libxml2 is an open-source XML parsing library which is written in C language and provides all the tools needed to read, parse, modify, validate, and write XML and HTML documents. Installing libxml2 Working with XML data in Python requires parsing libraries. One of the most widely used library for this purpose is libxml2. It is an XML toolkit implemented in C, originally developed for the GNOME project. Python doesn't include libxml2 bindings by default, the most common way to work with libxml2 is through the lxml package. Installing it on macOS is quite challenging. This article tells you about to ... Read More

What is Root Access? Root access refers to the highest level of administrative privileges on Unix-like operating systems [Linus or macOS]. This root user has the ability to access all the files and system settings. This includes installing and removing software, altering system configurations, and managing user accounts. Installing Python Modules without Root Access In Python modules are files with the “. py” extension containing Python code that can be imported inside another Python Modules Operations Program. If you don't have sufficient permissions to install Python modules directly on your machines, there are a few alternative methods you can use. ... Read More

What is a Python Module? A module in Python is a simple .py file that contains code, which includes functions, classes, and variables. The module can be reused in other programs. Also, Python comes with built-in modules, which include os and math. Usually, modules are imported statically at the top of the code, but there can also be cases that require dynamic importing. Some of the reasons might be − You are not sure which module to import until the program runs. You are building plugin systems(a software program that allows ... Read More

Installing Python Modules on Mac Managing Python packages efficiently is important for developers; this can be challenging, especially while working on macOS. In this article, there will be a list of different options to install Python modules on a Mac from which you could choose one that is reliable and easy to use. Some common ways to install Python modules in macOS are listed below - Using EasyInstall Using Pip Using Homebrew Using Virtual Environment Using EasyInstall The most popular way to ... Read More

Organizing Python modules efficiently is important to maintain scalability and collaboration. Following best practices can make your project easier to understand and use. In this article, we will discuss about an structure approach to organize Python modules with a sample project and some of the best practices to organize. Sample Project Structure Samplemod is an example of a well-structured project that focuses on creating sample module. Below is the directory structure of this project - README.rst LICENSE setup.py requirements.txt sample/__init__.py sample/core.py sample/helpers.py docs/conf.py docs/index.rst tests/test_basic.py tests/test_advanced.py Let's look at these one by one - ...

Python introduces new features with every latest version. Therefore, to check what version is currently being used we need a way to retrieve them. If a user implements features without the correct version, it can generate random issues. We can check the version using few different methods. These methods are discussed below. Using the Sys Module Using sys module, we can retrieve the current python module version. The following lines of code can be used to do so. import sys print(sys.version) Output The output obtained is as follows. 3.10.6 (main, Mar 10 2023, 10:55:28) [GCC 11.3.0] ... Read More

Python has a capability that allows you to build and store classes and functions for later usage. A module is the name of the file that has these collections of methods and classes. A module may contain more modules. Let’s consider the following example to import multiple modules at once − import sys, os, math, datetime print ('The modules are imported') This imports all four of the following modules at once: datetime(to manipulate dates as date objects), math(consists of functions that can calculate different trigonometric ratios for a given angle), sys (for regular expressions), and os (for operating ...

You cannot, in general encapsulate Python modules in a single file. Because doing so would destroy the module searching method that python uses (files and directories). If you are not able to install modules on a machine(due to not having enough permissions), you could use either virtualenv or save the module files in another directory and use the following code to allow Python to search for modules in the given module:>>> import os, sys >>> file_path = 'AdditionalModules/' >>> sys.path.append(os.path.dirname(file_path)) >>> # Now python also searches AdditionalModules folder for importing modules as we have set it on the PYTHONPATH.You can ...

While installing cygwin, make sure you install the python/python-setuptools from the list. This will install "easy_install" package. Once you have easy_install, you can use it to install pip. Type the following command:$ easy_install-a.b pipYou must replace a.b with your python version which can be 2.7 or 3.4 or whatever else. Now you can use pip to install the module you want. For example, To install the latest version of "SomeProject":$ pip install 'SomeProject'To install a specific version:$ pip install 'SomeProject==1.4'To install greater than or equal to one version and less than another:$ pip install 'SomeProject>=1,Read More

Here is a sample project that shows a very good way to structure your projects: https://github.com/kennethreitz/samplemod The project is about creating the "sample" module. The directory structure looks as follows:README.rst LICENSE setup.py requirements.txt sample/__init__.py sample/core.py sample/helpers.py docs/conf.py docs/index.rst tests/test_basic.py tests/test_advanced.pyThe README.rst file: This file is for giving a brief description of the module, how to set it up, how to use it, etc.LICENSE: Contains license text and any copyright claims.setup.py: It is Python's answer to a multi-platform installer and makes file. If you’re familiar with command-line installations, then make && make install translates to python setup.py build && python setup.py ... Read More
