And `'car'` is not an alphanumeric value? – Willem Van Onsem Jan 09 '18 at 10:15 — Willem Van Onsem, Jan 09 '18 at 10:15
Are they always at the end of a string? – splash58 Jan 09 '18 at 10:18 — splash58, Jan 09 '18 at 10:18
@Chai please have a look at the definition of alphanumeric. – RoadRunner Jan 09 '18 at 10:20 — RoadRunner, Jan 09 '18 at 10:20
@splash58 no they are not always at the end of the string – Chaitu Jan 09 '18 at 10:21 — Chaitu, Jan 09 '18 at 10:21

As mentioned by Willem Van Onsem, 'car' is also alphanumeric.

To get ka99ap9999 as output, first check every word is alphanumeric and then check it is not alphabetic and digit only.

d = ["his car number is ka99ap9999", "bike that met with accident is kl8ar888"]

for i in d:
    for x in i.split(' '):
        if x.isalnum() and not x.isalpha() and not x.isdigit():
            print x

Code :

python C:/Users/punddin/PycharmProjects/demo/demo.py
ka99ap9999
kl8ar888

That's nice, too. But you should adapt your description to also mention the "not digit only" check. – tobias_k Jan 09 '18 at 10:27

It seems like you are looking for words where any character isdigit and any character isalpha. Just put that in a list comprehension and you are done:

>>> d = ["his car number is ka99ap9999", "bike that met with accident is kl8ar888"]
>>> [w for s in d for w in s.split() if any(c.isalpha() for c in w) and any(c.isdigit() for c in w)]
['ka99ap9999', 'kl8ar888']

This way also works: `[w for w in " ".join(d).split() if any(c.isalpha() for c in w) and any(c.isdigit() for c in w)]` – RoadRunner Jan 09 '18 at 11:00
