What Is Python Programming?
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. 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.
Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn't catch the exception, the interpreter prints a stack trace. A source-level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python's introspective power. On the other hand, often the quickest way to debug a program is to add a few print statements to the source: the fast edit-test-debug cycle makes this simple approach very effective.
Python is commonly used for developing websites and software, task automation, data analysis, and data visualization. Since it’s relatively easy to learn, Python has been adopted by many non-programmers such as accountants and scientists, for a variety of everyday tasks, like organizing finances. Python has become a staple in data science, allowing data analysts and other professionals to use the language to conduct complex statistical calculations, create data visualizations, build machine learning algorithms, manipulate and analyze data, and complete other data-related tasks.
Python can build a wide range of different data visualizations, like line and bar graphs, pie charts, histograms, and 3D plots. Python also has a number of libraries that enable coders to write programs for data analysis and machine learning more quickly and efficiently, like TensorFlow and Keras.
Learning the basics of Python can take anywhere from a few weeks to a few months, depending on what you want to learn and how frequently you learn. But since Python has so many uses—and tools to support those uses—you can spend years learning its different applications. Knowing what tasks you want to accomplish and whether you want to use Python in a professional capacity can determine how long your Python journey will be.
Before you start, you will need Python on your computer. Check whether you already have an up to date version of Python installed by entering python in a command line window. If you see a response from a Python interpreter it will include a version number in its initial display. Generally any Python 3.x version will do, as Python makes every attempt to maintain backwards compatibility within major Python versions. Python 2.x and Python 3.x are intentionally not fully compatible. If python starts a Python 2.x interpreter, try entering python3 and see if an up to date version is already installed.
On Windows, try py first - this is the relatively recent Python Launcher, which has a better chance of avoiding some of the path problems that might occur because on Windows programs don't install into any of the small set of common locations that are searched by default. The Python launcher can also let you select any of the various versions you may have installed from a single command.
If you need to install Python, you may as well download the most recent stable version. This is the one with the highest number that isn't marked as an alpha or beta release. Please see the Python downloads page for the most up to date versions of Python. They are available via the yellow download buttons on that page.
The most stable Windows downloads are available from the Python for Windows page. On Windows you have a choice between 32-bit (labeled x86) and and 64-bit (labeled x86-64) versions, and several flavors of installer for each. The Python core team thinks there should be a default you don't have to stop and think about, so the yellow download button on the main download page gets you the "x86 executable installer" choice. This is actually a fine choice: you don't need the 64-bit version even if you have 64-bit Windows, the 32-bit Python will work just fine.
If you're running Windows XP: a complete guide to installing ActivePython is at Python on XP: 7 Minutes To "Hello World!". ShowMeDo has two videos for downloading, installing and getting started with Python on a Windows XP machine - this series talks you through the Python, ActivePython and SciPy distributions. Note that the python.org releases only support versions of Windows that are supported by Microsoft (at the time of the release), so no recent release from python.org can be used on WIndows XP.
See the Python for Mac OS X page. MacOS from 10.2 (Jaguar) to 10.15 (Catalina) includes a system version of Python 2, but it is best not to consider this the Python to use for your programming tasks - install a current Python 3.x version instead. MacOS after 10.15 (Catalina) will not include a default system Python.

Is Python developer a good career?
There are several reasons and based on those reasons it can be said that python developers are a good career to choose from, in the below section I have discussed all the reasons in detail. So, read the points here-
The first benefit of becoming a python developer is that you will get the job very easily because over some time python has developed as a programming language and it is almost used in every IT sector or every company. And according to some statistics python and java are the two best programming language which provides maximum numbers of jobs. So, as a Python programmer, you will get lots of opportunities for jobs.
If you ask any developer or any programmer which is the easiest programming language to learn then everyone should say that it is Python because its syntax is really easy. Besides the easy syntax, there were lots of frameworks are there which makes the tasks easier for the developers. For every works some types of frameworks is present in this language such as for developing app Kivy framework is used, for web development, Django and Flasks are mostly used, for machine learning Tensorflow are considered as a very good framework, and for data science, web2py, cherryPy, Bottle are considered as a very good framework. So, as a python developer you can use these frameworks and these frameworks Will reduce work when you will performing these tasks.
The Salary package is a really major and crucial factor before choosing a perfect career. Because your career is all about passion and money. Well, if your passion is computer programming and if you learn python then you can earn lots of money from this field. This language is totally in demand and on average, a python developer almost earns 5,00,000 rupees per annum in India. While, in developing countries, python developers earn much more money as in the united states python developer’s salary is $75,000 per autumn, while in the UK these developers earn almost 72,000$ per autumn which is fairly considered as a very good amount.
Freelancing is another very good option for the python developer to earn money. If you have some expertise in this python programming field then you can earn a huge amount, because lots of freelancing works are available on the freelancing platforms and there were not many python developers who can do these works. There were several freelancing platforms are available such as Upwork, Fiverr, freelancer, you just have to visit these platforms and create an account and bid for work.
When you are choosing any programming language you have to choose it perfectly because according to Wikipedia there were almost 700+ programming languages are available and if any programming language is unable to update its features then the other languages can take its place.
Suppose if you have selects the c programming language and in recent times no works can be done with c programming and therefore it is not good for the future. But, that is not the case with Python, because it is a very good programming language and the future demand for this programming language is high, so python developer is also a good career to choose for the future.
As a python developer, you can utilize your skills in diverse fields, here I want to say that if you have learned python programming then you can go for machine learning, artificial intelligence, data science, web development, and other areas.
These are some of the major reasons why python developer is a good career.
Skills Required to Become a Python Developer?
Although, there are numerous languages are available in the market but python has become one of the most emerging programming languages in recent time. It can be used in several places and if you want to become a developer then you have to choose the better language which suitable for your work. As python becomes a very popular and demandable language, therefore most programmers want to build their career and learn Python Programming but they don’t actualize how to start and learn Python so in this article I am going to discuss how to become a Python developer.
So, how to become a Python developer? it completely depends on you about how you want to learn this language. This language is a very easy programming language for beginners and the syntax of this language is easier than the other languages. All you can do, you can make or create any roadmap to learn python, otherwise, you can also take some courses about Python programming.
As a Python Programmer, the first thing you have to do is to learn the Python basics concepts very well. So there are three stages of learning python- beginner stage, intermediate stage, advanced stage. Always starts from the beginning, and at first learn the concepts of variables, numbers, strings, primitive data types, etc.
After that, you can learn a little bit about advanced data types such as dictionaries and tuples, functions, modules, etc.
Once you have clear the concepts of basics then go for intermediate skills. As an intermediate Python Programmer, you have to learn the concepts of exception handling, classes, object inheritance, iterators, generators, lists, sets, command lines, etc.
Once you have learned the intermediate skills then you have to learn about the advanced Python skills and you have to use the multiprocessing and multithreading, decorators concepts, multiprocessing lock, and pool, and context manager skills.
This is the first step to become an expert python developer, now you can move to the next topic which is data structures and algorithms.
Data Structures and Algorithms:
If you want to learn any programming language then the data structures and algorithms concepts are a must for you. If you know good data structure concepts then it allows you to write the code more efficiently. Without these concepts, you can write programs but these programs do not work efficiently. And later it will become much more difficult for you to maintain that code.
Being a web developer I have worked with many Python developers and one common thing I have found in them is their debugging skills. If you have good debugger skills and your codes are not behaving properly then you can easily resolve this problem.
Using Libraries properly:
One of the major things of Python becoming the most popular language, because of its libraries. Python consists of several programming languages which will make easy your work as a Python programmer. For example NumPy, it is a numeric computing library which allows you to do multidimensional arrays, type of manipulations, and if you don’t know about this NumPy library then can not do these things efficiently. You can use pandas for data cleaning and data analysis. For scientific computing, you can use SymPy and other libraries. You just have to search about python libraries and you have to use these libraries wisely.
PEP8 & Coding Best Practice:
As a good python programmer, you have to write readable python code and for this purpose, you can use the PEP8.
Open Souce contribution and Code Reviews:
Many types of people argue that we do not know Python and how we will contribute to open-source python code. But you can contribute to open source even by modifying the documentation.
When you will open source you have the chance to interact with the experts and during the code review process, they will give you lots of useful commands, which will make your coding much better.
This is the last point and according to me the most essential point, as a Python programmer you have to practice lots of projects. You just have to visit Google or GitHub or stack overflow and you have to search for the projects. And from here you have to resolve the projects and once you will be able to handle those projects or solve those projects then your Python skills become much better. This is the whole roadmap to become a good Python or an expert Python developer. If you learn all the skills that I have mention in a step-by-step process then you can achieve expertise in python programming.
Which Python Framework Should I Learn in 2021?
We know that frameworks make the tasks easy for the developers. And therefore it has become mandatory to learn frameworks. A similar case is with Python, if you want to become a good Python developer then you have to learn some of the frameworks.
In the Python programming language with the help of frameworks, you can efficiently implement the codes. The readability of the codes becomes very good. And you can reuse the code several times. Besides that, the maintenance of the code is also a good factor in the Python programming language.
