By yielding back the index and the element itself, we're creating an iterable generator object, which we can then loop over and extract elements (and their indices) from via the for loop. The Python enumerate() function allows you to loop over an iterable object, such as lists or dictionaries while accessing the item’s index position. Your Day class is a subclass of Enum.So, you can call Day an enumeration, or just an, Day.TUESDAY, and the like are enumeration members, also known as enum members, or just members.Each member must have a value, which needs to be constant. Note: For more information, refer to Python Itertools. One such itertools function is islice (). They make iterating through the iterables like lists and strings very easily. The key point here is - the yield keyword defines a generator, which is iterable. The enumerate() function in Python takes in a data collection as a parameter and returns an enumerate object. Python Itertools.islice () In Python, Itertools is the inbuilt module that allows us to handle the iterators in an efficient way. The enumerate function is one of the most convenient and readable ways to check the index in for loop when iterating over a sequence in Python. I += 1 # Or, rewritten as a method that accepts an iterable def our_enumerate( some_iterable, start= 0): The enumerate () function is one of the built-in functions in Python. Method-1: Using the enumerate() function. Looping with a counter variable/index - a classic in Computer Science! Typically, you'd either explicitly define a counter variable/index, and manually increment it on each loop, or you'd use some sort of syntactic sugar to avoid this process through enhanced for loops: some_list =
