Not able to presever the words.

[Opperessor]

wanted to retain the format of few entities, unable to do.

text = "My phone number is +44(123)-1451-1231ext02 and my credit card is 1234-1235(2352), my policy number is 1234-12CAR-12 and my account number is 004421234-12"

def keyboard_aug():
    protected_entities = ["+44(123)-1451-1231ext02", "1234-1235(2352)", "1234-12CAR-12", "004421234-12"]
    aug = nac.KeyboardAug(stopwords=protected_entities)
    augmented_text = aug.augment(text)
    print("Original text:")
    print(text)
    print("Augmented text:")
    print(augmented_text)

output:
Original text:
My phone number is +44(123)-1451-1231ext02 and my credit card is 1234-1235(2352), my policy number is 1234-12CAR-12 and my account number is 004421234-12
