Comprehensive Guide to Python

Why should you learn Python?

Learning Python is essential for various reasons. For those studying Computer Science, the term Python Programming or Python Language is likely familiar. However, it is important to note that programming skills are also necessary in numerous other academic disciplines beyond Computer Science and Computer Engineering. Although programming can be done with any language, programming with Python is more popular than the other ten languages. If you want to know more about Python language, you must read the entire article.

What is Python?

Python is an advanced programming language that operates at a high level. It is employed to address a wide range of challenges on computers, to develop diverse systems, to create applications for multiple devices, and to offer services to users. Python’s syntax is close to human language. Because of it’s language-level . That is, any programmer can easily understand and write the Python language just by reading it.

Named Python came from

In 1991, a Dutch man named Guido Van Rossum named his own programming language Python, inspired by a comedy series called Monty Python’s Flying Circus.

What type of programming language is Python?

Programming languages are generally of two types. Interpreted Language and Compiled Language. Python is an interpreted language. Compiled languages compile the entire source code and then execute it. For example, Java, C++. On the otherhand, interpreted languages execute only one line at a time. And this is Python.

Why is Python so popular?

If I going to run a programme with java and c# it will 10 hours, but if I run it with python, then it takes only 2 hours. Are you surprised? There are many reasons for this. Python’s syntax is very short. And big work is done with this small syntax. And the libraries provide such good support that big output can be obtained by writing small programs. Those who have worked with data analysis have benefited the most by using this Python language. Python is also used in web & software in build.

Difference between Python language and Python programming?

I said, yksi, kaksi, kolme, nelja, (one, two, three, four) in Finnish. Another said one, two, three, four in English and another said it in their own mother tongue. The basic elements here are the same, only the language is different. To create a system or software using a computer, you have to do programming. You can write this programming in any language of your choice or suitable for the system. The basic element here is your system. Now if I create this system with Python language, that is, if I write the programs with Python language, then it will be Python programming. I hope you understand the difference between language and programming.

Various sector is Python being used?

• System Scripts and Automation:

Python was originally created for back-end development. As scripting becomes more popular, Python’s popularity grows. Python scripts save a lot of time compared to scripts in complex languages. Today, Python automation is being used in everything from web searches to content downloads, online forms, and email sending. It is used in ethical hacking.

• Web and App Development:

Python is a one fo the famus programing language for web developers. Sites like Google, Instagram, and Reddit have been built using Python. The web frameworks on which software is created using Python are Django and Flask. Python has a simple connection with web development, so any website can be created very easily using Django.

• Scientific Computing and Data Analysis:

Astronomers, biologists, neuroscientists all use Python. In addition, large corporation like CERN and NASA use Python. It has been possible due to the enthusiastic community of Python. Apart from this, there are also data manipulation tools like pandas, PsychoPy for experimental psychology. The data collected with Python can be easily scaled. That’s why it is too easy to work with.

• Machine Learning and Artificial Intelligence:

In today’s era, the world would almost come to a standstill without these two things. Basically, they are well intertwined with financial matters. Starting from voice, image recognition to Netflix’s algorithms. There are uses in all fields. New York Stock Exchange created using Python. Like all other libraries, there is a huge library of Python here too. TensorFlow is a high-level neural network library. The scope of Python in artificial intelligence will continue to grow.

• Game Development:

For a long time, game developers have been creating GUI (Graphical User Interface) applications with Python. Python has many 3D animation packages. It is used in computer games and special effects. Games are created with the help of PyGame, PySoy, Pykara libraries. In addition, Python has also been used in the special effects of recent Marvel movies. This shows that once you become proficient in Python, you don’t have to worry about jobs. And there is freelancing.

Advantages of Python programming language

Python’s syntax is small• You can easily understand what has been programmed by reading the syntax• The same source code works on all platforms• It is very easy to program by casting data types• Python is an open source language• Because of the large number of libraries and built-in functions, large programs can be completed with little programming• If there is a mistake, debugging can be done easily

Disadvantages of Python programming language

It is not a fast language like C, C++, the program takes time to run• Although Kivy is available for making mobile applications, good quality apps cannot be made• Excessive memory is consumed. Therefore, optimization has to be done while creating programs• A lot of investment is required to create a system with Python language

Some of Python’s popular frameworks–

Django and Flask are two famus frameworks for web built. Flask is used for small tasks. And Django framework is used for large application development. There are also full stack frameworks like Bottle, CherryPy, Web2Py, Pyramid, Hug. There is Kivy for creating mobile applications. But Python is not of very good quality for mobile apps. There are wxPython, Kivy, Bottle, PyQT, Tkinter, for creating desktop applications.

Some popular Python libraries–

Some popular libraries for working with datsa cience, machine learning, artificial intelligence, Numpy, Scipy,   image processing are TensorFlow,  Keras, Pandas, Pillow, Scikit-Learn, etc.

Careers with Python Language in Finland–

Above, you have learned which popular websites or applications are currently using Python. But when it comes to Finland, software companies that offer jobs with Python are only just starting to emerge. Although there are not many jobs like other languages, the use of Python is gradually increasing. So you can understand that the use of other programming languages ​​is gradually decreasing in Finland. If you enter various job websites in the country and search for Django, you will understand how much salary is being paid in Python language. Not only jobs, you can also do freelancing with Python if you want. You won’t even earn $2 just by learning Python and Django. Along with these, you have to learn any one framework among Database, JavaScript, React/Vue.

Should you learn Python or do problem solving?

It doesn’t matter that, your’re skilled in Python, but, you can’t solve a problem, then, you won’t get any job. Because, during the interview, you will be asked many basic questions. Like, algorithms, structures, etc. So, improve your skills by solving more and more problems so that your performance is ahead of other programmers. There are popular online judges like Beecrowd, Hackerrank, Codingbat, etc. for problem solving.
