Python Programming language
In this article, let us see one important Web development oriented Programming language which is used in school, Colleges and in companies as a favorite and easiest one.
What is Python?
Python is a multi-paradigm programming language. It also supports Object-oriented programming, structured programming and logic programming. Thanks to Guido van Rossum for introducing Python Programming Language.
Different versions of Python is supported by Python Software Foundation(PSF).
Python has risen to the top 3 list of TIOBE index of language popularity.
Even without prior knowledge of any computer programming language one can start to use Python.
As the online Work and demand is increasing, the programming language which is supporting these demands is also highly needed. Even though it is a scripting language, it also supports structural programming and Oops concepts, Python supports dynamic typing, [in some other programming languages modification in the programs or correcting the program is not easy, you need to open the program with it’s environment set up, make the changes you need then you need to save it and execute it].
It can be integrated with other programs easily. It provides cross platform compatibility. You can write Python program like a human communicating language, it’s syntax are developed with less complexity and provides more integrity,
In Python everything is an object.
We can install python using the official website of Python.
The official home of the Python Programming Language is an Open source community . Many independent programmers are supporting by creating new modules and improving the functionality to meet the new demands and updations.
The Python Package Index (PyPI) is a repository of software for the Python programming language. PyPI helps users find and install software developed and shared by the Python community.
We can learn the Python basics in the official website itself.
Google also provides an opportunity to learn Python on our own.
Python and its modes
What are the modes of Python?
Python has two basic modes: script and interactive. The normal mode is the mode where the scripted and finished ” . py” files are run in the Python interpreter.
The triple arrow symbol “>>>” is called a prompt, it indicates the readiness of the computing system to your instructions, process it and displaying the result.
In Python Datatype declaration is not taking more important role as it classify the datatype on its own and perform the function. But we need to know the limitations of the function (which are all permitted) and how we can use the function or operation.
The sample code given in the above image is given below:
>>> 1056 -739
>>> 306 * 872
FastAPI is a Python framework and set of tools that enables developers to use a REST interface to call commonly used functions to implement applications. It is accessed through a REST API to call common building blocks for an app.
Python and Java
Java is statically typed, whereas Python is dynamically typed. Java offers limited string-related functions, whereas Python offers lots of string-related functions. Java language uses curly braces to define the beginning and end of each function and class definition, whereas Python uses indentation to separate code into separate blocks.
Java is the faster language, but Python is simpler and easier to learn.
Python Front end or back end
Python can be used to develop both front-end and back-end applications.
Python and Web development
Python software catches errors quicker than other programming languages. It erases the need for long code-test-debug sessions. It also contains advanced features to streamline the programming process.
Python is commonly used for developing websites and software, task automation, data analysis, and data visualization. Since it’s relatively easy to learn, Python has been adopted by many non-programmers such as accountants and scientists, for a variety of everyday tasks, like organizing finances.
Programmers can use Python for server side web development.
Job categories that highly need Python includes
- Game developer
- Web designer
- Python developer
- Full-stack developer
- Machine learning engineer
- Data scientist
- Data analyst
- Data engineer
- DevOps engineer
- Software engineer
- Many more other roles
For Data Science
For Machine Learning
Python for machine learning is a great choice, as this language is very flexible: It offers an option to choose either to use OOPs or scripting. There’s also no need to recompile the source code, developers can implement any changes and quickly see the results.
Day by day the usage of Python by Software Developers and also by non programmers. Different Packages are helping to work with other Softwares and to meet the different needs for different applications.
Python has different packages, they can be used with different concepts.
- Data analysis with packages such as pandas and NumPy
- Data visualization using matplotlib or Seaborn
- Machine learning with Scikit-Learn, Keras, SciPy, PyTorch and TensorFlow
- Natural language processing using nltk
Other advanced Python programming courses will cover topics such as decorators, regular expressions, interfacing with web applications using Django and Flask, and conducting statistical analysis.
