Discussion on: Daily Challenge #39 - Virus

[Héctor Pascual]

Python :

import re

def fix_virus(document):
    doc = document.lower().capitalize()
    return re.sub(r'ie','ei',doc)

Python one-liner :

fix_virus = lambda doc : re.sub(r'ie','ei',doc.lower().capitalize())

If it's a document, it will contains multiple sentences and capitalize is only uppercasing the first letter of a string

[Héctor Pascual]

Ok then split document by lines and call the function :

document_splitted = document.split('\n')
for line in document_splitted:
    fix_virus(line)
    ....

Or capitalize each line of the document after lowering :)

Your solution is very good btw. Good job
