Remove certain word using regular expression

Question

I have a string which is shown below:

a = 'steven (0.00030s ). prince (0.00040s ). kavin (0.000330s ). 23.24.21'

I want to remove the numbers inside () and the brackets and want to have it like this:

a = 'steven  prince  kavin  23.24.21'

Use re.sub

Ex:

import re
a = 'steven (0.00030s ). prince (0.00040s ). kavin (0.000330s ). 23.24.21'
print(re.sub(r"(\(.*?\)\.)", "", a))

Output:

steven  prince  kavin  23.24.21

Why the outer group? Why `.*?` rather than `.+`? – Martin Bonner supports Monica May 21 '19 at 12:48

Personally I would go for a much more restrictive RE: `\([0-9]+\.[0-9]s \)\.` – Martin Bonner supports Monica May 21 '19 at 12:49
Ah, yes. But `.*` will match "nothing inside the brackets" too (I was confusing `.*?` with `.*.?` which is equivalent to `.+`) – Martin Bonner supports Monica May 21 '19 at 12:50
