Question
What is the output of the following program?ct1 = [x for x in range(6)]ct2 = [x for x in range(8) if x in ct1 and x%2==0]print(ct2)OptionsRuntime error[0, 2, 4][0, 2, 4, 6][0, 1, 2, 3, 4, 5]
Solution
The output of the program will be [0, 2, 4].
Here's the step by step explanation:
-
The first list comprehension
ct1 = [x for x in range(6)]generates a list of numbers from 0 to 5. So,ct1will be [0, 1, 2, 3, 4, 5]. -
The second list comprehension
ct2 = [x for x in range(8) if x in ct1 and x%2==0]generates a list of numbers from 0 to 7, but only includes those numbers in the list if they are also inct1and they are even. -
The numbers 0, 2, 4 are in
ct1and they are even, so they are included inct2. The number 6 is not inct1, so it is not included inct2. -
Therefore,
ct2will be [0, 2, 4]. -
The
print(ct2)statement then prints this list, so the output of the program is [0, 2, 4].
