What are the features of python programming language class 11?

Python is a dynamic, high-level, free open source, and interpreted programming language. It supports object-oriented programming as well as procedural-oriented programming. In Python, we don’t need to declare the type of variable because it is a dynamically typed language. For example, x = 10 Here, x can be anything such as String, int, etc.

Features in Python

There are many features in Python, some of which are discussed below as follows:

1. Free and Open Source

Python language is freely available at the official website and you can download it from the given download link below click on the Download Python keyword. Download Python Since it is open-source, this means that source code is also available to the public. So you can download it, use it as well as share it.

2. Easy to code

Python is a high-level programming language. Python is very easy to learn the language as compared to other languages like C, C#, Javascript, Java, etc. It is very easy to code in the Python language and anybody can learn Python basics in a few hours or days. It is also a developer-friendly language.

3. Easy to Read

As you will see, learning Python is quite simple. As was already established, Python’s syntax is really straightforward. The code block is defined by the indentations rather than by semicolons or brackets.

4. Object-Oriented Language

One of the key features of Python is Object-Oriented programming. Python supports object-oriented language and concepts of classes, object encapsulation, etc.

5. GUI Programming Support

Graphical User interfaces can be made using a module such as PyQt5, PyQt4, wxPython, or Tk in python. PyQt5 is the most popular option for creating graphical apps with Python.

6. High-Level Language

Python is a high-level language. When we write programs in Python, we do not need to remember the system architecture, nor do we need to manage the memory.

7. Extensible feature

Python is an Extensible language. We can write some Python code into C or C++ language and also we can compile that code in C/C++ language.

8. Easy to Debug

Excellent information for mistake tracing. You will be able to quickly identify and correct the majority of your program’s issues once you understand how to interpret Python’s error traces. Simply by glancing at the code, you can determine what it is designed to perform.

9. Python is a Portable language

Python language is also a portable language. For example, if we have Python code for windows and if we want to run this code on other platforms such as Linux, Unix, and Mac then we do not need to change it, we can run this code on any platform.

10. Python is an Integrated language

Python is also an Integrated language because we can easily integrate Python with other languages like C, C++, etc.

11. Interpreted Language:

Python is an Interpreted Language because Python code is executed line by line at a time. like other languages C, C++, Java, etc. there is no need to compile Python code this makes it easier to debug our code. The source code of Python is converted into an immediate form called bytecode.

12. Large Standard Library

Python has a large standard library that provides a rich set of modules and functions so you do not have to write your own code for every single thing. There are many libraries present in Python such as regular expressions, unit-testing, web browsers, etc.

13. Dynamically Typed Language

Python is a dynamically-typed language. That means the type (for example- int, double, long, etc.) for a variable is decided at run time not in advance because of this feature we don’t need to specify the type of variable.

14. Frontend and backend development

With a new project py script, you can run and write Python codes in HTML with the help of some simple tags <py-script>, <py-env>, etc. This will help you do frontend development work in Python like javascript. Backend is the strong forte of Python it’s extensively used for this work cause of its frameworks like Django and Flask.

15. Allocating Memory Dynamically

In Python, the variable data type does not need to be specified. The memory is automatically allocated to a variable at runtime when it is given a value. Developers do not need to write int y = 18 if the integer value 15 is set to y. You may just type y=18.

Short Answer type Questions [2 mark each]

Question 1:
Define Python ?
Answer:
Python is a high-level, interpreted, interactive and object oriented-scripting language.

Question 2:
Why Python is interpreted ?
Answer:
Python is interpreted because it processed at runtime by the interpreter and you do not need to compile your program before executing it. This is similar to PERL and PHP.

Question 3:
Is there a tool to help find bugs or perform static analysis ?
Answer:
Yes,

Pychecker is a static analysis tool that finds bugs in Python source code and warns about code complexity and style.
Pylint is another tool that checks if a module statisfies a coding standards, and also makes it possible to write plug-ins to add a custom feature.

Question 4:
Who developed Python?
Answer:
Python was developed by Guido van Rossum in the late eighties and early nineties at the National Research Institute for Mathematics and Computer Science in the Netherlands.

Question 5:
Why Python is Easy-to-learn?
Answer:
Python has relatively few keywords, simple structure, and a clearly defined syntax. This allows the student to pick up the language in a relatively short period of time.

Question 6:
Write any feature of Python library.
Answer:
Python library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh.

Question 7:
Write any one similarity between Python and OOPs
Answer:
Python supports most of the OOP concepts like encapsulation, inheritance and polymorphism.

It is normally interpreted by another computer program. However subsets of the language can be compiled.

Long Answer type Questions [4 mark each]

Question 1:
What is the Python programming language?
Answer:
Python is an interpreted, interactive, object- oriented programming language. It is often compared to Tel, Perl, Scheme or Java.
It is a scripting language like Php or Asp for developing applications. Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Question 2:

Answer:
Java v/s Python :

Python programs run slower than the Java codes, but Python saves much time and space. Python programs are 3-5 times smaller than Java programs.
Python is a dynamic typed language. Python programmers don’t need to waste time in declaring variable types as in Java.
Python is much more easy to learn than Java.

Disadvantages of Python are :

Python is not the best for memory intensive tasks.
Python is interpreted language and is slow compared to C/C+ + or java.
Python is not a great choice for a high graphic 3D game that takes up a lot of CPU.
Python is evolving continuously with constant evolution there is little substantial documentation available for the language.

Question 5:

Answer:
C+ + v/s Python

Comparison is same as that between Java and Python except the program length in python is 5-10 times shorter than that in C + + .

How do we make Python Scripts Executable ?
Answer:
Python scripts can be executed in two ways :

Open the script1.Py in IDE Editor and run the script in the frontmost window of the Python IDE by hitting the run all button.
