P_01: Introduction to Python Programming | Python for Beginners

Python is currently the most popular programming language, and it is also the fastest growing programming language. The concept of Python was introduced in 1989, and it has become widely used in areas such as machine learning, data science, and artificial intelligence. One of the reasons Python has become so popular is because it is easy to learn and understand, and it has a wide range of applications. It can be used in almost every area, and many big companies use it as a main or supportive language. Python is a multiparadigm language, and it is a general purpose language, which means it can be used to create almost anything. Python is an interpreted language, which means it is not compiled, and it is open source. This is why it has a huge community and a rich library of inbuilt packages, modules, and functions.

Python is a language that offers a plethora of career opportunities in various fields. Its popularity is mainly attributed to the high average salary range of 8 to 12 per nm, which makes it an attractive language to learn.Python's application areas are diverse, making it a versatile language to work with. Some features of Python are particularly useful in specific fields, making it an ideal language to use in these industries.In the upcoming video, we will delve into the history of this language before we go into more detail about its features and application areas.

Jonathan gardener talks about the concepts in computer science as well as software engineering as a practical career. This video is part of his theory of Python video series where I cover the Python language in detail. We'll talk a lot in detail about what a function is in Python what that means in programming languages. We worry a lot about VM's virtual machines Java Python Python c-sharp all use virtual machines. The other thing that we have to think is the type system and this gets into the data structure how do you organize your data structure. Python does n't do JIT compiling but pi PI which is an alternative implementation of Python does we 'll talk more about pi PI later. There are many different kinds of type systems and people try to boil this down to like there is this type of program rate this is this kind of type system it's nonsense there 's many vectors one of the most important aspects is dynamic versus static in a dynamic type system the variables that you use in the program can refer to any type variable any type of value. The variable name as associated with it the type of the object you 're looking at right.

Python itself kind of started off as a joke and then it became useful and people recognize its value and so it basically advertised itself by word of mouth. Python is the kind of language you want to see other things that affect popular dairy is you might have free languages or free programs versus free software free software is not necessarily free. Programming languages are important it 's important you choose the right programming language with a job if you do n't know what language that is the answer is Python for most jobs there are some cases where I would not recommend Python there is a huge difference that I found between Java and Python and my experience I estimate that I was basic about 10 times is fast with Python and Java. Python white Python is simple it 's simple and easy you can master the language breath rather readily and also it allows lots of flexibility so they 'll be able to learn and explore lots of different concepts that 's why I 'm starting this video series on the theory of Python and not Prolog

python is nowadays the most popular programming language but you can say it is the fastest growing programming language nowadays. The concept of python came into picture in 1989 and even java was you know the concept of java or python i 'll pronounce it as python right okay now see python is being used right now the main areas are machine learning data science artificial intelligence. White has become so popular because first thing is it is easy to learn easy to understand and it has wide range of applications i have told you in how many areas almost in every area it 's been used in almost every area. The big giants companies are using this language maybe the main language or supportive type of language as a support language. python is multi-paradigm language it is general purpose language almost in every field for making everything you can use this language. python is interpreted language without compiled language and is open source so that is why it is having a huge community and rich library many ill you know inbuilt packages modules functions.

The main areas where Python is being used are in software development, web development, data science,, artificial intelligence,, game development, and mobile apps..NK] Big giants companies are using Python as a support language in their research and development fields.. [UNK] is an easy to-understand, relatively low-level language that is suited for data analysis, software, development,, and game programming..NK] also has a wide range of applications in fields like artificial intelligence and machine learning.. 1.. Python is a general purpose, interpreted language. 2.. Python has a rich library with many preexisting functions and modules that can be used in programs without having to write them from scratch. 3.. Python is a popular language for data science and machine learning due to its built-in libraries and modules.. 4. Python has a large community of developers who can answer questions and help you out if you are struggling with using. It.

There are lots of career opportunities for this in this field for this language. There are many career opportunities and average salary is also high like it 's from 8 to 12 per nm so that is why it is so popular and i'm sure you are aware about now this language some features who are using it the application areas of python and all. In the next video we will see history of this language first.
