Question

1. Create a size-specific array of ones (10 , 1). Put the result into the bias array variable.
2. From the list [100, 50, 32, 1000], create an array. Put the result in the array from list variable array_from_list

# TODO 1.1

bias_array =

print(f"bias_array output: \n{bias_array}")

print(f"bias_array shape: {bias_array.shape}")

todo_check([

(bias_array.shape == (10,1),'bias_array does not have the shape (10, 1)'),

(np.all(bias_array == 1),'all values in bias_array are not 1')

])

#TODO 1.2

array_from_list =

print(f"array_from_list output: \n{array_from_list}")

print(f"array_from_list shape: {array_from_list.shape}")

todo_check([

(array_from_list.shape == (4,),'array_from_list did not have the shape (4,)'),

(list(array_from_list) == [100,50,32,1000],'array_from_list did not contain the values [100, 50, 32, 1000]')
