Extract number outside the parentheses in python

I have the problem with this string

'4.0718393*nt(placement5,placement6)+4.021677*nt(placement4)'

and want have this result

[4.0718393, 4.021677]

Simply said, I want to extract the numbers outside the parentheses in python. I found this regex pattern which will extract every number in a string and is not helping me get further.

re.findall("[-+]?\d+[\.]?\d*[eE]?[-+]?\d*", string) 

Much appreciated!

Does this answer your question?

import re

text = '4.0718393*nt(placement5,placement6)+4.021677*nt(placement4)'
matches = re.findall(r"\d+\.\d+", text)
