Why am I getting child index out of range error when I writing to XML file in python?

Question

I'm trying to write a name in the list of a dictionary to XML file but I'm getting IndexError as child index out of range. I'm new to XML file. Here is my code

import os
import xml.etree.ElementTree as ET
from xml.etree.ElementTree import Element, SubElement, Comment, tostring
from xml.dom import minidom
name = [{'vehicle': 'honda'}, {'vehicle': 'hyundai'}, {'vehicle': 'mercedes'}, {'vehicle': 'rangerover'}, {'vehicle': 'bentley'}, {'vehicle': 'toyota'}, {'vehicle': 'mecerati'}, {'vehicle': 'lamborgini'}]
l = [(0, 1), (0, 2), (0, 3), (0, 4), (0, 5), (0, 6), (0, 7), (1, 0), (1, 2)]
for step in range(10): 
            i,j = l[step]                      
            print(i,j)
            name1 = str(name[i]['vehicle'])
            root = Element('annotation')
            folder = SubElement(root, 'folder')
            folder.text="testing"
            filename=SubElement(root, 'filename')
            filename.text="1.jpg"
            path=SubElement(root, 'path')
            path.text="path"
            source=SubElement(root, 'source')           
            obj=SubElement(root, 'object')
            name=SubElement(obj,'name')
            name.text=str(name1)                                    
            tree = ET.ElementTree(root)
            tree.write(os.path.join('testing',str(step)+".xml"))  

When second iteration occurs with the same i value it throws the error.

    0 1
    0 2
---> 10             name1 = str(name[i]['vehicle'])


IndexError: child index out of range

can you help me to figure out what wrong I'm doing and a way to fix it? I found a similar question but it didn't fix my error Child index out of range, python element tree

Answer 1

In your for loop you do name=SubElement(obj,'name') , you are overwriting your original name list. Change that variable name to something else.
