Python - For every value in text file? -

with code writing, have split text file using commas, , each value in there, want make integer. have tried splitting text file , turning integer not work. there way of saying values in file, thing? also, amount of values isn't concrete, depends on user of programme (it 'shopping list' programme. current code:

totalcosts=open("totalcosts.txt","r") prices=totalcosts.read()  print(prices) prices.strip().split(",") intprices=int(newprices) print(len(intprices))  if len(intprices)==1:     print("your total cost is: "+intprices +" pounds") elif len(intprices)>1:     finaltotal = sum([int(num) num in intprices.split(",")])     print("your total cost is: "+ finaltotal +" pounds") 

prices file values contained in, i've stripped of whitespace , split it. need continue on from. thank xx

results = [int(i) in results] 

python 3 can do:

results = list(map(int, results))
