"WebThe runtime complexity of the set.pop () function on a set with n elements is O (1). So, Python’s set.pop () method has constant runtime complexity. It simply removes and returns the first element it encounters. You can see this in the following simple experiment where we run the set method multiple times for an increasing number of set elements.

Web28 jul. 2024 · 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. WebThe worst-case time complexity is linear. Similarly, searching for an element for an element can be expensive, since you may need to scan the entire array. In this Python code example, the linear-time pop (0) call, which deletes the first element of a list, leads to highly inefficient code: Warning: This code has quadratic time complexity .
