Numpy Quiz

Why use Numpy instead of python lists? (Choose all that apply)

if array = np.arange(3,7) What is the output of len(array)

How many dimensions are there in array ‘a’?

a = np.array([[3,3,0,3,3]])

What will be the output of b.flatten() if

b = np.full((3, 2), 7)

What is the result of np.vstack((a, b,c))

a = np.arange(4).reshape(2 , 2)
   b = np.arange(4,8).reshape(2,2)
   c = np.arange(9,13).reshape(2,2)

What is the value of nums after we do:nums[2:4] = [5, 6]

Suppose
nums = list(range(5))

What value is at a[1][2]

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

What is the result of np.sum(x)

x = np.array([[1, 2, 3], [4, 5, 6]])

What is the result of x + y

x = np.array([[1, 2],[3, 4]]) 

y = np.array([[5, 6],[7, 8]]).
