numpy.dtype¶

class numpy.dtype[source]¶

Attributes

alignment: The required alignment (bytes) of this data-type according to the compiler.
base: Returns dtype for the base element of the subarrays, regardless of their dimension or shape.
byteorder: A character indicating the byte-order of this data-type object.
char: A unique character code for each of the 21 different built-in types.
descr: __array_interface__ description of the data-type.
fields: Dictionary of named fields defined for this data type, or None.
flags: Bit-flags describing how this data type is to be interpreted.
hasobject: Boolean indicating whether this dtype contains any reference-counted objects in any fields or sub-dtypes.
isalignedstruct: Boolean indicating whether the dtype is a struct which maintains field alignment.
isbuiltin: Integer indicating how this dtype relates to the built-in dtypes.
isnative: Boolean indicating whether the byte order of this dtype is native to the platform.
itemsize: The element size of this data-type object.
kind: A character code (one of ‘biufcmMOSUV’) identifying the general kind of data.
metadata: Either None or a readonly dictionary of metadata (mappingproxy).
name: A bit-width name for this data-type.
names: Ordered list of field names, or None if there are no fields.
ndim: Number of dimensions of the sub-array if this data type describes a sub-array, and 0 otherwise.
num: A unique number for each of the 21 different built-in types.
shape: Shape tuple of the sub-array if this data type describes a sub-array, and () otherwise.
str: The array-protocol typestring of this data-type object.
subdtype: Tuple (item_dtype, shape) if this dtype describes a sub-array, and None otherwise.
