What is Python & Why Does it Matter in Software Development?

Python is a programming language that was conceived in the 1980s by Guido van Rossum, moving from a simple scripting language to a mature and reliable language with extensive library and community support. Python has managed to not only retain consistent use in the past several decades, its use has grown, recently overtaking Java as the top programming language in October 2021.

What makes Python so popular? How has Python stood the test of time? This guide will answer the primary question of ‘What is Python?’ alongside an examination of what Python is used for, the benefits and disadvantages of the Python programming language, popular Python frameworks, as well as examples and use cases.

What is Python?

Python is known as an “interpreted, object-oriented, high-level programming language with dynamic semantics.” Let’s break that down:

• Interpreted– Each time the program is run, the interpreter processes the source code on the spot, line by line, halting if there are errors. The contrast to an “interpreted” language is a “compiled” language such as C# which translates the whole code in one go and reports errors collectively.
• Object-Oriented– An object oriented language (OOL) uses the concept of an “object” (data in the form of fields/attributes/properties and code in the form of procedures or methods) to make programming easier to develop, reuse and maintain.
• High-Level-level programming language uses strong abstraction from the computer instructions (e.g. natural language) to make it easier to use.

However, the above is a very technical description for what is ultimately a very simple programming language. Python is a very multi-purpose programming language, often earning the term of a “universal language.”

Software development in Python takes advantage of an easy-to-use English syntax, making it one of the more straightforward languages to learn – often favored as a first programming language for kids. Despite this simplicity, Python has the ability to support complex tasks and has far-reaching capabilities, features that have helped sustain consistent use and growth over time.

Python isn’t necessarily the best language in a given area–say, data science–but it’s good at a lot of things. Combine that with a syntax that’s easy to learn, and it’s not hard to understand why the language is growing. – Stephen O’Grady, RedMonk Analyst

What are the Advantages of Using Python

Is Python good for software development? As noted above, Python is considered a multi-purpose language – one that can be tasked to solve many different problems across a variety of different channels and platforms. Some of the benefits of Python software development include:

• Versatile, Easy and Fast to Develop
  Python is English-syntax based, easy to use and write, with versatile application.
• Open Source with Wide Community Support
  Extensive tutorials, guides, courses, and development forums create a wide base of support.
• Robust Frameworks and Libraries
  As a well-established and widely-used language, Python is well supported by robust frameworks and well-maintained libraries to streamline development for a wide variety of software needs, from websites to games to AI and machine learning.
• Rapid Prototypes
  As a simple, object-oriented language with well-supported libraries, Python allows for rapid prototyping – it simply takes less time to go from idea to prototype.
• Improved Productivity
  A large community, well-developed support materials, and the presence of many established frameworks and libraries make Python a dynamic scripting language: not one you build from scratch, but one you piece together. Additionally, the simplicity of the Python syntax structure supports rapid development and review.
• Portability
  Python can be run on nearly any computer / operating system.
• Code Readability
  The simple syntax makes Python code easy to read and review, streamlining bug fixes
• Automatic Memory Management
  Python uses automatic memory management methods to free excess memory during and after execution, reclaiming memory when objects are no longer needed.

The Main Disadvantages of Python

• Speed
  While Python may add speed to development, as an interpreted language, it can have overall speed limitations.
• Problems with Threading
  A thread is a flow of execution with a beginning and an end, but Python doesn’t support multi-threading – it does, however, support multiprocessing programs instead.
• Not Native to Mobile Environment
  Python is not a native programming language for iOS or Android, making mobile app development more problematic, and is often not as strong when it comes to UI development.
• Memory Consumption
  Python can place a heavy drain on memory, with developers needing to spend more time looking for memory leaks such as objects that are not properly released or leaks in various libraries in use. Python may not be ideally suited for tasks that involve a lot of memory or for tasks that use a large number of active objects.
• Database Access
  Python’s database access layer is not as well developed as other tools, particularly for legacy data.

11 Popular Python Frameworks and Tools

Python developers can use ready-made components in a framework to save time and money and accelerate time-to-market. Python has a wide scope of frameworks, libraries and tools available for developers.

There are two types of Python frameworks – full-stack frameworks and non-full stack frameworks. The full-stack Python frameworks give full support to developers from the user interface to the back-end data storage. In contrast, a non-full stack framework is a lightweight (under 5k) framework that does just one thing (but does it really well).

Here are 11 of the most popular Python frameworks and Python libraries, organized by their strengths:

Mathematics Libraries

There are several very popular math libraries for Python that supply more advanced math functions than the standard built-in Python Math Library.

• 1. NumPy
  NumPy provides math functions for arrays and matrices as well as functions that operate on arrays.
• 2. SciPy
  SciPy is a free, open-source library of modules for optimization, linear algebra, integration, interpolation, and various other functions of math, science and engineering.

Graphing Libraries

Data visualization libraries assist in development of various kinds of interactive, visually-appealing graphs.

• 3. MATLAB
  MATLAB is another scripting language, but its computational engine can be accessed for use in Python. MATLAB provides numeric computing as well as options to visualize data.
• 4. Seaborn
  A wrapper over matplotlib, Seaborn specializes in being simple and offering powerful visualizations.
• 5. Plotly
  Known for creating interactive plots and sophisticated charts, can be accessed from Python or on its own independent online platform.

Datatables Libraries

Datatables support manipulation of tabular datasets, an important element to speed up computing or build parallel computing systems.

• 6. Pandas
  Pandas is a fast, lightweight tool for data analysis and modeling.
• 7. Dask
  A comprehensive library that works in parallel with NumPy and Pandas, known for advanced parallelism for analytics.

Machine Learning Libraries

Data science is an evolving field, moving far beyond basic datatables into advanced artificial intelligence (AI) and machine learning (ML). There are an extensive number of ML libraries for Python due to the simplicity of the language, the top three being:

• 8. PyTorch
  PyTorch is based on Torch, a Facebook ML library for C wrapped in Lua, but now used by many big brands including Twitter. PyTorch supports computations, modeling, graphing, and ML concepts such as deep learning, NLP, Computer Vision and many more.
• 9. TensorFlow
  Developed by Google, TensorFlow is now an open-source library for computations and graphs and serves as a framework to develop neural networks and deep learning.

Websites, Web Apps and APIs

There are many popular Python web frameworks, but the two most popular are:

• 10. Flask
  Accessible under the BSD license, Flask is more of a “micro-framework” (not full stack), providing flexibility to developers to choose the tools, databases, and extensions to support a variety of functionalities.
• 11. Django
  Free, open-source full-stack framework to develop complex code and apps quickly. Django is considered one of the top Python frameworks
