Why is if statement not working in ElementTree parsing?

I'm trying to parse an xml file using ElementTree which looks like this:

</Event>


-<Event timestamp="2016-08-14T14:23:33.634" id="1713385925" 
version="1471181110290" last_modified="2016-08-14T14:25:11" y="11.0" 
x="89.7" outcome="0" team_id="148" player_id="51327" sec="8" min="23" 
period_id="1" type_id="4" event_id="205">

<Q id="733814222" qualifier_id="265"/>

<Q id="481660420" qualifier_id="286"/>

<Q id="813378778" qualifier_id="152"/>

<Q id="570443899" qualifier_id="56" value="Right"/>

<Q id="420312891" qualifier_id="233" value="248"/>

<Q id="1186861264" qualifier_id="13"/>

</Event>


-<Event timestamp="2016-08-14T14:23:33.634" id="1635888622" 
version="1471181110289" last_modified="2016-08-14T14:25:11" y="89.0" 
x="10.3" outcome="1" team_id="143" player_id="169007" sec="8" min="23" 
period_id="1" type_id="4" event_id="248">

<Q id="1871787686" qualifier_id="56" value="Back"/>

<Q id="176295814" qualifier_id="13"/>

<Q id="69346842" qualifier_id="233" value="205"/>

<Q id="1588029344" qualifier_id="265"/>

<Q id="559785299" qualifier_id="285"/>

<Q id="380723313" qualifier_id="152"/>

The code I'm using is simple and is working as expected. However, everything changes when I try to add an if condition to the code

import xml.etree.ElementTree as ET

root = ET.parse(r'C:\Users\ADMIN\Desktop\Abhishek\PSG - Copy\Sample.xml').getroot()

Games = root.getchildren()
for Game in Games:
    Events = Game.getchildren()
    for Event in Events:
        type_id = Event.attrib["type_id"]
        team_id = Event.attrib["team_id"]
        Qualifiers = Event.getchildren()
        for Qualifier in Qualifiers:
            id_ = Qualifier.attrib['id']
            if id_ == 142:
                print ("val")

Here's the error it's producing:

Warning (from warnings module):
  File "C:\Users\ADMIN\AppData\Local\Programs\Python\Python37\PSGPossessionSequences.py", line 9
    Games = root.getchildren()

I have tried removing the if statement and that works perfectly. However, I do need to set a condition to call all the id_s which are a certain value. I've tried using "142" as well as 142 but the problem persists. Why exactly is this happening?
