()

Why not read the documentation of project dicttoxml? Based on this page, I would be tempted to write

from xml.dom.minidom import parseString
dom = parseString(xml1)
with open('xml1.xml', 'w') as ofh:
    print(dom.toprettyxml(), file=ofh)
