Question
Select the correct answerWhat will be the output of the following Python code?>>> ct={k: 'C' + str(k) for k in range(4)}>>> ctOptionsAn exception is thrown{0: 'C0', 1: 'C1', 2: 'C2', 3: 'C3'}{0: 'C', 1: 'C', 2: 'C', 3: 'C'}{0: '0', 1: '1', 2: '2', 3: '3’}
Solution
The correct answer is {0: 'C0', 1: 'C1', 2: 'C2', 3: 'C3'}.
Here's the step by step explanation:
-
The code is creating a dictionary using dictionary comprehension. The expression inside the curly braces {k: 'C' + str(k) for k in range(4)} is a dictionary comprehension.
-
The for loop (for k in range(4)) will iterate over the numbers 0 to 3.
-
For each iteration, it will create a key-value pair in the dictionary. The key is the current number (k) and the value is a string that starts with 'C' and ends with the string representation of the current number ('C' + str(k)).
-
So, for the first iteration (k=0), it will add the key-value pair 0: 'C0' to the dictionary. For the second iteration (k=1), it will add 1: 'C1', and so on.
-
The final dictionary will be {0: 'C0', 1: 'C1', 2: 'C2', 3: 'C3'}.
