How to serialize Python dictionary to XML?

Use dicttoxml package to convert Python dictionary to xml representation.

To start, install dicttoxml package

pip3 install dicttoxml

Create a dictionary object

>>> D1={"name":"Ravi", "age":21, "marks":55}

Now import dicttoxml() function from dicttoxml package and use D1 as argument. The function returns encoded string as xml representation of dictionary

>>>fromdicttoxml import dicttoxml
>>>xml=dicttoxml(D1)

Obtain decode string by decode() function

The resulting string contains xml version of dictionary

>>>xml=xml.decode()
>>>xml
'<?xml version="1.0" encoding="UTF-8" ?><root><name type="str">Ravi</name><age type="int">21</age><marks type="int">55</marks></root>'

You can even store it in an xml file

>>>xmlfile=open("dict.xml","w")
>>>xmlfile.write(xml.decode())
>>>xmlfile.close()
