Getting started with Python
- Getting Started
Python is considered to be one of the programming languages that are easy to learn, grasp, and implement to develop
real-world projects from the perspective of a beginner.
Python; being a platform-independent programming language,
is easier to use across multiple operating systems whether it be Windows, Linux, or Mac.
- Python is a high-level programming language and is open-source i.e; available for free
- It follows an object-oriented approach; which is considered to be one of the best programming paradigms.
- It is also an interpreted language i.e; the Python programs are executed by an interpreter
- It is case-sensitive i.e; CODE, and code are not the same in Python
- It is portable, and platform-independent i.e; it can run across different operating systems, and hardware
- Indentation is used for blocks and nested blocks. This plays a significant role in the entire program. If
there's any mistake with the indentation, an error occurs and as a result, the program does not execute.
- robustness; when the program goes through an error and crashes, the useful information regarding the reason
behind the program to crash is shown including the exact line where the error has occurred.
Python is one of the most popular programming languages. It has applications in multiple domains ranging from web
development to advanced data science, and machine learning, etc. Commonly, Python is used for developing websites,
software, automating the tasks, analyze, and visualize the data.
- Web Development
In the domain of web development, Python can be seen to be implemented for backend development. The most
commonly used Python frameworks for web development are Django and Flask.
- Automation or scripting
If there's any task that needs to be done repeatedly, it can be done more effectively, and efficiently using
Python. All of the automation processes can be written in the form of codes. Python can be used to automate
simpler tasks to complex ones as a result consuming time and human efforts.
- Data science
Python has become a synonym for people pursuing careers in data science. The complex statistical calculations
are reduced through Python. Besides that, different data visualizations are created, and the data present are
manipulated, as well as analyzed. There are various data visualizations such as 3-D plots, pie-charts, etc. that
can be generated using Python.
- Software testing
In the software development industry, besides creating and developing software, Python is also used to automate
testing, track bugs, etc. The most commonly used Python tools for software testing are Green and Requestium.
- Game development
The domain of game development is also touched by Python. Although the games developed using Python don't look
like professional ones, it explains a lot regarding the overall functional aspects of simple games.
Advantages of Python
- supports plenty of libraries
- can be used in different domains including data science, machine learning, web development
- open-source and community-driven
- easy to read, write, and code
- portable across different types of operating systems
In order to execute Python in your local device, it first needs to get installed in your local device. You can
download the latest version of Python as per your device's requirements.
- Once you've got Python installed in your device from the executable file, you can enter the
Python shell by typing 'python' on the Command Prompt.
- After you're inside the Python shell, you are good to go with code execution.
Most of the Linux has got Python pre-installed, meaning you do not have to bother installing it. In
order to get into the Python shell, all you need to do is type 'python' in the Terminal.
Let's code: A simple `Hello World` Python Program
Once you've got the Python installed in your local machine, you're ready to get started with the first-ever
Python program; the popular "Hello World" program!
The above program displays the text "Hello Python" once it is executed in the Python shell. This is possible due
to the built-in function 'print()'.
