• Naive Method. In the Naive method, one easily uses a loop that iterates through all the elements to check the existence of the target element.
• Check if an element exists in the list using count() We can use the in-built python List method, count(), to check if the passed element exists in the List.
• Check if an element exists in the list using sort + bisect_left + set. Converting the list into the set and then using it can possibly be more efficient than only using it.
• Using find() method. Python3. test_list = [10, 15, 20, 7, 46, 2808] print("Checking if 15 exists in list") x=list(map(str,test_list)) y="-".join(x)
• Using Counter() function. Below is the implementation: Python3. from collections import Counter. test_list = [10, 15, 20, 7, 46, 2808] frequency = Counter(test_list)
• Using try-except block. One additional approach to check if an element exists in a list is to use the index() method. This method returns the index of the first occurrence of the element in the list, or throws a ValueError if the element is not present in the list.
