Question: What are different Keywords in Python?

Answer: Keywords are special reserved words which convey a special&n
bsp;meaning to the compiler/interpreter. Each/>keyword have a special meaning and a specific operation.&n
bsp;List of Keywords used in Python are:/> />/>/>/>/>

Question: What is Python?

Answer: Python is an object-oriented, high level language, interpreted,&n
bsp;dynamic and multipurpose programminglanguage./>Key Features:/> 1.) It is easy to learn, powerful and versatile
;scripting language which makes it attractive for/>Application Development/> 2.) Its syntax and dynamic typing with its interpret
ed nature makes it an ideal language for/>scripting and rapid application development in many areas/> 3.) It supports multiple programming pattern including ob
ject oriented programming, imperative and/>functional programming or procedural styles/> 4.) It is not intended to work only on special&
nbsp;area such as web programming. That is why it is/>known as multipurpose because it can be used with web
, enterprise, 3D CAD etc/> 5.) We don't need to use data types to decl
are variable because it is dynamically typed so we/>can write a=10 to declare an integer value in a
variable/> 6.) It makes the development and debugging fast beca
use there is no compilation step included in/>python development and edit-test-debug cycle is very fast

Question: What are main features of Python language?

Answer: There are a lot of features provided by python programm
ing language. Some of the important features/>are given below:/> 1) Easy to Use: Python is very easy to u
se and high level language which makes it is/>programmer-friendly language/> 2) Expressive Language: Python language is more ex
pressive. The sense of expressive is the/>code is easily understandable/> 3) Interpreted Language: Python is an interpreted
language i.e. interpreter executes the/>code line by line at a time. This makes debugging&nbs
p;easy and thus suitable for beginners/> 4) Cross-platform language: Python can run equally
;on different platforms such as Windows,/>Linux, Unix , Macintosh etc which makes it a portable
language/> 5) Free and Open Source: Python language is f
reely available and redistributable/> 6) Object-Oriented language: Python supports object ori
ented language/> 7) Extensible: It implies that other languages suc
h as C/C++ can be used to compile the code/>and thus it can be used further in your python c
ode/> 8) Large Standard Library: Python has a large
;and broad library/> 9) GUI Programming: Graphical user interfaces applicati
on can be developed using Python/> 10) Integrated: It can be easily integrated with&n
bsp;languages like C, C++, JAVA etc

Question: What type of application can be developed using Python?

Answer: Python can be in developement of folloiwng types of app
lication: 1) Console Based Application/> 2) Audio or Video based Applications/> 3) 3D CAD Applications 4) Web Applications/> 5) Enterprise Applications 6) Applications for Images/>

Question: How to define/initialize variable in Python?

Answer: In Python we don't to declare variable explicitly. When&
nbsp;we assign any value to a variable that/>variable is declared automatically. variable can be directly&nb
sp;initialized without defining it. In/>Python, we can initialize variable in following ways:/> 1.) Individual Assignment: Example: a=100; /> 2.) Multiple Assignment: Example: x=y=z=55; [Same value
is assigned to all the variable x, yand z]/> 3.) Multiple Assignment with Multiple Values: Example:&
nbsp;x,y,z=10,15,20; [Values are assigned/>in the same order in which variables appears]
