1) Fix the code below:

def hello Factory(greeting type):

my-duct { polite: \"Hello\", \"other\": hey}

return my_dict.greeting_type

my greeting - hello Factory(\"polite\")

print(my greeting) // Should print \"Hello\"

2) Fix the code below:

class Point4D()

_init__(w, x, y, z):

self.W=W

self.X=X

self.y= y

self.z = z

_str__(self) :

Print ({},{},{},{} format(self.w, self.x, self.y, self.z))

my-4d-point= Point4D( 1, 2, 3, 1)

print(my-4d-point) # should print '1, 2, 3,1
