Data Structures - I : Linear Lists — Question 2

NumLst = [2, 5, 1, 7, 3, 6, 8, 9]
SqLst = []
for num in NumLst:
    SqLst.append(num * 2)
print(SqLst)

[4, 10, 2, 14, 6, 12, 16, 18]

1. NumLst = [2, 5, 1, 7, 3, 6, 8, 9] — This line creates a list called NumLst containing the given numbers [2, 5, 1, 7, 3, 6, 8, 9].
2. SqLst = [] — This line initializes an empty list called SqLst.
3. for num in NumLst: — This line starts a for loop that iterates over each element num in the NumLst list.
4. SqLst.append(num * 2) — Inside the loop, each num is multiplied by 2, and the result is appended to the SqLst list.
5. print(SqLst) — This line prints the resulting list SqLst.
