WebAppending items to and popping them from the right end of a Python list are normally efficient operations. If you use the Big O notation for time complexity, then you can say that they’re O (1). However, when Python needs to reallocate memory to grow the underlying list for accepting new items, these operations are slower and can become O ( n ).
