Yes you can keep Python modules in compiled format. Python automatically compiles Python source code when you import a module, so the easiest way to create a PYC file is to import it. If you have a module mymodule.py, just do:>>> import mymoduleto create a mymodule.pyc file in the same directory. A drawback is that it doesn’t only compile the module, it also executes it, which may not be what you want. (however, it does compile the entire script even if it fails to execute the script). To do this programmatically, and without executing the code, you can use the ... Read More

The best and recommended way to install Python modules is to use pip, the Python package manager. It automatically installs dependencies of the module as well.If you have Python 2 >=2.7.9 or Python 3 >=3.4 installed from python.org, you will already have pip and setup tools, but will need to upgrade to the latest version:On Linux or macOS:pip install -U pip setuptoolsOn Windows:python -m pip install -U pip setuptoolsIf you’re using a Python install on Linux that’s managed by the system package manager (e.g "yum", "apt-get" etc…), and you want to use the system package manager to install or upgrade ...

In Python, you can dynamically call a function from a module by using its name as a string. This is useful in scenarios where function names are not known until runtime. Below are several methods to achieve this. Using getattr() Function Using globals() Function Using locals() Function Using importlib Module Using 'getattr()' Function The getattr() function is a built-in Python function that allows you to retrieve an attribute from an object using a string representing the attribute's name.

This module is popularly used to simplify for processing or display of user-generated content and international data [multi-lingual]. Installing Python Unidecode Module To install unidecode or any other Python module, you need pip installed(Python package manager). If you have Python 2 >=2.7.9 or Python 3 ... Read More

No, there isn't a direct equivalent to PHP's autoloader in Python and you don't need one also. To be specific, PHP needs autoloaders for the following reasons - For each web request to start a fresh PHP process. To load all the code from scratch for every request. For optimization by loading classes only when required . To avoid loading unnecessary files which improves performance. In contrast, Python doesn't require autoloaders as files are not reread every time, and if you import ... Read More

What is Python Module? A file containing Python commands and definitions is referred to as a Python module. These files have .py suffix that contains Python code, such as example.py, and the name of the module is an example. Modules are used to divide down huge applications into smaller, more manageable files. As Python projects grow, organizing code becomes essential. One of the most effective way to manage complexity and avoid code re-usage is creating your own Python module. Some of the benefits of creating modules include − Organized Code Re-usability ...

What are Python Modules? Python module is a ".py" file that contains Python definitions, functions, classes, variables, constants, or any other objects. Contents in this file can be re-used in any other program. Packaging in Python Python packaging involves compressing bundles of Python code in a particular format that can be publically shared and can be installed by a tool like pip. Importing Modules To use the functionality present in any module, you need to use the import keyword along with the module name. This keyword will import the module to your current program.

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
