for i in item: print(i, end=" ") print() In the above code: The “Numpy” module provides a function named “np.array()” to create a “1-D” and “2-D” array. The “for” loop iterates over the initialized array and the “print()” function is used to print the elements...

Now if you were to make changes to one of the arrays, it would not affect the other array, because after this point, both arrays are independent of each other. And this is how you can create a copy of an array in Python. >>> array2= np.array([[5,8,4,2],[3,7,9,0],[4,...
2. Get the Length of Array using len() Function in Python Pythonlen()is abuilt-infunction, which is used to get the total number of elements present in the given array. It returns a count of the index that is one more than the number of elements present in the array. ...
