Assign properties to a child table

hello, i have a doctype named ‘part’ with a table on it named ‘provider_part’, in a python y scripted a function that call a api and assign the prices to a variable named a1.

i customize a button who runs the function on ‘part’

on ‘provider_part’ i have a custom fields named in function of the quantity of the product where i want to save the prices that returns me the api.

the problem is: when i push the button, he runs the code on python, but that didn’t set the prices where i want

there are some pictures and code:

@frappe.whitelist()
def octopart_api(part,name):
	objPart = frappe.get_doc(part,name)
	queries = [{'mpn':objPart.mpn}]
	queries = json.dumps(queries)
	octoKey = {'apikey':'8c941dcc','queries':queries}

	obj = requests.get("https://octopart.com/api/v3/parts/match",params = octoKey)
	print(obj.url)
	obj = obj.json()

	
	for offer in objPart.part_provider:
		a1 = []

		for offerOct in obj["results"][0]["items"][0]["offers"]:
			if offerOct["seller"]["name"] == offer.provider:
				if offerOct["prices"].has_key("USD"):
					aux=offerOct["prices"]["USD"]
					a1.append(aux)	
				
		if len(a1) == 0:
			print ('a1 = error')
		else:
			for uprice in a1[0]:
				if uprice[0] <= 10000:
					tablaplace = getattr(offer,'10000')
					tablaplace = 
					
				elif uprice[0] <= 5000:
					tablaplace = getattr(offer,'5000')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 1000:
					tablaplace = getattr(offer,'1000')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 500:
					tablaplace = getattr(offer,'500')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 100:
					tablaplace = getattr(offer,'100')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 50:
					tablaplace = getattr(offer,'50')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 25:
					tablaplace = getattr(offer,'25')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 10:
					tablaplace = getattr(offer,'10')
					tablaplace = float(uprice[1])

				elif uprice[0] <= 1:
					tablaplace = getattr(offer,'1')
					tablaplace = float(uprice[1])

Not sure what you are trying to do here. Can you specify the line number you are trying to debug? Also try using print to debug such cases.
