python - string conversion array and comma delimited

I have data in python that needs to convert string from

string = "[-8.27104300e-02  9.09485668e-02  7.72242993e-02]"

to this

converted_string = "-8.27104300e-02, 9.09485668e-02, 7.72242993e-02"

Basically removing brackets [] and putting in comma for the spaces

How do I achieve this ?

You don't need regex for removing the braces. That's just a simple slicing operation. However, I could see the need for it when substituting whitespace, especially when you have varying width whitespace separators.

>>> import re
>>> re.sub('\s+', ', ', string[1:-1])


'-8.27104300e-02, 9.09485668e-02, 7.72242993e-02'

However, if you can guarantee a fixed separator width of 2 spaces, then str.replace works well here -

>>> string[1:-1].replace('  ', ', ')
'-8.27104300e-02, 9.09485668e-02, 7.72242993e-02'
