To initialize a list in Python assign one with square brackets, initialize with the list function, create an empty list with multiplication, or use a list comprehension.

Python provides us with various ways of reversing a list. We will go through few of the many techniques on how a list in python can be reversed. Method 1: Using the reversed built-in function. In this method, we neither reverse a list in-place modify the original list , nor we create any copy of the list. Instead, we get a reverse iterator which we use to cycle through the list. Using the reverse method we can reverse the contents of the list object in-place i. This method directly modifies the original list.
Python Unique List – How to Get all the Unique Values in a List or Array
Lists need not be homogeneous always which makes it a most powerful tool in Python. Lists are mutable, and hence, they can be altered even after their creation. List in Python are ordered and have a definite count. The elements in a list are indexed according to a definite sequence and the indexing of a list is done with 0 being the first index. Each element in the list has its definite place in the list, which allows duplicating of elements in the list, with each element having its own distinct place and credibility.
Python list is an essential container as it stores elements of all the datatypes as a collection. Knowledge of certain list operations is necessary for day-day programming. To find an element in the Python list , use one of the following approaches. Python Linear search on the list. To find an element in the list, use the Python list index method, The index method searches an item in the list and returns its index.
