the code for dictionary data type is wrong …as the key is always surrounded by double quotes “key” correct code:- a = {“1”:“first name”,“2”:“last name”, “age”:33} #print value having key=1 print(a[“1”]) #print value having key=2 print(a[“2”]) #print value having key=“age” print(a[“age”])

@Shubham, This is not necessary. Double are required compulsory for text/strings whether you use them as Key or Value. Whenever you are using numeric as key or value, it is not mandatory that you have to use double quotes but if you are using string then you have to use it. For ex.: Case 1 : Numeric as Key without quotes and String as value a={1:“One”,2:“Two”,“Age”:35} >>> a[1] ‘One’ Case 2: Numeric as Key in quotes and String as value >>> a={“1”:“One”,2:“Two”,“Age”:35} >>> a[“1”] ‘One’ Case 3: String as Key and Numeric as value >>> a={“One”:1,2:“Two”,“Age”:35} >>> a[“One”] 1 Hope it is clear. Thanks
