# Define a function to find the kth largest element in a listdefkth_largest_el(lst,k):# Sort the list in descending order (reverse=True)lst.sort(reverse=True)# Return the kth largest element (0-based index, so k
This article mainly introduces how to find the position of an element in a list using Python, which is of great reference value and hopefully helpful to everyone. How to Find the Position of an Element in a List Problem Description Given a sequence containing n integers, determine the position...

1、find_element使用给定的方法定位和查找一个元素 2、find_elements使用给定的方法定位和查找所有元素list 常用定位方式共八种: 1.当页面元素有id属性时,最好尽量用by_id来定位。 2.XPath很强悍,但定位性能不是很好,所以还是尽量少用。如果确实少数元素不好定位,那还是选择XPath或cssSelector。
The target element variable, the indexes of whose matching elements we will find, is defined below: target_element=2 Example 1: Determine Index of All Matching Elements in List Using for Loop & enumerate() Function In this first example, we will use afor loopalong with theenumerate() functi...
