numpy.sctype2char(sctype)

Return the string representation of a scalar dtype.

Parameters:

sctype : scalar dtype or object

If a scalar dtype, the corresponding string character is returned. If an object, sctype2char tries to infer its scalar type and then return the corresponding string character.

Returns:

The string character corresponding to the scalar type.

Raises:
