Welcome to the "GUESS THE OUTPUT" Series by 10 Minute Diploma
Here you'll have peace of code to solve on your own, later you'll get the output & explanation as well.
Explanation:
*************************************************************
x = [1, 2, 3]
x.append([4, 5])
x.extend([4, 5])
x.append(4)
print(len(x))
--------------------------------------------
Output:
4
⚪Explanation:
1. Initialization: x is initialized as [1, 2, 3].
2. Append Operation: The append method adds its argument as a single element to the end of the list. Here, [4, 5] is appended as a single element, making x now [1, 2, 3, [4, 5]].
3. Length Calculation: The len function returns the number of elements in the list x. Since [4, 5] is considered one element, the total number of elements in x is 4.
⚪Comments on the Commented Lines:
x.extend([4, 5]): If you uncomment this line, it will add 4 and 5 as individual elements to the list, making x [1, 2, 3, 4, 5]. The length would then be 5.
x.append(4): If you uncomment this line, it will add 4 as a single element to the end of the list, making x [1, 2, 3, [4, 5], 4]. The length would then be 5.
