How to split each words from several lines of a word file? (python)

Question

I have a text file:

But soft what light through yonder window breaks
It is the east and Juliet is the sun
Arise fair sun and kill the envious moon
Who is already          


        

Answer 1

output = []
with open('file_name') as f:
    for i in f.readlines():
        for j in words_to_split:
            i = ''.join(i.split(j))
        output.append(i)
