Q. Which of the following will result in an error for a given valid dictionary D?

(i)

D + 3

(ii)

D * 3

(iii)

D + {3 : "3"}

(iv)

D.update("3": 3)

Answer:-

Options (i), (ii), (iii), & (vi)

The explanation for (i):- We can not add the number to the dictionary because the dictionary has keys and value pairs.

Explanation for (ii):- We can not do arithmetic operations on the dictionary directly.

Explanation for (iii):- We can not directly add keys and value pairs. Correct way : D[3] = "3"

Explanation for (vi):- We have to pass the dictionary in the update function.
