# I created this code to find the middle element's index of any list .

If the number of element's is an even number it will show index number of two middle elements and if it is an odd number it will show the middle element's index number Is this code correct ? Is there any other easy method ? Help me ☺️ https://code.sololearn.com/cg1b850Jg0CL/?ref=app

Sure! It is correct and clear... Just replace all slashes with double slashes, so the result will be integers

def mid(arr) : if len(arr) <3: return arr return mid(arr[1:-1]) print(mid([1,3,5,7,78,5,8,6])) find middle wirhout index.

Never use built-in names as variable names. list is the name of the base class of all list intances and you should never use that name as identifier. When the list is empty wrong indeces are shown but the code works perfectly otherwise. There are shorter and less redundant ways to write that code, but yours isn't bad. Also follow Bilbo Baggins' advice.

You can take advantage of the fact that integer division // returns the same value for two consecutive numbers. To simplify your code, you can check this example. I am not sure why you need the actual indices. If you want the middle elements, you can also directly slice a list using similar formula. https://code.sololearn.com/ciO4voCEXpOZ/?ref=app

The answer is easier than that: print(len(items)//2) Hope i helped

items = [2, 4,6,8, 10, 12, 14] num = len(items) // 2 print(num)
