strings.rjust(a, width, fillchar='')
Return an array with the elements of a right-justified in a string of length width.
Parameters:aarray-like, with StringDType, bytes_, or str_ dtypewidtharray_like, with any integer dtypeThe length of the resulting strings, unless width<str_len(a).
fillchararray-like, with StringDType, bytes_, or str_ dtypeOptional padding character to use (default is space).
Returns:outndarrayOutput array of StringDType, bytes_ or str_ dtype, depending on input types
Notes
While it is possible for a and fillchar to have different dtypes, passing a non-ASCII character in fillchar when a is of dtype “S” is not allowed, and a ValueError is raised.
