Regex python remove the left side of text beginning with hyphen or curved brackets

I am stuck on this rather simple regex string issue for hours.

I have a string and I need to remove the left side of text in all occurrence of hyphen "-" or curved brackets "()"
I am able to remove the brackets but I can’t figure out how to remove the hyphen as well.
Below is my attempt

import re
sentence = re.sub(r"\([^()-]*\)", "", 'P. Test data-I am using-(regex)(python)')
print(sentence)

Output

P. Test data-I am using-

The output I need is

 P. Test data

Thank you for your help.

>Solution :

You can use str.partition:

>>> 'P. Test data-I am using-(regex)(python)'.partition('-')[0]
'P. Test data'
