An operator is a symbol that tells the compiler or interpreter to perform specific mathematical, relational or logical operation and produce final result.
Differentiation:
1. Interactive mode -
i) Interactive mode is used when a user wants to run one single line or one block of code.
ii) It runs very quickly and gives the output instantly.
1. Script mode -
i) Script mode is used when the user is working with more than one single code or a block of code.
ii) It takes more time to compile.
2. Relational operators -
i) Relational operators are used to perform comparison operations.
ii) There are six relational operators in Python which are >, <, >=, <=, = =, ! =.
2. Assignment operators -
i) Assignment operator is used to assign value of the second operand to first.
ii) Various assignment operators used in Python are (+=, - = , *=, /= , etc.)
Answer in 1-2 Sentence:
1. It was initially designed by Guido van Rossum in 1991 and developed by Python Software Foundation.
2. A particular kind of data item, as defined by the values it can take, the programming language used, or the operations that can be performed on it.
3. An input function is a function that takes an input (number, character or string) and stores that input value to a particular identifier.
Syntax = input()
2. A function which converts the expressions you pass into a string before writing to the screen is called as output function.

5. Operator precedence determines which operator is performed first in an expression with more than one operators with different precedence.
Answer Briefly:
1.
i) Easy to Learn and Use -
Python is easy to learn and use. It is developer-friendly and high level programming language.
ii) Expressive Language -
Python language is more expressive means that it is more understandable and readable.
iii) Interpreted Language -
Python is an interpreted language i.e. interpreter executes the code line by line at a time. This makes debugging easy and thus suitable for beginners.
iv) Cross-platform Language -
Python can run equally on different platforms such as Windows, Linux, Unix and Macintosh etc. So, we can say that Python is a portable language.
v) Free and Open Source -
Python language is freely available at
offical web address .The source-code is also available. Therefore it is open source.
vi) Object-Oriented Language -
Python supports object oriented language and concepts of classes and objects come into existence.
vii) Extensible -
It implies that other languages such as C/C++ can be used to compile the code and thus it can be used further in our python code.
viii) Large Standard Library -
Python has a large and broad library and prvides rich set of module and functions for rapid application development.
ix) GUI Programming Support -
Graphical user interfaces can be developed using Python.
x) Integrated -
It can be easily integrated with languages like C, C++, JAVA etc.
