struct.calcsize(fmt) Return the size of the struct (and hence of the bytes object produced by pack(fmt, ...)) corresponding to the format string fmt.

stringprep.map_table_b3(code) Return the mapped value for code according to tableB.3 (Mapping for case-folding used with no normalization).

stringprep.map_table_b2(code) Return the mapped value for code according to tableB.2 (Mapping for case-folding used with NFKC).

stringprep.in_table_d2(code) Determine whether code is in tableD.2 (Characters with bidirectional property “L”).

stringprep.in_table_d1(code) Determine whether code is in tableD.1 (Characters with bidirectional property “R” or “AL”).

stringprep.in_table_c9(code) Determine whether code is in tableC.9 (Tagging characters).

stringprep.in_table_c8(code) Determine whether code is in tableC.8 (Change display properties or are deprecated).

stringprep.in_table_c7(code) Determine whether code is in tableC.7 (Inappropriate for canonical representation).

stringprep.in_table_c6(code) Determine whether code is in tableC.6 (Inappropriate for plain text).

stringprep.in_table_c5(code) Determine whether code is in tableC.5 (Surrogate codes).
