How to get integer values from a string in Python?

Suppose I had a string

string1 = "498results should get"


Now I need to get only integer values from the string like
498
. Here I don't want to use
list slicing
because the integer values may increase like these examples:

string2 = "49867results should get"
string3 = "497543results should get"


So I want to get only integer values out from the string exactly in the same order. I mean like
498,49867,497543
from
string1,string2,string3
respectively.

Can anyone let me know how to do this in a one or two lines?

Answer
>>> import re
>>> string1 = "498results should get"
>>> int(re.search(r'\d+', string1).group())
498

If there are multiple integers in the string:

>>> map(int, re.findall(r'\d+', string1))
[498]
