In Python, a list is a data structure that is a mutable, or changeable, ordered series of elements. An item is any element or value contained within a list. Lists are defined by values between square brackets  in the same way that strings are defined by characters between quotations.
The main distinction between tuples and lists is that tuples are immutable objects, whereas lists are mutable. This means that tuples cannot be updated, whereas lists can be changed. Lists are less memory efficient than tuples.
A popular way to write the items of a list to a file in Python is to use a for loop to loop through the list's elements. Then, as part of each loop iteration, utilise a file object to write every element of the list to a file. It is necessary to open the file object in write mode.
A list is a data type that may hold several different sorts of data. A list is a composite data type, which means it can contain items of several data types. For example, a list can contain integer, float, and string elements.
Lists are used to organise data, with each data item separated by a comma (,). A Python List can include data elements of any data type, including integers and booleans. Lists are mutable, which is one of the main reasons for their popularity.
