Find substrings in string using python

Question

I have data

vk.com/idefiks
vk.com/id211452033
vk.com/id211452033
vk.com/id165402000
vk.com/id_lizalizaelizaveta

I need to get all url, where are numbers after id. If I use

if '/id' in url:

it returns all strings. How can I return only id with number?

you can use re module. for example:

import re
s = """
vk.com/idefiks
vk.com/id211452033
vk.com/id211452033
vk.com/id165402000
vk.com/id_lizalizaelizaveta
"""
p = re.compile('/id\d+')
print p.findall(s)

The output will be:

['/id211452033', '/id211452033', '/id165402000']

PS: if want to remove / in the result, just update regular expression to /(id\d+). that is because, findall just returns the captured groups

Simplest solution :

x = "vk.com/idefiks"
x[6:]

This will give : /idefiks

If you want to omit the / use x[7:].

You may do it using re too, but that's not required for this case.

if '/id' in url:
    result = url.split('/id')[-1]
