To avoid this, it is important to use the right method to find the element you are trying to act on. Finding an element using an index can help to avoid tests that produce inconsistent results. In this Selenium
C# List FindIndexThe FindIndex method returns the zero-based index of the first element that matches the predicate. If no element is found, it returns -1. public int FindIndex(Predicate match); public int FindIndex(int startIndex, Predicate match); public int FindIndex(int startIndex, int...
try: index = my_list.index(search_element) except ValueError: index = None print(index) # 2In this example, we used the index() method of lists to find the index of the first occurrence of the search element in the list. This method returns the index of the element if it is found...

FindLastIndex(Int32, Predicate<T>) 搜索与由指定谓词定义的条件相匹配的元素,并返回List<T>中从第一个元素到指定索引的元素范围内最后一个匹配项的从零开始的索引。 FindLastIndex(Int32, Int32, Predicate<T>) 搜索与指定谓词所定义的条件相匹配的元素,并返回List<T>中包含指定元素个数、到指定索引结束的...
By searching element i mean the value which i am looking for in the array. For example say we have an array Arr[5] = {1, 2, 3, 4, 5} and i am looking for 3 here in the array Arr. So 3 is the searching element. Last edited on Dec 14, 2016 at 12:10pm Dec...
In this example, we will take a list of elements (say strings). We will then find the last index of element"bc"in the list using List.lastIndexOf() function. Kotlin Program </> Copy fun main(args: Array<String>) { val list1 = listOf("ab", "bc", "cd", "bc", "de") ...
