Python -- Lists and Tuples

 List and Tuple are built-in container types defined in Python. Objects of both these types can store different other objects that are accessible by index. List as well as tuple is a sequence data type, just as string. List as well as tuple can store objects which need not be of same type.

List : A List is an ordered collection of items (which may be of same or different types) separated by comma and enclosed in square brackets.

Tuple: Tuple looks similar to list. The only difference is that comma separated items of same or different type are enclosed in parentheses.

Differences between List & Tuple:

The obvious difference is the use of square brackets [] in List and parentheses () in tuple as enclosures. However, the important difference is that List as a mutable object and Tuple is an immutable object.

If contents of an object can be modified in place, after it has been instantiated, is a mutable object. On the other hand, any operation on immutable object that tries to modify its contents is prohibited.

Various methods to perform operations on list are below::

Append()	Appends an object to the end of the list
Copy()	Makes a copy of list
Count()	Returns number of occurrences of value in list
Extend()	Extends the list by appending elements from another list/tuple
Insert()	Insert objects in the list based on index
Pop()	Removes and returns last item at given index .Raises IndexError if list is empty or index is out of range.
Remove()	Removes first occurrence of value in the list. Raises ValueError if the value is not present.
Clear()	Removes all items from the list
