We can create a NumPy array using aPython List. For example, importnumpyasnp# create a list named list1list1 = [2,4,6,8]# create numpy array using list1array1 = np.array(list1)print(array1)# Output: [2 4 6 8] Run Code In the above example, we first imported thenumpylibrary ...

Array Creation:Numpy provides us with several built-in functions to create and work with arrays from scratch. A typical numpy array function for creating an array looks something like this: numpy.array(object, dtype=None, copy=True, order='K', subok=False, ndmin=0) Here, all attributes oth...
NumPy Array Creation: NumPy’s main object is the homogeneous multidimensional array. It is a table of elements (usually numbers), all of the same type, indexed by a tuple of positive integers - w3resource
1. Masked Array CreationWrite a NumPy program that creates a masked array from a regular NumPy array with some specified values masked.Sample Solution:Python Code:import numpy as np # Import NumPy library # Define a regular NumPy array data = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9...
