Answer 1

you can use regex:

import re
just = 'Standard Price:20000'
price = re.findall("\d+", just)[0]

OR

price = just.split(":")[1]

Answer 2

Considering the same code from the question:

>>> just='Standard Price:20000'
>>> price = int(filter(str.isdigit, just))
>>> price
20000
>>> type(price)
<type 'int'>
