partitions string into nonoverlapping substrings of length n.


generates substrings with offset d.


  • All the substrings generated by StringPartition[string,n,d] are of length n. Some elements at the end of string may therefore not appear in any substring.
  • StringPartition[string,UpTo[n]] partitions into substrings of length up to n, allowing the final substring to be shorter.
  • All elements of string appear in the substrings generated by StringPartition[string,n,1].
  • If d is greater than n in StringPartition[string,n,d], then elements in the middle of string are skipped.
