Split a string with "(" and ")" and keep the delimiters (Python) [duplicate]

Question

Let's suppose I have this string:

s = "123(45)678"

How can I can get this list?

l = ['123','(','45',')','678']

Answer 1

If you were only interested in '(' or ')' then str.partition would have been sufficient.

Since you have multiple delimiters AND you want to keep them, you can use re.split with a capture group:

import re

s = "123(45)678"

print(re.split(r'([()])', s))
# ['123', '(', '45', ')', '678']

Answer 2

You can use re.findall:

import re
s = "123(45)678"
final_data = re.findall('\d+|\(|\)', s)
print(final_data)

Output:

['123', '(', '45', ')', '678']
