What is Python?
Python is defined as an interpreted, high-level, object-oriented programming language having dynamic semantics. It is high-level built via data structures, that are combined with the dynamic typing as well as the dynamic binding. This makes it very attractive for the task of Rapid Application Development, and for being utilized as a scripting language to connect the existing components. Python is simple and easy to learn syntax that emphasizes readability and hence reduces the cost towards program maintenance.
The python language supports those modules and packages, that encourages the program modularity as well as code reuse. The Python interpreter along with the extensive standard library are easily available in the source or the binary form without any charge for all the major platforms, and it can be distributed freely. The programmers often fall in love with Python due to its increased productivity. As there is no compilation step, the edit-test-debug cycle is extremely fast. Debugging the Python program is very easy: any bug or a bad input would never cause any segmentation fault. Rather, when the interpreter comes to know of an error, it creates an exception. When a program does not catch up with the exception, then the interpreter prints a stack trace.
The source-level debugger then allows the inspection of the local and the global variables, the evaluation of the arbitrary expressions, the setting of the breakpoints, the stepping through a code a line, one at a time, and so forth. The debugger is also written in the Python language itself, thus testifying to Python’s introspective power. Whereas on the other side, often the fastest method to debug any particular program is to simply add a few of the print statements to the source. This quick edit-test-debug cycle makes the simple approach extremely effective.
Why use Python?
Let’s try to understand what features or characteristics make Python, one of the most accepted languages when it comes to programming. Below are some merits of this language over its counterparts.
Merits of Python language
As per the latest TIOBE Programming Community Index, the Python language is considered to be among the top 10 popular programming languages of the year. Python is a general-purpose as well as a high-level programming language. An individual can easily use Python to develop desktop Graphic User Interface applications, websites or web applications. Also, the Python language, allows one to focus on the core functionality of an application by taking into account the common programming tasks.
The easy syntax rules of Python language further make it simpler for the users to keep the code base readable and the application maintainable, at the same time. There are even several other reasons why one must prefer Python over other programming languages. These are as follows –
1) Maintainable and Readable Code
At the time of writing a software application, one must focus on the quality of the source code to simplify the updates and maintenance. The syntax rules of the Python language allow one to express the concepts without writing any additional code. Along with that Python, emphasizes the aspect of code readability, and it allows the programmers to use the English keywords rather than the punctuations. Thus, one can use Python to create custom applications without even writing any additional code.
2) Multiple Programming Paradigms
Similar to the other programming languages, Python supports many different programming paradigms. It even supports object-oriented and structured programming techniques. Python even features a dynamic type system as well as automatic memory management. All of the programming paradigms and the language feature aids the programmers to use Python for creating large and complex software applications.
3) Compatible along with leading Platforms and Systems
Presently, Python is supported by a wide range of operating systems. One can also use Python interpreters to run the code on specific platforms and tools. Python is an interpreted programming language. It allows the user to run the same code on a variety of platforms without the need for any recompilation. Hence, one does not have to recompile the code after making any alteration.
4) Robust Standard Library
The large and robust standard library gives Python an edge over the other programming languages. This standard library allows the user to choose from a variety of modules based on the needs of the user. Each module even enables the user to add functionality to the application without the need for writing additional code.
5) Open Source Frameworks and Tools
Python is an open-source programming language. It helps the user to curtail the software development cost to a great extent. One can also use the open-source Python frameworks, development tools, and libraries to curtail the development time without an increase in the development cost. One can easily accelerate the desktop GUI application development by using Python GUI frameworks as well as tool kits such as PyQT, PyGUI, PyJs, PyGTK, Kivy, and WxPython.
6) Simplify the complex Software Development
Python is a generic purpose programming language. One can use python to develop desktop or web applications. One can make use of Python for developing of complex scientific as well as numeric applications. Python is created with features that facilitate the process of data analysis and data visualization. One can take advantage of the data analysis feature and create a custom big data solution without any extra time and effort. The data visualization libraries as well as the APIs help to visualize and present the data more appealingly and effectively. Many of the Python developers even use the Python language to accomplish artificial intelligence (AI) and natural language processing tasks.
- Limited server interaction − can easily validate the user input before sending a page off to a server. This helps to save a great deal of server traffic, which leads to less load on the server.
- Instant feedback to the user’s − users does not have to wait for the page to reload to see if they have missed out on entering any details.
- Increased level of interactivity − one can create multiple interfaces which react when a user hovers over any of them with a mouse or activates the same via a keyboard.
- It is an object-based programming language as it has predefined objects.
- It offers the user better control over the browser.
- It can manage dates and time.
- It is useful for detecting the user’s browser as well as OS,
- Java-Script does not have procedural programming whereas Python has it.
- Python has a newline while the Java-Script has a statement terminator.
- Java-Script is an excellent tool for mobile development whereas Python is not.
- Java-Script mainly functions on the floating-point variables whereas, Python has the support for several numeral data types such as float, int, fixed-point decimal.
