These objects (called "result objects") are the variables created by a declaration (like a1), artificial objects created when the initialization ends up being discarded...

You can also write:
[e] * n

Performance testing
At first glance it seems that repeat is the fastest way to create a list with n identical elements:...

Breaking out of a nested loop

int i = 0;
