从Python中的字符串中删除子字符串？

Question

I´m currently facing the problem that I have a string (deeplink) of which I want to extract one certain substring:

   <deeplink>https://www.jsox.de/tokyo-l200/tokio-skytree-ticket-fuer-einlass-ohne-anstehen-t107728/?partner_id=M1</deeplink>

   <deeplink>https://www.jsox.de/tokyo-l201/ganztaegige-bustour-zum-fuji-ab-tokio-t65554/?partner_id=M1</deeplink>

I expect to get extract the following information from the strings above:

t107728
t65554

How can I only extract for example the substring t107728 from the the first string above? I tried it with the split and sub function but it does not work out

Can you guys help me out? Any feedback is appreciated

Answer 1

You can use re :

import re
s = ['<deeplink>https://www.jsox.de/tokyo-l200/tokio-skytree-ticket-fuer-einlass-ohne-anstehen-t107728/?partner_id=M1</deeplink>', '<deeplink>https://www.jsox.de/tokyo-l201/ganztaegige-bustour-zum-fuji-ab-tokio-t65554/?partner_id=M1</deeplink>']
new_s = [re.findall('[a-zA-Z0-9]+(?=/\?)', i)[0] for i in s]

Output:

['t107728', 't65554']

Answer 2

You can try this one, using the split function:

strings = ["<deeplink>https://www.jsox.de/tokyo-l200/tokio-skytree-ticket-fuer-einlass-ohne-anstehen-t107728/?partner_id=M1</deeplink>", "<deeplink>https://www.jsox.de/tokyo-l201/ganztaegige-bustour-zum-fuji-ab-tokio-t65554/?partner_id=M1</deeplink>"]

results = [elem.split("/?")[0].split("-")[-1] for elem in strings]

print(results)

Output:

['t107728', 't65554']
