How to stop search after finding the first desired character and copy the rest text?

I've a string having CUSTOMER_SEGMENT_PRIV and want to get an output of CUSTOMER_SEGMENT equal to PRIV

>>> re.sub('_{1}',' ot lauqe ','CUSTOMER_SEGMENT_PRIV'[::-1])[::-1]
'CUSTOMER equal to SEGMENT equal to PRIV'
>>> re.sub('((?:_[^_\r\n]*){1})$',' ot lauqe ','CUSTOMER_SEGMENT_PRIV'[::-1])[::-1]
'CUSTOMER equal to SEGMENT equal to PRIV'

What I want: 

'CUSTOMER_SEGMENT equal to PRIV'

A shorter way using a good regex :

>>> import re
>>> re.sub( r'_([^_\r\n]*)$', ' equal to \\1', 'CUSTOMER_SEGMENT_PRIV' )
'CUSTOMER_SEGMENT equal to PRIV'

No need to use regex, just use str.rsplit with maxsplit=1 and str.join:

>>> s = 'CUSTOMER_SEGMENT_PRIV'
>>> x = s.rsplit('_', 1)
>>> x
['CUSTOMER_SEGMENT', 'PRIV']
>>> ' equal to '.join(x)
'CUSTOMER_SEGMENT equal to PRIV'
