removing quotes from a list and keep type list

[buran]

start will be a str, so you can do something like

use map

>>> start = '192.168.1.99'
>>> start = list(map(int, start.split('.'))) # you need to convert the map object to list
>>> start
[192, 168, 1, 99]

or use list comprehension

>>> start = '192.168.1.99'
>>> start = [int(num) for num in start.split('.')]
>>> start
[192, 168, 1, 99]
