Python is a must for students and working professionals to become a great Software Engineer
especially when they are working in Web Development Domain. I will list down some of the key
advantages of learning Python:
• Python is Interpreted − Python is processed at runtime by the interpreter. You do not need to
compile your program before executing it. This is similar to PERL and PHP.
• Python is Interactive − you can actually sit at a Python prompt and interact with the
interpreter directly to write your programs.
• Python is Object-Oriented − Python supports Object-Oriented style or technique of programming
that encapsulates code within objects.
• Python is a Beginner's Language − Python is a great language for the beginner-level
programmers and supports the development of a wide range of applications from simple text
processing to WWW browsers to games.
What Can Python Do?
We can achieve a lot by using Python as a programming language. Here’s a list of things we can
do with Python:
• Create web applications on a server.
• Create workflows along with software.
• Read and modify database systems.
• Solve complex problems and handle big data.
• Create rapidly-developed production-ready software.
Why Python?
You would wonder why use Python anyways? Let me help you understand using the keywords in the
formal definition of Python.
• High Level
Python derives components from the natural language that we humans use to communicate with each
other. This makes it easier for anyone to try and relate what exactly could be happening without
the burden of going through tons of machine code.
• Interpreted
Python codes are compiled line-by-line which makes debugging errors much easier and efficient.
But this comes at a cost as it is much slower than other programming languages.
• Easy Syntax
Python makes use of indentations instead of braces to distinguish what blocks of code come under
which class or function. This makes the code look well distributed and makes it easy for anyone
to read it.
• Dynamic Semantics
If you are an old school coder, you would know that before using anything, you would need to
initialize it. It does all of this dynamically.
Why learn Python
Python is not only one of the easier programming languages but is also incredibly powerful.
Although it was initially developed as a ‘scripting language’ – meant for trivial projects
rather than commercial use – it has since grown in popularity, largely because of the advent of
the internet. Python now powers some of the most popular sites on the web, including YouTube and
Google- it’s even used at NASA!
Python supports modules and packages, enabling the developer to design programs in modules and
reuse, scale, and export these modules for different projects.
It is also widely used by programmers developing new software in artificial intelligence,
automation and data science.
Why is Python mostly used for?
Python is often used as a support language for software developers, for build control and
management, testing, and many other ways.
Where is Python used in the real world?
The major fields include Machine Learning and AI, Web Development, Data Analytics, Game
Development, IoT, Application Development, and Game Development. Many sectors, including the
healthcare sector, finance sector, aerospace sector, and banking sector, rely heavily on Python.
What are the advantages of using Python?
• It's easy to read, learn and write. Python is a high-level programming language that has an
English-like syntax.
• Improved Productivity. Python is a very productive language....
• Interpreted Language....
• Dynamically typed.
• Free and Open-Source....
• Massive Library Support....
What are the disadvantages of Python?
The disadvantages of Python are:
• Python is slower than C or C++....
• Mobile Development. Python is not a very good language for mobile development...
• Memory Consumption Python is not a good choice for memory-intensive tasks...
• Database Access. Python has limitations with database access...
• Runtime Errors
Python's features include
• Easy-to-learn Python has a few keywords, a simple structure, and a clearly defined syntax.
This allows the student to pick up the language quickly.
• Easy-to-read Python code is more clearly defined and visible to the eyes.
• Easy-to-maintain: Python's source code is fairly easy-to-maintain.
• A broad standard library: Python's bulk of the library is very portable and cross-platform
compatible on UNIX, Windows, and Macintosh.
• Interactive Mode: Python has support for an interactive mode which allows interactive testing
and debugging of snippets of code.
• Portable Python can run on a wide variety of hardware platforms and has the same interface on
all platforms.
• Extendable: you can add low-level modules to the Python interpreter. These modules enable
programmers to add to or customize their tools to be more efficient.
• Databases: Python provides interfaces to all major commercial databases.
• GUI Programming: Python supports GUI applications that can be created and ported to many
system calls, libraries, and window systems, such as Windows MFC, Macintosh, and the X Window
system of UNIX.
• Scalable Python provides a better structure and support for large programs than shell
scripting.
How is Python used?
Understanding what Python is and why it should be used, you would wonder what you can do when
you master it. Well, the list is just surprisingly long. For instance,
• Creating web applications with Python Frameworks such as Django and Flask
• You can create workflows for the software that you are working on
• Use Python to modify files and data stored in Databases
• Scientific, Analytic and complex calculations can be taken care of easily
• You can create software much quicker with Python, which is ready for deployment.
Can Python be used to make apps?
Python can be used for Android App Development even though Android doesn't support native Python
development. This can be done using various tools that convert the Python apps into Android
Packages that can run on Android devices.
How Python is executed?
Python code is translated into intermediate code, which has to be executed by a virtual machine,
known as the PVM, the Python Virtual Machine. This is a similar approach to the one taken by
Java. There is even a way of translating Python programs into Java byte code for the Java
Virtual Machine (JVM).
How does Python actually work?
Python is called an interpreted language. Python uses code modules that are interchangeable
instead of a single long list of instructions that was standard for functional programming
languages. The standard implementation of python is called “cpython”. It is the default and
widely used implementation of Python.
