WebPython List pop() Time Complexity. The time complexity of the pop() method is constant O(1). No matter how many elements are in the list, popping an element from a list takes the same time (plus minus constant factors). The reason is that lists are implemented with arrays in cPython. Retrieving an element from an array has constant complexity. WebSee Amortized time complexity for more on how to analyze data structures that have expensive operations that happen only rarely.. Expensive list operations. To add or remove an element at a specified index can be expensive, since all elements after the index must be shifted. The worst-case time complexity is linear.
