   What is Ravel() function?

   • The ravel() function accepts an array and returns a 1-D array containing the elements of the input array: In this syntax: a is a numpy array. It can be any array-like object e.g., a list. An array-like object is an object that can be converted into a numpy array. order specifies the order of elements.

   What is the syntax of Ravel() method?

   • The syntax of ravel() is: The ravel() method takes two arguments: The ravel() method returns the flattened array. Output [0 1 2 3 4 5 6 7] The order argument specifies the order in which the array elements are flattened. The order can be: 'A' - tries to preserve the original array's order, otherwise defaults to C-order.
