What is machine learning and why is it so great?
Machine learning is the modern science of finding patterns and making predictions from data based on work in multivariate statistics, data mining, pattern recognition and advanced/predictive analytics and is a subset of artificial intelligence and again intersects with many disciplines including mathematics. and psychology.
Machine learning may sound futuristic, but it’s not. Speech recognition systems like Cortana or Search in e-commerce systems have already shown us the benefits and challenges that go hand in hand with these systems. In our machine learning series, we’ve introduced you to several tools that make all of this possible.
Reasons why it’s so cool A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023:
The power of a well-built machine learning approach to a problem far exceeds that of a (human) individual and even a team.
It removes any psychological biases in data analysis.
The more data (and time) you give it, the stronger it becomes.

As a beginner, you can start with Python and move on to other languages once you get the hang of it. Python is one of the most flexible languages and can be used for a variety of purposes A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Python gained huge popularity with this. Python includes special libraries for machine learning, namely scipy and numpy, which are great for linear algebra and getting to know the kernel of machine learning.
The language is great for working with machine learning algorithms and has a relatively easy syntax. For beginners, it is the best language to use and to start with.
If this is your very first exposure to programming through machine learning, you can choose Codec Networks is Best for Python Training in Delhi as the best option, due to its wealth of libraries and ease of use.
It can still be quite useful if you dream of a job on the other hand. Whatever the case, these are exciting times for machine learning, and the journey is guaranteed to be overwhelming, no matter which language you choose. Enjoy the ride!
If you’ve ever wanted to simplify command-line scripting or use Python alongside command-line applications—or any other applications—then the Python threading module can help. Python’s subprocess module can help from running shell commands and command-line applications to running GUI applications A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
At the end of this tutorial you will be able to:
Understand how Python’s thread engine interacts with the operating system A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023
Issue shell commands like ls or dir
Enter a process and use its output.
Handle errors when using a thread
Understand use cases for threading by considering practical examples
In this tutorial, you’ll get a high-level mental model for understanding processes, threads, and Python before getting stuck into the threading module and experimenting with an example. You will then begin to explore the shell and learn how you can use the Python thread with Windows and UNIX-based shells and systems. Specifically, you will deal with communication with processes, channels and error handling A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Note: Subprocess is not a GUI automation module or a way to achieve concurrency. For GUI automation, you might want to check out PyAutoGUI. For concurrency, see the Thread Related Modules section of this tutorial A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Once you’ve got the basics down, you’ll explore some practical ideas for using the Python thread. You’ll also dive into advanced Python threading by experimenting with the basic Popen() constructor A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.

Processes and subprocesses
First, you might be wondering why there is thread in the name of the Python thread module. And what exactly is the process? In this section you will answer these questions. You get a high-level mental model for thinking about processes. If you’re already familiar with processes, you may want to skip straight to the basic use of Python’s threads module A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Processes and Operating System
Whenever you use a computer, you will always be working with programs. A process is an operating system abstraction of a running program. So using a computer always involves processes. Start menus, application panels, command line interpreters, text editors, browsers, and more—every application contains one or more processes.
A typical operating system will report hundreds or even thousands of running processes that you will soon be able to investigate. However, central processing units (CPUs) typically have only a few cores, which means they can only execute a few instructions at a time. So you might be wondering how thousands of processes can appear to be running at the same time.
In short, the operating system is an amazing multitasker – as it should be. The CPU is the brain of the computer, but it operates on a time scale of nanoseconds. Most other computer components are much slower than the CPU. For example, reading a magnetic hard disk takes thousands of times longer than a typical CPU operation.
If a process needs to write something to the hard disk or wait for a response from a remote server, then the CPU will sit idle most of the time. Multitasking keeps the CPU busy A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Part of what makes the OS so great at multitasking is that it’s also fantastically organized. The operating system keeps track of processes in the process table or process control block. In this table, you will find the process’s file descriptors, security context, references to its address spaces, and more.
The process table allows the operating system to exit a particular process at will because it has all the information it needs to come back and resume the process later. A process may be interrupted many times during execution, but the operating system always returns to find the exact point where it left off.
However, the operating system does not start with thousands of processes. Many of the processes you are familiar with have been started by you. In the next section, you will look at the lifetime of the process.
Think about how you could run a Python application from the command line. This is an instance of your command line process that starts a Python process A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023:
Animation of creation of basic processes
A process that starts another process is called a parent, and the new process is called a child. The parent and child process run mostly independently. Sometimes a child inherits specific resources or contexts from a parent.
As you learned in Processes and the Operating System, information about processes is stored in a table. Each process keeps track of its parents, allowing the process hierarchy to be represented as a tree. In the next section, you will explore your system’s process tree A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
Note: The exact process creation mechanism varies depending on the operating system. For a quick overview, the Wikipedia article on process control has a short section on creating processes A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
For more details on the Windows mechanism, see the win32 API documentation page on process creation
On UNIX-based systems, processes are typically created by using fork() to copy the current process and then replacing the child process with one of the exec() family functions.
The parent-child relationship between a process and its subprocess is not always the same.
Sometimes the two processes will share specific resources such as inputs and outputs, but sometimes they won’t. Sometimes child processes live longer than parents. A child surviving a parent can lead to orphaned or zombie processes, although further discussion of these is beyond the scope of this course.
When a process finishes, it usually finishes. Each process should return an integer on exit. This integer is referred to as the return code or return status. Zero is synonymous with success, while any other value is considered a failure. Various integers can be used to indicate the reason why the process failed A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
In the same way that you can return a value from a function in Python, the operating system expects an integer return value from the process once the process has finished. This is why the canonical C main() function usually returns an integer:
/This example shows the minimum amount of C code needed to compile a file with gcc without any warnings. It has a main() function that returns an integer. When this program is run, the operating system will interpret its execution as successful because it will return zero A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
So what processes are currently running on your system? In the next section, you’ll explore some tools you can use to look into your system’s process tree. The ability to see what processes are running and how they are structured will come in handy when visualizing how the thread module A CHAIN REACTOR TOWARDS A BRIGHTER FUTURE ITS PYTHON 2023.
