datatable.stype.

__new__

(

value

)

source

Find an stype corresponding to value.

This method is called when you attempt to construct a new dt.stype object, for example dt.stype(int). Instead of actually creating any new stypes, we return one of the existing stype values.

Parameters

value

str | type | np.dtype

An object that will be converted into an stype. This could be a string such as "integer" or "int" or "int8", a python type such as bool or float, or a numpy dtype.

return

stype

An dt.stype that corresponds to the input value.

except

ValueError

Raised if value does not correspond to any stype.

Examples

dt.stype(str)

stype.str64

dt.stype("double")

stype.float64

dt.stype(numpy.dtype("object"))

stype.obj64

dt.stype("int64")

stype.int64
