When working with the Python scripts, it is required to interact with user-specific files or directories and also it's essential to accurately determine the actual user's home directory. This is especially important if the script might be executed with elevated privileges like using sudo where default methods could mistakenly point to /root directory instead of the true user's home. Python offers multiple ways to retrieve the home directory and selecting the appropriate method which helps to ensure consistent and expected behavior across different environments and permission levels. In this articlE, we will go through the different methods to find the ... Read More
The Python shutil module provides a number of functions for high-level operations on individual files and file collections. In this article, we will go through different methods of moving a file from one folder to another using Python. Using the OS Module The Python OS module gives users the ability to create interactions with their operating systems. Using shutil.move() method Following is an example which shows how to move a file from one folder to another using shutil.move() method - # importing the modules import shutil import os # Providing the folder path origin = 'C:\Users\Lenovo\Downloads\Works' target = 'C:\Users\Lenovo\Downloads\Work ...

Swap files and temporary files are common byproducts of text editors such as Vim, Emacs or even modern IDEs. These files—often with extensions like .swp, .swo, .tmp or .bak are used to store session data or backup content temporarily. These are useful during editing sessions in which they can clutter our project directories or interfere with version control systems if not cleaned up. In this article, we are going to explore how we can leverage Python to automatically find and delete these unwanted swap files from our workspace. Using os.walk() for Recursive Deletion In this approach we use Python's os.walk() ... Read More
Creating an empty file is a common task in programming when we are initializing log files, setting up placeholders or working with automation scripts. Python provides several easy and flexible methods to create empty files. In this article, we'll go through different ways to create an empty file in Python. Using open() with Write Mode 'w' The open() function is the most straightforward way to create an empty file. When we use the write mode 'w', then it creates a new file if it doesn't exist. Example Following is an example, which shows how to create an empty file using ... Read More
Managing hidden files and folders in a directory is an essential part of building cleanup scripts or automation tools. On Windows, hidden files are not prefixed with a dot but instead they are marked using specific file attributes. In this article, we will explore how to remove those hidden files and directories programatically using Python. Filtering by Dot Prefix (Unix/Linux/macOS) On Unix-based systems, the files or folders starting with a dot "." are considered hidden. We can use this naming pattern to filter and remove hidden files. Here is an example of removing the hidden files and directories present in ... Read More
The site-packages directory in python, is the place where third-party libraries and packages are installed. Knowning the site-packeges location is useful for debugging, verifying installations or inspecting package contents. This directory may vary depending on our operating system, Python version or based on the virtual environment we are using. In this article, we are going to explore the different ways to find the location of site packages directory in our working environments. Using site.getsitepackages() The getsitepackages() function of the site module, returns a list of global site-packages directories. This method may not work inside virtual environments and could be unavailable ... Read More
We can easily check the Odd or Even by using conditional statements. We can divide the number by 2, then check whether the remainder is 0 or not. If 0, then it is even. We can also perform the AND operation with the number and 1. If the answer is 0, then it is even; otherwise odd. There is no need to use conditional statements in both approaches. We will see two different methods to check the odd or even. Using Modulo Operator This approach uses the Modulo Operator ... Read More
A portable method of interacting with the operating system is offered through the OS Python Module. This module is a part of the default Python library, which contains tools for locating and modifying the working directory. When we are working in the Python shell or scripting environment, it's important to know which directory we're currently working in. This is known as the current working directory. We can change the current working directory to navigate our file system programmatically. In this article, we will see how to change the current working directory in the Python shell. Getting the current working directory ... Read More
The auto keyword in C++ is used to automatically determine the type of variables from their initializer. This means you don’t need to explicitly tell the compiler the variable's data type. It lets the compiler determine the variable's type during compile time.C++ auto KeywordAuto was a keyword that C++ "inherited" from C that had been there nearly forever, but virtually never used. All this changed with the introduction of auto to do type deduction from the context in C++11. Before C++ 11, each data type needs to be explicitly declared at compile time, limiting the values of an expression at ... Read More
The extern storage class specifier lets you declare objects that several source files can use.What is Extern Storage Class in C++?The extern storage class in C++ is used to declare an object (global variable or function) that can be accessed by multiple source files. When a variable is declared with extern, it tells the compiler that the variable or function exists in another file (or later in the same file) and that memory is not allocated at the point of declaration. Syntax Here is the following syntax for the extern storage class in C++. Here, it's a declaration, but no ... Read More
