Should we consider the time complexity of inbuilt functions and operations

Say I have a list and what to find an element: I could do this: if element in list: .......... Or I could write my own binary search function: So how do I know the time complexity of (in)

Every algorithm has its own time complexity. But here is one of many websites that tell you time complexity of the most common algorithms: https://www.bigocheatsheet.com/

Time complexity of "element in list" is O(n) as it is just a linear search... (you could also know its just a linear search as it works with unsorted lists too).. So if you want your code to operate quicker, you might consider making your own binary search function.

Aleksei Radchenkov is there a website where I can find a list of the time complexities
