String and word manipulation in Python

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'.

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

———————————

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'

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
