python - How to remove parentheses only around single words in a string -


let's have string this:

s = '((xyz_lk) stuff (xyz_l)) (and more stuff (xyz))'

i remove parentheses around single words obtain:

'(xyz_lk stuff xyz_l) (and more stuff xyz)'

how in python? far managed remove them along text using 

re.sub('\(\w+\)', '', s)

which gives

'( stuff ) (and more stuff )'

how can remove parentheses , keep text inside them? 

re.sub(r'\((\w+)\)',r'\1',s)

use \1 or backreferencing.
