python sum frames from dictionary value

I have xml file that contains some kind of playlist and when I parse it I want to sum frames.

XML looks something like this:

<starttime>02-02-2021 01:30:52:154</starttime><frames>94</frames>  <starttime>02-02-2021 01:50:52:124</starttime><frames>96</frames>  <starttime>02-02-2021 02:50:52:124</starttime><frames>120</frames>  <starttime>02-02-2021 02:50:52:124</starttime><frames>180</frames>  

and I want to add to the dictionary and calculate frames in a specific hour so I have sliced date, min, sec... and leave only the hour, but in that case, I can't add multiple values to a key, because the last value overwrites all before. So I don't know how to sum all frames to that key.

the result should be

{'01':'200','02':'300'}

import os  import xml.etree.ElementTree as ET  from timecode import Timecode      file = '/home/Myxml.xml'  dom = ET.parse(file)    lista = dom.findall('PLAYLIST')      listXML = []  for l in lista:        type_md = l.find('type')  # COMMERCIAL      start_time = l.find('starttime')  # početak emitiranja      frames = l.find('frames')  # TC Duration        if type_md.text == 'COMMERCIAL':          listXML.append(start_time.text[11:-10])          listXML.append(frames.text)    listXML = list(zip(listXML[::2], listXML[1::2]))    clock_dict = {}  for x in listXML:      x_dict = list(zip(x[::2], x[1::2]))      clock_dict.update(x_dict)    print(clock_dict)      # print(clock_dict)
