Hi all,

I'm new to Python. I have this :

>>> import xml.etree.ElementTree as ET
>>> xml_to_parse1 = ET.parse('/tmp/xmlfile.xml')
>>> get_xml = xml_to_parse1.getroot()
>>> for x in get_xml.findall('physicaldisk'):
...     diskType =x.find('diskType').text
...     print(diskType)
...

I want add all these values (remove duplicate) to a LIST. How to do that in python?

If you want to get rid of duplicates, think "set". Just add() things to it and it will only store the unique elements.

>>> diskTypes = set()
>>> diskTypes.add("HardDisk")
>>> diskTypes.add("HardDisk")
>>> diskTypes.add("HardDisk")
>>> diskTypes.add("FlashDisk")
>>> diskTypes.add("FlashDisk")
>>> diskTypes.add("HardDisk")
>>> diskTypes
{'FlashDisk', 'HardDisk'}

Or a Counter dictionary. That gets you all the types and a count of how many of each type.

Something like this:

Output:
>>> from collections import Counter
>>> import xml.etree.ElementTree as ET
>>> xml_to_parse1 = ET.parse('/tmp/xmlfile.xml')
>>> get_xml = xml_to_parse1.getroot()
>>> disktypes = Counter([x.find('diskType') for x in get_xml.findall('physiccaldisk')])
>>> print(disktypes)

Something like this:

>>> get_xml = xml_to_parse1.getroot()
>>> disktypes = Counter([x.find('diskType') for x in get_xml.findall('physiccaldisk')])
>>> print(disktypes)

When I run this I got many "Elements" words as below:

x.find('diskType').text  # Missed the .text

I did say "Something like this"
