function2 = np.split()
function3 = np.extract()
function4 = np.stack()
function5 = np.transpose()

# nditer function is used for iterating through elements of array.
# This function help us to solve some basic Issues which we face in iteration
# when we want to iterate through nD array we need to use n for loops which can be difficult to write for arrays
# with very high dimensionality.

# Function #1 :
arr = np.array([[[1 , 2 , 3] ,
                 [4 , 5 , 6]],
                [[7 , 8 , 9] ,
                [10 , 11 , 12]]])

# Example #1 (working)
for i in np.nditer(arr) :
    print(i)
print("The Shape of Array is :" , arr.shape)
