Is there a way to use Natural Language Processing (NLP) to transform strings into integers?

I saw some examples of code to transform strings like, for example, "four" into an integer 4, but it was always quite manual. Do you have any more automatic way to do this using NLP?

One thing I noticed when I did the test below was that spacy recognizes both "four" and " 4 " as numbers, which is already a good start, but how do you use this to make the transformation from one type to the other? I don't understand much of language processing natural, so I do not know exactly what the name of the technique would be responsible for this.

nlp = spacy.load("pt")

doc = nlp("quatro vídeos")
for token in doc:
    print(token.text, token.pos_, token.dep_)
# retorna 
# quatro NUM nummod
# vídeos SYM ROOT

doc = nlp("4 vídeos")
for token in doc:
    print(token.text, token.pos_, token.dep_)
# retorna 
# 4 NUM nummod
# vídeos SYM ROOT

Thank you!
