BetaIt is very common for me to loop through a python list to get both the contents and their indexes. What I usually do is the following: S = [1,30,20,30,2] # My list for s, i in zip(S, range(len(S))): # Do stuff with the content s and the index i I find this syntax a bit ugly, especially the part inside the zip function.

BetaThe most pythonic way to get both index and value is using the enumerate() function. This built-in function creates an iterator of tuples containing count and value. fruits = ['apple', 'banana', 'cherry'] for index, value in enumerate (fruits): print (f"Index: {index}, Value: {value} ") Index: 0, Value: apple Index: 1, Value: banana Index: 2 ...

BetaFind the Index Position of an Item in a Python List. Let’s take a look at how the Python list.index() method works. In this example, we’ll search for the index position of an item we know is in the list. Let’s imagine we have a list of the websites we open up in the morning and we want to know at which points we opened 'datagy'.

BetaWhat happens though when you don't know the index number and you're working with a large list? You can give a value and find its index and in that way check the position it has within the list. For that, Python's built-in index() method is used as a search tool. The syntax of the index() method looks like this: my_list.index(item, start, end)

BetaHowever, no such method exists for lists (as of Python 3.11). Search for a string in Python (Check if a substring is included/Get a substring position) To create a function that emulates the behavior of the find() method for lists, use the in operator to check if an item is in the list. The in operator in Python (for list, string, dictionary, etc.)
