Why Are They Using Python?

Python’s popularity is one of the many reasons why organizations are readily using it for their development purposes. From keeping the application development cost in check to letting developers integrate AI and machine learning systems effectively, there are a lot of reasons why you can also consider using Python.

• Scalability: Scaling an application means that it needs to handle an increasing number of requests. Once the application code is written, rewriting or modifying the code is an arduous task.However, a Python app developer can easily write the adaptable code for the application being developed. With multithreading support and faster language scripting abilities, Python can be used to write code for simple tasks to complex applications.
• Frameworks: From building web applications to mobile applications, Python offers various frameworks to enhance development capabilities. These frameworks and libraries give Python the power it possesses today and will continue to do so in the future as well.We have already seen examples of applications using Django and Tornado for development purposes. Other than these two, Python application development frameworks like Flask, Web2Py, Pandas, Numpy, Turbogears are also important. 

• Code maintenance: Every programming language aims to make working with its code easier and simpler. The same applies to Python, and maintaining and updating the Python code is easier relative to other programming languages.This is because Python has a clear syntax, which allows writing cleaner code. Moreover, for Python code maintenance, you need to understand a few things;
  • Using Conda to implement Python dependencies.
  • Using different Python environments while coding makes it easier to maintain.
  •  Use Pytest and similar libraries to write testing systems for the code, which helps make it cleaner and more efficient. 

• Learning curve: Python has a flatter learning curve than other programming languages. Due to this, many programmers start using and learning Python initially before working with other languages.This is good for organizations as they get more options to hire Python experts and ensure that their developers are knowledgeable and well-trained. The developers can ensure this as they get more time and less difficulties learning the language.

• Diversity: From the list of top applications using Python, we can deduce that as a programming language, Python has many use cases. This enhances the net of Python development services while allowing organizations from several industries to use the language.There are live examples of Python’s usage in blockchain, artificial intelligence, machine learning, gaming applications, administration, business intelligence, streaming services, and many more.So, when a new organization is searching for their ideal programming language, they look towards Python and its usage among different industries. This convinces them to use Python.

• Availability of Developers: There are millions of Python developers out there. Besides helping you with application development, they can also work on web applications. The wide net of developers and python experts makes it easier to select the right people for the job. 

• Overall Development Experience: Developing an application with Python is faster and easier. There are several language-oriented capabilities like image processing, OCR, automated testing, integration with the latest technologies, and so on. The commiserative impact of these aspects makes the overall Python application development experience smoother and seamless. 

Conclusion

Python’s flexibility makes it the go-to programming language for building complex applications and for developers to start their careers in development. A programming language that satisfies the intent of organizations by offering quick development at lower costs and developers by giving them an easy programming environment, Python is an all-time favorite. 

With several global applications being built with Python, we can only hope for it to progress further and add more use cases to the list. Its compatibility with numerous libraries, frameworks, and tools further adds to the number of development possibilities.
