For uses more complex than basic partitioning, people should shift to
more powerful tools like re.finditer(), re.findall(), and re.split().

I prefer to avoid variants that are searching of a purpose.

That case should be handled with consecutive partitions:
# keep everything after the second 'X'
head, found, s = s.partition('X')
head, found, s = s.partition('x')
