How to get integer values from a string in Python?
Question: 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]
