When we are working with files in Python we may need to copy only a certain type of file. Python makes this task simple and flexible by using built-in modules such as os and shutil and pathlib. Copying specific files using shutil and os modules When we want to copy only certain files such as all .txt files from one folder to another in Python then we can use the shutil and os modules. The shutil module is used to perform high-level operations on files such as file copying, moving, archiving and removing directories whereas os module is used to ... 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

This tutorial looks at various Python comparison techniques for two files. We'll go over how to perform this typical work by using the available modules, reading two files, and comparing them line by line. In Python, comparing two files can be done in a variety of ways. Comparing Two Text Files Line by Line Using the open() function to read the data from two text files, we can compare the information they contain. The local directory will be searched for and potentially read by the open() function. Example We'll contrast two files containing python data in this example. We're informed ... Read More

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

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
