Python_dict(plzzz explain it)

Question

D = {1 : {'A' : {1 : "A"}, 2 : "B"}, 3 :"C", 'B' : "D", "D": 'E'}
print(D[D[D[1][2]]], end = " ")
print(D[D[1]["A"][2]])

Answer 1

Second one is wrong tho,there is no key with D[1]["A"][2]
At key 1 there is 1:{"A":{1:"A"},2:"B"}
Inside it at key "A" there is "A":{1:"A"}
But there is no key inside it with 2

Answer 2

Ok first you should understand that end="" has no work here it basically used in range . Now let us start from beginning. You had declared a dictionary which contain dictionary itself . So here .

D[1][2] will first search for 1 key in dictionary now the value for key 1 is {'A':{1:"A"},2:"B"} ok now it will search for key 2 and the value for key 2 is B now your code will be simplified to D[D["B"]]

Now procedue further D["B"] will result in D and then it will be simplified to D["D"] so it will result in E because D Is keyword of value E .

Similarly do second one for your self
