You can cast them into integers using int().

For example, given a file full of numbers "file.num"

values = []
with open("file.num") as f:
  for line in f:
     for value in line.split():
        values.append(int(value))

print(values)

Of course this is not production quality since it doesn't handle files that have badly formatted integers. For that, you probably want a try block around the cast to int on line 5
