Python kya hai aur, c python kya hoti hai ?

Further you will know about the history of c python and learn about the basics of source code of c python you will understand the working of c python and know why c python written in c and not python let's start with c python the default implementation of the python programming language is c python and it is one of the python runtimes it is directly downloaded from python.oig in programming language c and it also executes the programming language python let's know about its history so the first version of c python was released in 1994 by the python developer community now let's brush up some basic concepts first one is the python programming language it is a high level general purpose programming language if we talk in general the programming language only describes how to express yourself .

 Interpreter that is the program which accepts the python code the next is implementation it is all about how the interpreter was written specifically in what language and what it ends up doing the next is machine code machine code it is set of instructions that directly gets executed by the cpu almost all the high level languages such as c translate the source code into .

 Executable machine code with the help of compilers loaders and linkers the next concept we'll learn is bytecode bytecode it's the code that is processed by a program usually referred to as a virtual machine rather than the real computer machine and moreover the machine code is much faster as compared to bytecode but bytecode is portable and secure as compared to machine code now let's get to know whether python is interpreted or compiled language we have read that python is an interpreted language but the truth is that it is both compiled and interpreted language before moving ahead let's brush up the concepts of compilation and interpretation first we'll start with compilation it's the process in which the source code is translated into the machine readable code or it serves as the input .

 To another compiler or interpreter it takes whole code file as an input the code is translated once into object code and can be run many times it will not execute the machine readable code it produced the next we'll learn about is interpretation interpretation it's the process that takes a single line of code at a time and executes it interpreter executes the instructions .

 Specified in the source code while the program gets executed now we will see both compilation and interpretation in one diagram many programming languages don't compile to actual machine code but to a byte code the compiler first compiles the source code to an intermediate language called bytecode which is the low level platform independent representation of the source code .

 The virtual machine that is interpreter then takes the byte code and executes it now let's move ahead and see some basic concepts of source code of c python the c python source distribution comes with a whole range of tools libraries and components to compile c python from the source code you need a c compiler and some build tools according to your os to download a copy of the c python source code you can use git to pull the .

 Latest version to a working copy locally now let's understand the working of c python c python ends up producing byte code which is python specific and then it executes it the reason to convert python code to bytecode is because it's easier to implement an interpreter if it's look like machine instructions but it isn't necessary to produce some byte code prior to execution .

 So we will understand this with the help of an example first the compiler receives the source code it then checks the syntax of each line in the source code if the compiler encounters an error it holds the translation process with an error message else if the transaction is well formatted then it translates the python source code into a special low-level intermediary language called bytecode this byte code is stored in dot pyc .

 Files that is hidden in a directory and cached for execution and only understood by c python bytecode is sent to the python virtual machine that is pvm python virtual machine is the part of the python system that actually runs the python code that is in the format of white code it takes the bytecode instructions one by one and executes its section bytecode along with its input and library modules is given as the input to .

 The pvm the is python virtual machine python virtual machine executes the byte code and if any error occurs it displays an error message that would be the runtime error otherwise if there is no error in execution it results in the output now let's see why c python is written in c and not in python as c python follows source to source compiler model these source to source compiler models are first written in another language .

 Which is already possessing a compiler we have a very good example of go language first co-compiler was based on c programming language as when go could be compiled the compiler was rewritten in go with that we have come to the end of this session i hope it was interesting and informative if you liked it please let us know in the comment section below also do subscribe to our channel and stay tuned for more from .

 Although autonomous cars have stormed the market today using data gathering and analytics new technology trends and functionalities like autonomous braking lane changing and automation of other in-car systems are on the way to being streamlined although there are a few shortcomings that are yet to be resolved there's no ruling out the fact that the streets will see more and more of autonomous cars in the near future .

 Tesla audi ford apple waymo kia and other companies are immensely working with making driving completely autonomous intelligent process automation intelligent process automation ipa is the use of artificial intelligence and related emerging technologies to robotic process automation such as computer vision cognitive automation and machine learning according to mckinsey organizations in .

 Several industries that have experimented with intelligent process automation have achieved impressive results with the automation of about 50 to 70 percent of tasks 25 to 30 percent annual cost reduction and roi in triple digit percentages it's safe to say the main benefit of intelligent process automation is the significant amplifications of the returns rpa offers companies like cat gemini deloitte ibm sap etc are reading .

 Deploying intelligent process automation in their organizations with that being said if you wish to create something cool and help make a difference check out simplylearn's postgraduate program in ai and machine learning in partnership with purdue university and in collaboration with ibm it covers topics like machine learning deep learning statistics and nlp among others in conclusion with such big advancements .

 In technology the future looks more promising than ever it is likely to reshape all sectors of life there is simply no stopping it have you heard about the new innovations that have been recently implemented let us know in the comment section below thank you for being here and watch out for more videos from us until then keep learning and stay tuned to simply learn .
