string.pfind()

[DESCRIPTION]


     
   1  string.pfind( pt :string, index = 0, start = 0, end = 0 )=>list<tuple<start:int,end:int> >
     

This method searches for the position(s) of substring(s) that match(es) to the pattern
represented by pt. If index is greater than zero, search for the index-th occurrence of 
the matched substring, otherwise, search for all. The searching starts from position 
start, and ends at end if it is greater than zero. Zero value for end indicates 
searching until the end of the string.
