Python: How to categorize the request in different categories for example in 3 categories based on any 3 ex. aa, bb, cc (any):, using KMeans or any other classification technique, I need just categories. help will be highly appreciated. thanks in advance! 
import random
class Req():
def __init__(self,reqNum,node_num):
self.reqNum = reqNum
self.location = random.randint(0,node_num//10)
self.firewall_demand = random.randint(300,600)
self.storage_demand = random.randint(100,300)
self.bandwidth_demand = random.randint(200,500)
self.fw_dm = random.randint(200,400)
self.st_dm = random.randint(150,350)
self.bw_dm = random.randint(250,550)
def createSetOfRequest(req_num, node_num):
sr = []
for i in range(0, req_num):
sr.append(Req(i, node_num))
return sr
# (i have to categorise in 3 category, scenario will be like that you can change accordingly, this is just for example)
ns = createSetOfRequest(20,200)
for i in range(0,20):
print(sr[i].reqNum,sr[i].firewall_demand ,sr[i].firewall_demand ,sr[i].bandwidth_demand)
