from nltk.stem import PorterStemmer

porter = PorterStemmer()
porter.stem("mobile")

You might be looking for lemmatization and not stemming. Check out https://www.guru99.com/stemming-lemmatization-python-nltk.html.

Stemming means the reduction to the root/base of the word. Lemmatization means the reduction to the non-flectional base form (e.g. infinitive for verbs).

The root of "mobile" is "mobil" because of words like "mobility". The unchanged root/base does in this case not include the e.
