Quick Summary : Python is one of the best programming languages. It is easy to use and satisfy diverse business needs. In this detailed guide on Python, we will understand basic concepts by understanding how to hire an expert Python developer based on different aspects.

Python’s simple, easy-to-learn syntax emphasizes readability and, therefore, reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms and can be freely distributed. Businesses can hire Python developers to take advantage of the diverse Python libraries available.

When something goes wrong in a Python program, instead of crashing the whole thing, Python raises an error message called an exception. This tells the programmer exactly where the problem is. If the program doesn’t know how to deal with the problem, it shows a list of what it was doing when it hit the issue. Python provides tools to help find and fix problems with debuggers. A debugger lets programmers look at what their code is doing step by step, check the values of different parts of the code, and even pause the program at specific points to see what’s happening. However, sometimes, the easiest way to find out what’s going on in a program is simply by adding print statements to show what the program is doing at different points. This quick cycle of making changes, testing, and debugging is one of the reasons why programmers love Python.

Disadvantages of Python:

Python is widely used because it’s easy to read and learn, and an extensive community supports it. It’s used for many things like web development, data analysis, and automation. But it has a few challenges that need to be considered:

Speed

Python is slower than other languages like C++ or Java because it’s interpreted, which means it is read and executed line by line by the Python interpreter. This makes tasks that need a lot of speed slower in Python, even though there are ways to make them faster with special libraries.

Global Interpreter Lock (GIL)

In Python, the GIL only lets one piece of code run at a time, even if your computer has many processors. This can make it harder to speed up your code using multiple processors.

Runtime Errors

Python can’t catch all mistakes before running your code, so errors might only appear while your program runs. This can lead to unexpected problems, especially in big projects.

Design Restrictions

Python’s way of doing things might be better for some programs. Other languages might be better for building software for machines or controlling hardware.

Mobile Development

While there are tools for making mobile apps with Python, it’s not as common as using languages like Java for Android or Swift for iOS. This means fewer resources and support for Python in mobile development.

Conclusion

Python is one of the widely utilized frameworks that help developers to create a feature-rich app. It is easy to learn and comes with diverse tools and libraries that help developers in the seamless development process.
