A directory is simply defined as a collection of subdirectories and single files; or either one of them. A directory hierarchy is constructed by organizing all the files and subdirectories within a main directory, also known as “root” directory. These subdirectories are separated using a “/” operator in a directory hierarchy. Since the directory is organized in the form of a hierarchy/tree, scanning it can be likened to traversing a tree. And to do that, there are various ways. Using os.walk() method Using glob.glob() method Using os.listdir() method The directories are handled by the operating system; therefore, whenever ...

As a Python coder, you may often come across scenarios where you need to access the user's home directory to perform specific operations like reading or writing user−specific files, configuration files, or data. However, the location of the home directory can change across different operating systems, making it a challenge to access it in a platform−independent manner. In this extensive article, we will explore various methods to obtain the home directory in Python effectively and efficiently. We will proceed to provide step−by−step explanations and code examples to understand the process. Whether you're developing a cross−platform application or simply need to ... Read More

Directory creation is a common task for computer users. You might need to create a directory to store some files, or to place some new files inside an existing directory. In this article, you will learn how to find if a directory already exists in Python or not. A directory is a file system structure used by operating systems and software applications to organize files. It can also refer to a list of files and folders, like the current folder in Windows Explorer. Sometimes there arises a need to check whether a certain directory exists in a system or not; ...

In Python, there are two ways to provide input information to a program. One in which we directly assign input objects to object references/variables; and the other in which the program takes user input dynamically (during runtime). Python 2.x versions use raw_input() function to take user input dynamically; whereas, Python 3.x versions use input() function. The input() function only takes input values in the form of strings, by default. In this article, we will learn how to read the input as “Numbers” in Python 3.x using input() function. Reading Inputs as Numbers Python, like any other programming languages, accepts two ... Read More

Python is a high level programming language that helps a user to run a program and integrate systems more efficiently; as it executes a program in comparatively fewer lines of code. In this programming language, a code can be run in two ways− Interactive mode, and Script mode In this article, we will learn how to execute a python code in a script mode. Python in Script Mode A script mode in Programming languages is nothing but putting all the lines of code in a python program into a file, also known as a script, and ... Read More

Python is a high level programming language that helps a user to run a program and integrate systems more efficiently; as it executes a program in comparatively fewer lines of code. In this programming language, a code can be run in two ways − Interactive mode, and Script mode Note − To run a python code interactively, we use the command prompt in Windows, terminal in Linux and macOS, etc. In this article, we will learn how to execute a python code in interactive mode in Windows. However, the commands are almost same in other operating ... Read More

Command line is the place where executable commands are given to operating system. A Python script can be executed by writing its name in front of python executable in the command line. C:\users\acer>python test.py If you want some data elements to be passed to Python script for its processing, these elements are written as space delimited values in continuation to name of script. This list of space delimited values is called command line arguments. For example, C:\users\acer>python test.py Hello TutorialsPoint When there exists a way to pass arguments through the command line, there must also exist a way ... Read More
