How to update Bitrix24 list item in Python3 from AWS Lambda

The main problem is that when updating a list item, we need to fill not only field we need to update but all the fields. Therefore, before the update, we must first request all the fields of the element by ID, reformat them into another array, and only then update.

	import json
	from botocore.vendored import requests
	def lambda_handler(event, context):
	ib_id=event['ib_id']
	el_id=event['id']
	data={
	'IBLOCK_TYPE_ID': 'lists',
	'IBLOCK_ID': ib_id,
	'ELEMENT_ID': el_id,
	}
	response = requests.get('https://bedrosova.bitrix24.ru/rest/1/****************/lists.element.get',data)
	list_data=response.json()
	fields={
	"NAME":list_data['result'][0]['NAME']
	}
	for k in list_data['result'][0]:
	if(k.startswith('PROPERTY')):
	for k2 in list_data['result'][0][k]:
	fields[k]=list_data['result'][0][k][k2]
	fields['PROPERTY_447']='222'
	data={
	'IBLOCK_TYPE_ID': 'lists',
	'IBLOCK_ID': ib_id,
	'ELEMENT_ID': el_id,
	'FIELDS':fields
	}
	response = requests.get('https://bedrosova.bitrix24.ru/rest/1/************/lists.element.update',http_build_query(data))
	result=response.json()
	#print(result)
	return {
	'statusCode': 200,
	'body': json.dumps('Hello from Lambda!')
	}
