Python to Transforming elements in a list when split

Hello all… could you please help me with the question below?

Long_string = """
"Fifty Shades of Grey” shakeup: Kelly Marcel not returning for Sequel
"""

A need to break down the string into words. I do:

text_to_list = testing.split()

the output is:

['\xa1\xb0Fifty', 'Shades', 'of', 'Grey\xa1\xb1', 'shakeup:', 'Kelly', 'Marcel', 'not', 'returning', 'for', 'Sequel']

however some of those have special meanings when together, like the quoted “Fifty Shades of Grey”, and people’s name of together capitalized words like “Kelly Marcel”.

So I want to turn them into “Fifty-Shades-of-Grey” and “Kelly-Marcel” when they are split.

How can I do that? Thanks.
