Pop() returns and removes the last element from the list if there is no index value passed. With the index of the element, call the pop() method to remove an item from a list. Pop() to grab the index of an item in a list in Python. Print("the element comes at index 0:", lst) However, Injecting a command of a try/except block before the call to index() might prevent this. Moreover, If there is no item in the list matching your search criteria, then it doesn’t exist. In addition, You’ll receive an error if Python can’t find the item you’re searching for in the list, a ValueError. Using an if-else statement, grabbing a specific index location is possible by passing an index location in a square bracket within the condition. without Enumerate function using if-else conditions – The output shows that at index 0…9 in the list, element values from 5…55 respectively present. – The 3rd element in the list, “15”, has an index of 2. – The 2nd element in the list, “10”, has an index of 1. – The 1st element in the list, “5”, has an index of 0. Print ("minute hand at %i: %i min" %(i,j)) By default counter in enumerate starts from the 0 index location.And print the command to print the output of the iterator we want to repeat over and over.Indices we want to print on output is comes in square brackets.List to return object value in the list.(i,j) a variable represents the current item we are on in the iteration.for loop to tell the pythonic command that we want to enter a for a loop.The execution process goes in the following sequence: Moreover, By using the enumerate function in Python, you create an enumerate object from a data collection object. This results in a number that can be indexed in a specific way. This function indexes/tags elements in lists, strings, and tuples. However, grabbing the index of an item in a list is possible by introducing enumerate() function in a list. Iterables are objects you can iterate over in Python. Furthermore, Python’s list() function returns a list from any iterable. Commas (,) and square brackets () separate the items in the list. In computing, a list is a collection of values or items. Index = for i in url].index(j) for j in url_index] Url = [['# define a list of elements whom index location is to be found
