p>Slicing means extracting a part of the string by passing values between the square brackets []. For example:

An entity is called an object. Objects are defined as variables of suitable classes. For example, if we define a class student to represent students of a school, then each student of the school will be defined as an object of the class student.

A class is a collection of the objects/entities of the same type. A class represents the data members and the member functions collectively define entities of one type. For example, class of students, bunch of books, group of members etc can be defined to represent students, books, and members respectively.

List	Tuple	Dictionary
Mutable	Immutable.	Mutable
Have order.	Have structure.	A dictionary is a key-value store.
t=['Red','Green','Blue']	(1,'Krrishnav',90)	Dict={'Madrid':10,'Barcleona':20}

List are mutable and strings are immutable. Lists can be of any type of data i.e. integers, characters, strings etc, while strings can only hold a set of characters.

A dictionary is an ordered set of key:value pairs, where a key can be a number or a string and value can also be a number or a string. In Python a dictionary is created by putting the comma-separated key:value pairs of the dictionary in braces { }. For example, following is a small dictionary of three elements:

{'Dhoni':7, 'Kohli':18, 'Sachin':10}

A tuple is an ordered set of immutable heterogeneous elements. In Python a tuple can be created by putting the comma-separated elements of the tuple in parentheses().
For example, suppose we want to represent the following elements of a book with code: 1021, title 'Programming in Python', binding type 'Hard Bound', and edition 2018: As a tuple it is written as: (1021,'Programming in Python', 'Hard Bound', 2018).

A list is an ordered heterogeneous collection of elements. In Python, a list is created by putting the elements of the list in bracktes [ ].
For example, following is a list of five fruits:
['Grapes', 'Apple', 'Orange', 'Guava', 'Peach']

A string is an immutable sequence of zero or more characters (letters, numbers, symbols) enclosed within quotation marks (' ' or "").
