[Python] Modify specific subelement in xml with Python

I am starting to play around with Python but hit a wall in xml.

I am trying to edit a xml sub-element that maybe is stored in a not very conventional way, it has many numbers as text and more like a vector with all sub-elements named as 'double' although it is actually text...then I was expecting the xml to be.

This is a example of such file

<simulation>
<element1>'A'</element1>
<element2>
<subelement1>
<double>1</double>
<double>2</double>
<double>3</double>
<double>4</double>
<double>5</double>
</subelement1>
<subelement2>
<double>1</double>
<double>2</double>
<double>3</double>
<double>4</double>
<double>5</double>
</subelement2>
</element2>
</simulation>


What I want to do is to change all child nodes values from subelement1 for let's say: 10, 20, 30, 40, 50 having something like this in the end:

<simulation>
<element1>'A'</element1>
<element2>
<subelement1>
<double>10</double>
<double>20</double>
<double>30</double>
<double>40</double>
<double>50</double>
</subelement1>
<subelement2>
<double>1</double>
<double>2</double>
<double>3</double>
<double>4</double>
<double>5</double>
</subelement2>
</element2>
</simulation>


Can access all the nodes that I want to change with this:

import xml.etree.ElementTree as ET

for elem in root:
for subelem in elem.findall('.//element1/double'):
print(subelem.attrib)
print(subelem.text)


This shows the numbers I want to change (see below), but I could not find a way to actually change them to the ones I need.

{} 1 {} 2 {} 3 {} 4 {} 5


If I try to use it as a vector or something like this:

for elem in root:
for subelem in elem.findall('.//element1/double'):
subelem.text = [10,20,30,40,50]
print(subelem.text)


I end up not substituting, but adding information and the results are:

{} 1 [10,20,30,40,50]
{} 2 [10,20,30,40,50]
{} 3 [10,20,30,40,50]
{} 4 [10,20,30,40,50]
{} 5 [10,20,30,40,50]


What would be a way to make the changes? Thank you very much.
