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 ...

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

A file containing Python code, definitions of statements, functions, or classes is known as a module. A module with the name "module" that we will construct is a file named module.py. To break down complex programmes into smaller, easier-to-understand parts, we use modules. Code reuse is another benefit of modules. In this article, we will discuss various ways to find which Python modules are being imported from a package. Using List Comprehension To iterate over each element in the Python list, a list comprehension is made out of brackets carrying the expression, which is then run for each element. Python ...

Working with complex programs that run for thousands of lines produces two fundamental problems arise – managing the code to know which functionality is implemented where and debugging the program in case of an error. Fortunately, both problems can be solved by breaking the code into multiple modules and then creating a single script file from the different modules. Python provides this exact functionality where different python modules can be bundled into a single executable script. This functionality allows for easy management and debugging of complex programs. Using zip One way of bundling multiple modules in python is by creating ... Read More
