A Guide To Pipenv

The “Python Development Workflow for Humans”, or “Pipenv”, was created by Kenneth Reitz in 2017. It is now recognized as the official Python-recommended resource for managing package dependencies. But there is still widespread confusion about what problems it is supposed to solve and its usefulness in solving them. The standard workflow uses pip and a “requirements .txt file”, but it is necessary to find out if Pipenv is more useful. This, therefore, is a brief guide to Pipenv.

Dependencies

These are the results created whenever one class depends on another class, for example, if class A depends on a class B to function, then class A is called a ‘dependant’, while class B is known as a ‘dependency’. In order to use or re-use class A, class B must also be used or re-used. Whenever Object Oriented Design (OOD) of API’s and Applications are done, dependencies and their removal become important. Any discussion on OOP (Object Oriented Programming) is incomplete without mentioning dependencies loose couplings.

Two classes that use each-other are said to be ‘coupled’. The couplings between classes can be loose or tight or a bit of both. In reality, the degree of tightness is continuous, and is often characterized as ‘strong’ or ‘weak’. But dependencies represent weaknesses in OOP. Dependencies decreases re-use. Re-use always impact Development Speed positively, as well as, Code Quality and Code Readability. There are three general types of dependencies. These are Class, Interface and Method/Field dependencies. Dependencies also have important characteristics. They can be Run-time, Compile-time, Hidden or Visible, Local and Contextual, Direct or Indirect. But whatever they are, they need to be eliminated, or at least managed.

Pipenv

Pipenv is a Tool that aims to bring the best of all packaging worlds to Python. In other words, npm, bundler, cargo, composer, yarn etc. are all included in a single Tool. Its specialty is to automatically create and manage a virtualenv for the developer’s projects, as well as adding or removing packages from the Pipfile, while installing or uninstalling packages. At the same time, Pipenv generates the Pipfile, which is important in order to create deterministic builds.

The main target is to create a working environment with ease for developers and users alike. Pipenv not only addresses some common issues, but also freezes the development process to a simplified single command line tool. One of the major benefits of using Pipenv is handling of a typical situation of third-party packages. For example, if we were using ‘Flask’, a third-party pack, we would need to specify that requirement so that other developers and automated systems can also run the application. A new version of Flask may have got released, but maybe it is backward compatible with the version used during development. Now if that application is deployed to production, and a Pip install ‘-r requirements.txt’ is done, Pip having got Flask, the latest compatible-not-backward version, the application will break in production.

Pipenv allows for deterministic builds for any Python project, ranging from all types of mobile applications like free fuck sites and dating platforms to ecommerce and conent websites, without the additional responsibility of updating versions of sub-dependencies. Pipenv allows the development of projects in Python with different dependencies. If, for example, different versions of Django are used on two projects A and B, every-time it is needed to switch between Project A and Project B, you have to uninstall all the packages in Project A based, based on one version of Django, and install all the packages based on the other version of Django compatible to the use of Project B. This is not only time consuming, but actually painful. A standard solution for regular switching between projects is to use a virtual environment that has its own third-party package storage in Python. Pipenv has a virtual environment already built in and so eliminates the effort for creating virtual environment each time this is required. This feature of Pipenv is called ‘Venv’ (Virtual Environment).

Pipenv Features

Pipenv is a growing next gen Python Dependency Management Tool. Some of the salient features of Pipenv are:

Pipenv abridges the route of organizing dependencies and creating a virtual environment.
By specific versions to locking dependencies, Pipenv guarantees that builds of the package are reproducible.
Pipenv works by specifying development dependencies and separate core in different parts of the same file to replace separate dependencies files.
Pipenv can be used to both manage and publish packages.
Pipenv is supported by Python directly and regularly release updates and versions. The last version was released on November 26th 2018.
When first released, upgrading any single package of Pipenv, would upgrade all dependencies. This behavior, however, is now being corrected.
The Pipenv ‘install’ command is dual purpose. Only the package specified will be installed, leaving the others untouched. If no package is specified, all (non-dev) dependencies are also installed.
Pipenv is supported officially by the Python Packaging Authority (PPA) and also by the Hiroku Python Builtpack (HPB), and this is important to developers with Dokku or Hiroku- based deployment strategies.
Pipenv supports being able to export a ‘requirement.txt’ file.
However, Pipenv seems to have some flaws from birth which, if not corrected immediately, can lead to confusion. Pipenv commands and options are often confusing and unclear, and many options are not available. Many User’s patience are sorely tested by regression issues of Pipenv. Tested against cross platform and multi-environment is not only complicated and difficult, it is very time consuming.

The Pipfile

Pipenv has to solve the package installation problem to the Pip Library for plus two libraries for creating and to manage virtual environments, also all the commands in association with the libraries. Pipenv abandons the ‘requirements.txt’ norm for a new document known as Pipfile to achieve the dependency management. When installing Pipenv Library, a Pipfile for the project is involuntarily updated with installation details, including information version and possibly the file path and other information like Git repository location. An additional Pipfile.lock keeps track of the app’s interdependencies and also verifies that the right dependency versions are used in production.…

Intro to Developing Websites With WordPress

The task of designing a website may seem overwhelming and even impossible for people without the proper background and skills. So many people want to create their own websites, but when the time comes, they tend to shy away. This is because there’s a general belief that web designing is hard and requires special skills. Well, we’re here to clear that up! There’s a web design software out there called WordPress that anyone can use. It’s a simple yet effective tool if you want to create your own website.

If you’re someone who’s looking to make a website, then consider using WordPress. It’s going to make things much easier and simpler for you. Even if you do not have a background in computer sciences, you can easily navigate the program and end up creating a stunning website. The best part is that the program is free. You don’t need to spend tons of money hiring someone to create a website for you. All the resources to create a website are all available on WordPress. Here are some tips you should know on how to use WordPress to create a website.

What exactly is WordPress?

WordPress is essentially a web building software. It’s something that everyone can use, even those without proper skills in coding or computer scripts. The software contains plugin architecture and even has a template feature. This makes it easier for users to customize and personalize the website to their liking. They can choose from an array of different layouts, designs, and even themes to fit their preferences.

In a nutshell, WordPress is essentially a content management system. It’s a great choice for people who want to create websites but are unsure of how to go about it. WordPress is also one of the world’s most popular and go-to options for website design and creation. Anyone can create amazing websites in just a few simple steps.

Choosing the right plan

Although the program itself is free to use, you will need to choose an appropriate plan that will cost you some money. The money you pay is more similar to a monthly fee, and the value depends on the type of website you wish to create. WordPress offers five kinds of plans to its users. This is the first step that you need to complete in your website creation process using WordPress.

The plans that you can choose include the free option, personal, business, premium, and even e-commerce. The only difference between these options is the monthly fees that you need to pay and also the type of customization. If you’re creating a website for personal use or even blogging, the personal option should suffice. However, if you plan on running a business on your website, then the e-commerce or business options seem valid.

Selecting the domain name and host

Once you finish choosing a plan, it’s now time to move on and select a domain name as well as a hosting provider. This step is also simple and does not take much time. The key difference between a domain name and your host provider is that the domain name is your website identity. It is how people will find your website. Host provider, on the other hand, stores all of your site’s data.

WordPress allows users the freedom to decide on a domain name. When it comes to web hosting, WordPress takes care of this aspect for users. You do not need to worry. The reason a web host is important is that it impacts the overall performance of the site. Speed, reliability, and even the security of a website all depend on the host.

If you do not have a domain name or even a host provider, don’t worry! Head on over to Bluehost and select the “get started” option. You will come to the pricing page from which you can select anyone that you deem fit. Once you choose the plan, you will now be directed to create a domain name or even transfer an existing domain name. Once this is done, you will have to pay in the billing section. After payment confirmation, you can now install WordPress CMS.

Install WordPress

Once WordPress gets installed, you need to login into your account. Once you are in, you will get to see the WordPress interface. Now all you need to do is make a primary domain. For this, go over to the domains section and select the domain which you want to make primary. Verify the changes, and you have a primary domain that guests can see.

Customization and adding content

After all the technical stuffs are out of the way, it’s time for a little creativity. You can now select different themes for your site and add your own personal content to your website. WordPress provides users with so many different themes and templates. This makes the customization process easier. Different fonts, colors, sizes, layouts, and even visuals are all available.

Adding posts and pages is also very easy to do using WordPress. Posts and pages are the main type of content for your website. To add a new post, simply head on over to the admin dashboard and select “posts.” Under posts, you need to choose “add new.” You can now start typing new content or adding photos. Click on either “save draft,” or “publish immediately.”

If you wish to add a new page, the process is similar to adding a new post. All you have to do is locate the dashboard and select “pages.” Once you do that, you will find the option “add new.” Click on that, and you’re all ready to add new pages to your website.

More customizations

Adding a theme and content is not the only customizations that are available. If you go over to the admin dashboard and choose “settings,” you can choose to tweak and adjust many aspects of your site. You can change the site title, tagline, time zone, email address. You can even change reading settings, such as having your website content be dynamic or static. Dynamic content displays the newest content at the top. In comparison, static content is useful for business based sites that wish to keep content in one place.

In the admin dashboard, you can also have the option to install a multitude of different plugins for your new website. Plugins are pieces of software that enhances your website’s performance and functionality. You might already have several plugins installed, but if you wish to add a new one, simply click on the “add new” option and click on “activate.”

Conclusion

Who said website creation is hard? With tools such as WordPress, even an impossible and difficult task such as web creation becomes so much easier for many people. If you’re someone who struggles with technology, using WordPress might be your remedy. It makes something as technical as web design and creation as simple as possible.

No matter what type of a website you want, WordPress can definitely help you create it. If you follow our simple step-by-step, you will face no problems in your process of website development. In fact, you might end up enjoying the whole process …
