What is Python, and why is it needed?

Python is a popular programming language that is constantly evolving. It is flexible, readable, and straightforward.  You can write almost anything in Python, from web pages and games to a rover control system and the new Chat GPT. It is used by NASA, Facebook, Intel, Pixar, Instagram, and Google.

Python helps to solve complex and exciting problems in entirely different industries. At the same time, it has an intuitive and easy-to-remember syntax. Once you learn it, you can start by writing simple scripts or system administration and eventually move into machine learning, data analysis, or game development.

Python is the best option for beginners. So today, we’ll tell you more about why it’s so good and where else it’s used. You can start a new career by learning Python, too!

The reason why people adore Python

Python is a high-level, general-purpose, open-source, object-oriented programming language with an extensive standard library. The code written in it can be transferred to different platforms without changes. Now we can talk more about its advantages.

Advantages of Python

• Simplicity of syntax. Python is characterized by simple code. It reads like a strict English text.  Everything unnecessary has been removed from the syntax, so no excessive expressions and brackets exist. You’ll write fewer lines in Python than in Java or C/C++ to accomplish the same task. The simpler, the better. Especially for a beginner.
• A single standard (PEP8). There is a unique style guide for Python programming. It helps maintain the code’s readability and logic, even when several developers work with it.
• High performance. Simplicity and standards allow programmers to write fewer lines to accomplish more tasks.
• Interpretability. This means that the code is executed line by line (without compilation), and if there is an error, you will immediately see it and be able to fix it.
• An extensive standard library. It comprises many packages and modules for solving various tasks, from data processing to network programming and machine learning. You can find almost all the functions you need in the Python library.
• Portability. You can run programs on different operating systems (Linux, Windows, macOS) without changing the source code (if it does not contain system-dependent functions). Just write it once and enjoy it.
• A large community. A substantial active community of developers has formed around Python. They have created many tutorials, libraries, courses, and frameworks. You can always find answers to your questions, discuss work problems, and get support from like-minded people.
• Open source. You can download the source code for free, change something, and even distribute your version. This means that any programmer can participate in developing and improving Python and use it in projects without any license fees.
• Dynamic typing. Programmers do not need to declare a variable type in advance (unlike C++ or Java). Python will automatically assign a data type at runtime. This allows you to speed up development and testing and conveniently work with different data.
• Widespread use. Python is a flexible and versatile language. As we have already mentioned, it is used in completely different areas. This means that after studying, you can find a project you like. Try yourself in various industries and choose something.

Python is a great way to get started and the best proof that you don’t need to have superpowers to write code. But even in this case, it has its drawbacks.

Disadvantages of Python

No one is perfect, and Python is not 100 dollars to be liked by everyone. We tell you everything honestly, and you make your own decisions.

 4 disadvantages of Python

• Performance. This is the downside of interpretability and dynamic typing. Inline code and additional work during code execution make it slower than we would like. But this can be fixed by C-implementing problematic code sections.
• Memory consumption. The Python interpreter uses additional resources to manage dynamic typing and automatic garbage collection. This can lead to an increase in memory consumption.
• Imperfect support for some areas. Python may be less effective and popular, for example, in mobile development and the gaming industry. This is due to performance limitations.
• Global locking (GIL). One of the main performance issues in Python.  GIL locking allows the interpreter to be controlled only one thread at a time. This means multithreaded programs in this language may need help with parallel processing and multiprocessing.

Now, let’s see what is written in Python with all its pros and cons.

What tasks can be solved using Python?

Python’s versatility, simplicity, and versatility make it popular in many areas. Here are the main tasks it helps to solve:

1. Data visualization and analysis. Python boasts a large set of modules designed for analytical purposes. They make it easy to analyze and visualize data and study statistics.
2. Web development. Python allows you to develop functional websites and applications quickly and efficiently, especially if they do not require large amounts of computing resources.
3. Automation of tasks. Python allows you to write programs – scripts. They are customized for specific actions and save time.
4. Machine learning. Python is great for neural networks and machine learning. Its libraries allow you to perform visualization and complex data analysis. Moreover, simple artificial intelligence code in Python is more explicit and shorter than in other languages.
5. Scientific research.  Python is suitable, for example, for scientific computing, mathematical and textual analysis, and processing large amounts of data.
6. Testing. Python is often used to automate testing. It is like a Swiss knife for QA. It can test APIs, write UI tests, and generate the required data.
7. Software development. It is helpful at every stage of software development, from prototyping to testing and maintenance. Python’s flexibility makes it easy to refactor code and quickly turn a prototype into a final product.
8. System administration. First, Python is pre-installed on all servers running on OC Linux. Secondly, Python also allows you to automate many processes in this area.

As you can see, Python is simple, functional, and provides many opportunities for self-realization. That is why many of our students choose it.
