Question
What is the output of the following program? ct = [x for x in (x for x in 'CT 22966 for CodeTantra' if x.isdigit()) if(x in ([x for x in range(20)]))]print(ct)Options[2, 2, 9, 6, 6]Compilation errorRuntime error[ ]
Solution
The code will result in a runtime error.
Here's why:
-
The outer list comprehension
[x for x in (x for x in 'CT 22966 for CodeTantra' if x.isdigit())]is trying to create a list of digits from the string 'CT 22966 for CodeTantra'. This part of the code works fine and will result in a list of strings: ['2', '2', '9', '6', '6']. -
The inner list comprehension
[x for x in range(20)]is trying to create a list of integers from 0 to 19. This part of the code also works
