Return a new array of given shape filled with zeros and also set the desired output in Numpy
To return a new array of given shape and type, filled with zeros, use the np.zeros() method in Python Numpy. The 1st parameter sets the shape of the array. The 2nd parameter is the desired data-type for the array.
The dtype is the desired data-type for the array, e.g., numpy.int8. Default is numpy.float64. The order parameter suggests whether to store multi-dimensional data in row-major (C-style) or columnmajor (Fortran-style) order in memory. The like parameter is the 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.
Steps
At first, import the required library −
import numpy as np
To return a new array of given shape and type, filled with zeros, use the np.zeros() method in Python Numpy. The 2nd parameter is the desired data-type for the array −
arr = np.zeros((6,6), dtype = int)
Display the array −
print("Array...
",arr)Get the datatype −
print("
Array datatype...
",arr.dtype)
Get the dimensions of the Array: −
print("
Array Dimensions...
",arr.ndim)Get the shape of the array −
print("
Our Array Shape...
",arr.shape)
Get the number of elements of the Array −
print("
Number of elements in the Array...
",arr.size)Example
import numpy as np
import numpy.ma as ma
# To return a new array of given shape and type, filled with zeros, use the np.zeros() method in Python Numpy
# The 1st parameter sets the shape of the array
# The 2nd parameter is the desired data-type for the array
arr = np.zeros((6,6), dtype = int)
# Displaying the array
print("Array...
",arr)
# Get the datatype
print("
Array datatype...
",arr.dtype)
# Get the dimensions of the Array
print("
Array Dimensions...
",arr.ndim)
# Get the shape of the Array
print("
Our Array Shape...
",arr.shape)
# Get the number of elements of the Array
print("
Number of elements in the Array...
",arr.size)Output
Array... [[0 0 0 0 0 0] [0 0 0 0 0 0] [0 0 0 0 0 0] [0 0 0 0 0 0] [0 0 0 0 0 0] [0 0 0 0 0 0]] Array datatype... int64 Array Dimensions... 2 Our Array Shape... (6, 6) Number of elements in the Array... 36
