numpy:array

Parameters

object : array_like

An array, any object exposing the array interface, an object whose __array__ method returns an array, or any (nested) sequence. If object is a scalar, a 0-dimensional array containing object is returned.

dtype : data-type, optional

The desired data-type for the array. If not given, NumPy will try to use a default dtype that can represent the values (by applying promotion rules when necessary.)

copy : bool, optional

If True (default), then the array data is copied. If None, a copy will only be made if __array__ returns a copy, if obj is a nested sequence, or if a copy is needed to satisfy any of the other requirements (dtype, order, etc.). Note that any copy of the data is shallow, i.e., for arrays with object dtype, the new array will point to the same objects. See Examples for ndarray.copy. For False it raises a ValueError if a copy cannot be avoided. Default: True.

order : {'K', 'A', 'C', 'F'}, optional

Specify the memory layout of the array. If object is not an array, the newly created array will be in C order (row major) unless 'F' is specified, in which case it will be in Fortran order (column major). If object is an array the following holds.

===== ========= ===================================================
order  no copy                     copy=True
===== ========= ===================================================
'K'   unchanged F & C order preserved, otherwise most similar order
'A'   unchanged F order if input is F and not C, otherwise C order
'C'   C order   C order
'F'   F order   F order
===== ========= ===================================================

When copy=None and a copy is made for other reasons, the result is the same as if copy=True, with some exceptions for 'A', see the Notes section. The default order is 'K'.

subok : bool, optional

If True, then sub-classes will be passed-through, otherwise the returned array will be forced to be a base-class array (default).

ndmin : int, optional

Specifies the minimum number of dimensions that the resulting array should have. Ones will be prepended to the shape as needed to meet this requirement.

ndmax : int, optional

Specifies the maximum number of dimensions to create when inferring shape from nested sequences. By default (ndmax=0), NumPy recurses through all nesting levels (up to the compile-time constant NPY_MAXDIMS). Setting ndmax stops recursion at the specified depth, preserving deeper nested structures as objects instead of promoting them to higher-dimensional arrays. In this case, dtype=object is required.

like : array_like, optional

Reference object to allow the creation of arrays which are not NumPy arrays. If an array-like passed in as like supports the __array_function__ protocol, the result will be defined by it. In this case, it ensures the creation of an array object compatible with that passed in via this argument.
