In file system management, it's sometimes necessary to update the modification or access time of files which is commonly referred as "touching" files. This is useful in automation scripts, build systems or cache invalidation mechanisms. Python offers powerful modules such as os and pathlib to touch all files within a directory recursively. In this article, we'll explore different methods to recursively touch files using Python by ensuring each file's timestamp is refreshed as needed. Using os.walk() and os.utime() The os.walk() function generates the file names in a directory tree by walking the tree either top-down approach or bottom-up approach. It ... Read More

Zipping a folder recursively means compressing a folder along with all its subfolders and files. In this article, we will explore all the possible ways to zip a folder recursively using Python. Using zipfile and os.walk() In Python, we have the methods zipfile() and os.walk() to zip all the folders recursively. This is a manual approach of zipping the available subfolders and files into one. Following is an example that shows how to zip a folder recursively using Python - import zipfile import os def zip_folder_manual(folder_path, zip_path): with zipfile.ZipFile(zip_path, 'w', zipfile.ZIP_DEFLATED) as zipf: ...

In Python, pip is a standard tool which is used to install third-party packages in our system. By default, pip installs packages into the site-packages directory of the current Python environment but in some cases, such as restricted environments or creating portable apps, we may need to install packages into a different directory. Then we can use the pip's --target option. Syntax Following is the syntax of using the pip command while installing a python package in a different directory - pip install --target The above command tells pip to install the specified package and all its ...

In Python, we can extract a specific part of a file path of the directory using built-in modules such os.path and pathlib. Extracting a part of the file path is commonly needed when working with file systems, data processing, or scripts that handle files dynamically. Using os.path Module The os.path module in Python provides functions to manipulate files and directory paths. We can use this module to extract directory names, file names, and traverse up directory levels. Example Following is an example, which shows how to use the os.path module to extract a directory path from a full file path ... Read More

Iterating over files in a given directory helps to perform tasks such as finding files that match certain criteria or, counting the number of files in a directory. Python provides the following five ways to walk through all the existing files in a directory - os.listdir() method os.walk() method os.scandir() method Using pathlib module glob.iglob() method In this article, we are going to see all the above methods that are used to iterate over files in a given ...

The given task is to list the directory tree structure, i.e., we need to print the hierarchy of folders and files starting from a specified root directory. This is similar to how the tree command works in Linux or Windows by showing nested folders and files in a structured and indented format. In this article, we will see all the possible methods in Python to list the directory tree structure. Using os.walk() Method The os.walk() method in Python is used to generate the file names and folder names in a directory tree by parsing through the tree in either a ... Read More

In Python, when we are working with directory structures, it is necessary to check whether a given directory contains any other directories within it or not. This process of checking is useful when performing batch operations, cleaning up folders, or traversing file systems. Python provides several built-in ways to perform this check effectively. In this article, we will go through different methods using both os and pathlib modules to determine if a directory contains any subdirectories. Using os.listdir() and os.path.isdir() The os.listdir() method is the straightforward method to detect subdirectories to list directory contents, and when it is combined with ... Read More

When we are dealing with large directories, managing files and folders is often required in listing them in a specific order. One common approach to list out the files/folders is sorting items by their names, which makes navigation and processing much easier. Python simplifies this task with built-in modules such as os and pathlib, which allow developers to fetch and organize directory contents with just a few lines of code. In this article, we will go through the different methods to retrieve and sort directory listings alphabetically with clean and flexible solutions for our file-handling needs. Using os.listdir() with sorted() ... Read More

When working with files in Python, it's often useful to sort them based on their creation time. For example, to find the most recently added file or to process files in the order they were created then we need sort them by the creation date. Python provides built-in methods such as os and os.path which makes it easy to retrieve file metadata and sort directory contents accordingly. In this article, we will explore all the different method to sort the directories based on the creation date in Python - Using os.listdir() with sorted() and os.path.getctime() ... 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
