Good day. It is necessary to parse xml and write to csv in python of the following form:

<Root> <SubRoot> <Level1>A</Level1> <Level2>B</Level2> <Level3>C</Level3> <Level4>D</Level4> </SubRoot> <SubRoot> <Level1>1</Level1> <Level2>2</Level2> <Level3>3</Level3> </SubRoot> </Root>

My code

 for subroot in root.findall('SubRoot'): level1 = subroot.find('Level1').text level2 = subroot.find('Level2').text level3 = subroot.find('Level3').text level4 = subroot.find('Level4').text print level1 print level2 print level3 print level4

The first SubRoot contains 4 levels, the second contains 3. The string l evel4 = subroot.find('Level4').text causes an error.
How to make it so that in the column header of the csv file there are 4 levels, the first row is full, and in the last cell of the second row it is empty.
An example in the image below. enter image description here

    To get an empty string if the element does not exist:

     level4 = subroot.findtext('Level4', default='')
