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 1

>>> 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]

r = "456results string789" s = ''.join(x for x in r if x.isdigit()) print int(s) 456789
