Example:
I have a sentence 'Face book is a social networking company', which I want to clean by concatenating 'Face' and 'book' into 'Facebook'. I would like to check and perform this for numerous sentences. Any suggestions on how can I do this?
I thought of something on the lines of this: first tokenzing the sentence and then looping over every word and check if the token (word) after 'face' is 'book' and then delete the two elements and all 'Facebook'.
Wouldn't a simple regex based approach be sufficient?
>>> import re
>>> s='Face book is a social networking company'
>>> re.sub(r'[Ff]ace [Bb]ook', 'Facebook', s)
'Facebook is a social networking company'
Face book, face book and Face Book . :)
The most straight forward way of doing this in python, for me, would be using a tuple. Just pack all your strings into a tuple and loop through while applying the str.replace(old,new) method. str.replace(old,new) replaces a substring in the string str, with a new substring you specify. Example below:
Code:
string1 = "Face book is a social networking company1"
string2 = "Face book is a social networking company2"
string3 = "Face book is a social networking company3"
old = "Face book"
new = "Facebook"
superdupletuple = (string1, string2,string3)
for i in superdupletuple:
print(i.replace(old, new))
Output:
Facebook is a social networking company1
Facebook is a social networking company2
Facebook is a social networking company3
In Python, this might look something like this: (Keep in mind this is only a rough idea, it won’t be perfect in all cases)
——————————
string = “I use Face book”
tokenized = string.split(“ “)
for i in range(0,len(tokenized)-1):
if tokenized[i].lower()==“face” and tokenized[i+1].lower()==“book”:
del tokenized[i+1]
tokenized[i] = “Facebook”
if i > len(tokenized):
break
———————————
sentence.replace("Face book", "Facebook)
