This article mainly introduces how to find the position of an element in a list using Python, which is of great reference value and hopefully helpful to everyone. How to Find the Position of an Element in a List Problem Description Given a sequence containing n integers, determine the position...
list, and set. Various operations, such as access location, manipulation, and elimination are performed in the programming language on particular elements of a given data set. Python also supports these features and one of them is to get the exact position of an ...

Finding the index of an item in a list: In this tutorial, we will learn how to find the index of a given item in a Python list. Learn with the help of examples.
It returns the value of the removed object. Calling .pop() without arguments removes and returns the last item in the list: Python >>> a = ["a", "b", "c", "d", "e"] >>> a.pop() 'e' >>> a ['a', 'b', 'c', 'd'] >>> a.pop() 'd' >>> a ['a', 'b'...

Similarly, when you pass an object to the built-in repr() function, you get a developer-friendly string representation of the object itself: Python >>> repr(42) '42' >>> repr(3.14) '3.14' >>> repr([1, 2, 3]) '[1, 2, 3]' >>> repr({"one": 1, "two": 2, "three":...
