Question
What will be the output of the following Python code snippet?test = {1:'A', 2:'B', 3:'C'}del test[1]test[1] = 'D'del test[2]print(len(test))02Error as the key-value pair of 1:’A’ is already deleted1
Solution
The output of the Python code snippet will be 2. Here's the step by step explanation:
-
A dictionary named 'test' is created with three key-value pairs: 1:'A', 2:'B', 3:'C'.
-
The key-value pair 1:'A' is deleted from the dictionary using the 'del' statement.
-
A new key-value pair 1:'D' is added to the dictionary. Now the dictionary 'test' contains 1:'D', 2:'B', 3:'C'.
-
The key-value pair 2:'B' is deleted from the dictionary.
-
The 'len' function is used to print the number of key-value pairs in the dictionary. Since there are two pairs left (1:'D', 3:'C'), the output will be 2.
