What are some python based projects

Python - The most important questions for beginners

Python has now become the most popular computer language. Because it supports future-proof technologies such as the Internet of Things, industrial automation solutions, machine learning and AI projects, it will soon become even more important.

What is python

Python is a programming language that was developed by the Dutch web designer Guido van Rossum and launched on the market in spring 1991. Version 3.9.1 is currently available (as of December 2020). The free, universally usable and easily readable language is dynamic and open source. Programmers from all over the world are working on it and developing it further. The first complete version of the scripting language named after the comedian Monty Python appeared in 1994. So that Python programs can be integrated as modules in other computer languages, van Rossum also wrote a standard library.

Where and in which professions is it used?

Many popular applications such as DropBox, Instagram and YouTube use the Python code. Because it is designed for cross-platform operating systems, the desired programming can be easily created. Therefore it is suitable for almost everything that needs to be programmed. Even apps for the Android operating system, user interfaces, data analysis and automation solutions can be developed with it. It is also used for the following areas:

  • the web development
  • the web scraping
  • the development of new games
  • Business applications
  • -Artificial intelligence (AI) projects and machine learning
  • statistical purposes (data science)
  • CAD applications

Applicability for new websites

For the Creation of new websites familiar frameworks such as pyramid and libraries are used with computer language. They can be used to integrate protocols such as HTTPS, SSL and FTP and to process e-mails, XML and JSON. The language is also suitable if you want to read out huge amounts of data from the Internet and use it for certain purposes such as price comparisons (Web scraping). Among other things, the BeautifulSoup library is used here. Developers work with the Python code when they interactive games write. For example, they use a 3-D game engine and functionality-providing libraries such as PyGame. Many popular games like Civilization-IV are based on the Python code.

Applicability in business

Applications for the business sector such as shop systems and ERP systems are also based on Python programming. Because these can be read easily, expanded quickly and scaled in next to no time. They are often built on the Tryton platform. In addition, Python is great for Machine learning and AI solutions suitable because it already has a large number of libraries. With the help of Python code, machines can learn from stored information or from previous experience. Python-based algorithms help the machine to learn on its own. Artificial intelligence problems can be solved quickly using the Python libraries and algorithm.

Applicability in data analysis

Anyone who works with the Extraction and analysis of data busy working with Python libraries like NumPy and Pandas. Other collections of data even allow the information collected to be displayed graphically, making it easier to create diagrams. Also in the area computer-aided design (CAD) the language is indispensable. With the help of Fandango, it enables the simultaneous display of functions, objects and much more. In addition, you can Media player program with their help. They are more powerful and stable than other audio and video applications. Professions that typically use computer language include:

  • Data analyst
  • Data engineer
  • Developer in the field of cloud solutions, finance and accounting
  • Engineers in the fields of automotive, mobility service, IoT solutions, IT automation
  • Research Manager (Statistics)
  • Project engineers (rapid prototyping)
  • System administrators
  • Bioinformaticians
  • Data scientist
  • Machine learning engineer

What is it not suitable for?

Despite its many advantages, the language also has some weaknesses. They are manifested, for example, in a too slow execution of the memory cleaning (garbage collection). C ++ and C work better for this because these languages ​​are better adapted to the hardware.

Is Python easy to learn?

If you don't know how to program yet and would like to learn it, you should definitely start with Python. Because of its versatility, however, it also offers many options for advanced and professional users. There are various reasons for learning to program better with the Python code: Because it was developed for beginners in programming, its structure (syntax) is very simple. Unnecessary code was deliberately avoided. Despite its simplicity, it is in no way inferior to competitors such as C ++ and Java: Complex applications can be created with it just as easily as simple plugins. In addition, Python beginners learn other computer languages ​​more easily later on.

How long does it take to learn Python?

How long it takes each newbie to fully master the code depends on various factors. And of course the individual learning pace. In general, the basic knowledge can be learned in a comparatively short time. However, the newbies should be willing to learn for life.

What prior knowledge and requirements do you need for this?

To learn the computer language, you only need knowledge of how to use a Windows PC and basic mathematical knowledge. If the course requires prior knowledge of programming, this is indicated in the course description. The Python software runs on all common operating systems. Linux and OS X already have it as standard.

What are the advantages and disadvantages of Python?

Because of the lean code, the programs written with it run faster. Installation is quick and easy. Errors can be removed with little effort. Working with computer language also saves time: less code has to be written to achieve the desired result. In terms of popularity, it has long since overtaken the competition: the developer platforms are mostly about the Python code. Computer language is also very popular with budding programmers. Because it has a wide range of applications, there are many ideas that you can emulate. If you have any questions or problems, a Google search with the right terms can often help.

But there is another reason for the popular programming language: It will become even more important in the future because of its close connection with AI applications. Web and game developers, data analysts and data scientists will use them to an even greater extent for increasingly complex applications. It is also advantageous that users have many options with it. For example, they create many smaller programs that they use in automated processes such as searching websites and saving the data they find. This saves you from annoying routine activities.

The area of ​​automation is one of the greatest strengths of the language, which offers a large selection in terms of plugins and modules, frameworks and libraries: In addition to the existing standard library, users have access to more than 125,000 external libraries. By the way, they are the reason why computer language is indispensable in so many IT areas. For users who want to work in the field of machine learning and artificial intelligence, the language offers the optimal basis.

Where and how can you learn Python?

If you want to learn the computer language, you have different places and options to choose from. It is of course most convenient to take part in a tutorial offered on the Internet. The paid German-language courses are put together by Python specialists in such a way that the content is easier to learn. They often provide an in-depth introduction. The online tutorial for beginners is available as a video on the home PC and even on the go on the mobile device. It can be paused as needed and played back at a more convenient time.

If you don't learn so quickly, you will repeat the subject matter more often in between. In some tutorials, course participants even receive additional learning material. And as usual with professional courses, a certificate of completion. Complete courses offer, in addition to a comprehensive introduction to the basics of computer language, learning content for advanced learners. With the learning videos, articles, examples from the programmer's practice and the projects to be completed independently, beginners should supposedly master the code after 30 days.

YouTube videos are another way to learn Python programming. However, beginners have to search the platform longer to find the right online course in German. In contrast to the tutorials offered on the web, face-to-face seminars are often only available for expensive money. Fees of more than 1,000 euros per course are not uncommon.

What does a Python code look like?

When writing the Python code, a distinction is made between upper and lower case. Line indents are mandatory. At the end of the line you do not use the sequence “;”. Blocks are formed by indenting the lines, not by using curly braces as in the C languages. Variables do not have to be declared before they can be used for the first time. Assignments are made according to the pattern x = 8. After that, the variable automatically has the value 8. Comparisons are made analogously to the pattern x == 8.

Conclusion

If you want to get into the world of programming, ideally do so with the Python code. And one of the professional web tutorials. So learning succeeds even after a long working day. Due to the very simple and clear code, even beginners will have the opportunity to master the computer language in the foreseeable future.
