Python is exactly that language which is well known or at least familiar among the masses, even with zero IT experience. It is interpreted, object-oriented, high-level programming language, with dynamic semantics, dynamic typing and binding, high-level built-in data structures. Python was released in 1991 and 27 years later it is still one of the most popular programming languages.
The biggest and well-known projects created on Python are YouTube (almost the entire codebase is written on Python), desktop Dropbox, Reddit, Quora, Spotify, Instagram, PayPal, NASA, Mozilla, Pinterest. The further developing of Python language is supported by such giants as Google, Dropbox, Mozilla, Facebook, Yandex, Red Hat, Microsoft and Intel, which made some resources predict the full domination of Python in web development by 2020.
Python has been an important part of Google since the beginning, and remains so as the system grows and evolves.
Being a whale of programming, Python is frequently estimated and, as usual, is at the top of the list:
- Python was announced as the second most popular programming language according to the PYPL PopularitY of Programming Language
- GitHub placed Python in the third place in the list of Top active languages;
- By the TIOBE Index for March 2018, Python is accredited as the fourth most popular programming languages;
- by results 2017, Python is the best programming language for web and mobile applications by the IEEE Spectrum ranking.
The networking site Reddit is written in Python entirely.
Python was built with a clear philosophy of beauty (in relation to the code) and with the idea to make the language simple, explicit, complex and readability. Such approach turned Python into one of the best languages to work. In addition to this, other benefits also deserve to be noticed:
- Extensive libraries provide working on string operations, Internet, web service tools, operating system interfaces and protocols;
- Third party modules allow to work and integrate with multiple systems and platforms;
- Object-oriented programming which is actually laid in the foundation of Python;
- Variety of frameworks for flexible web programming (Django is the most popular);
- Open source which means free-to-use.
Python use areas
- Web development. From small micro to macro web applications – everything can be built with Python.
- Software development. In case with Python, we talk about building control and testing software.
- Desktop GUIs (Graphical User Interfaces). Less popular, but thanks to such libraries as wxPython or PyQT, Python is still used for building desktop GUIs.
- Scientific and numeric. Using Python for analyzing almost all kind of data (weather, predicting matches scores, etc.).
And depending to which category your future product will belong to, developer or development team will have particular knowledge and be specialized in the solving specific tasks.

The skills testing is one of the key stages of hiring the IT specialist, including Python developer. The assigned task can check at once a few skills, which are especially needed for your project. In an example by Devskiller for mid-level programmers, knowledge of Python, web scraping, data analysis and Django is tested.
Input data: A compact customizable web scraper that takes a query (URL), scrapes the URL, and extracts the complete vocabulary of the document. In addition to displaying the extracted words in a table grouped by type (noun, verb, etc.) the app will display a graph showing word frequency across the collection of words.
- Get URL from USER;
- Scrape URL;
- Parse out only the content of the page (ignore html elements, tags etc.);
- Use a regular expression to extract all of the words;
- Use collections.counter to create a frequency count of all of the words;
- Get a words type (using NLTK library);
- Determine the number of times the word appears in the document;
- Create a table of all of the words;
- Use Matplotlib (/Seaborn) (or any other python visual library) to create a chart of the frequency of the 100 most common words;
- Display the data on a page.
Salaries & hourly rates
There are two main factors which influence the Python developer’s payments: location and experience/competence. The US remains the highest paid county for most specializations in IT. While the junior Python developers’ average salary in the States can reach $75,000, according to Indeed, the Senior developer earns about more than $100,000.
In Western Europe countries Python developers are also highly paid, in comparison with Eastern Europe, Latin America and Asia.
The second cost define criteria is experience level, depending on which the rates can be divided this way:
- Less than year – $70,131;
