Answer 1

We can do a simple experiment on this.

Averagely speaking, it seems that your second code runs faster than the first one, but they both run very fast (each takes less than 1 ms), so you can choose the code you like, and get similar performance.

Answer 2

Why you comparing for the fastness. Both perform different operations..

In first, you removing last element jus from a list.

In 2nd, you are copying 0 to last element into a variable from a tuple. It is more operations than 1st.

Since there is just 3 elements no difference. But I think not comparable for fastness..

Answer 3

Thanks

Answer 4

Hello World
Good thinking.. I think those are 2 different operations but checked with time differences the pop operation taking more nano milliseconds than 2nd way slicing...
Hope this helps...
