30 Popular Python Libraries You Must Know

In this Python article, we learn about 30 popular Python libraries you must know. Python Libraries are a set of useful functions that eliminate the need for writing codes from scratch.

There are over 137,000 python libraries present today, and they play a vital role in developing machine learning, data science, data visualization, image and data manipulation applications, and more. Let us briefly introduce Python Programming Language and then directly dive into the most popular Python libraries.

Guido Van Rossum’s brainchild – Python, which dates back to the ’80s, has become an avid game changer. It is one of the most popular coding languages today and is widely used for a gamut of applications. So, how to make an app using Python? Let’s find out.

What is a Library?

A library is a collection of pre-combined codes that can be used iteratively to reduce the time required to code. They are particularly useful for accessing the pre-written frequently used codes instead of writing them from scratch every single time. Similar to physical libraries, these are a collection of reusable resources, which means every library has a root source. This is the foundation behind the numerous open-source libraries available in Python. 

What is a Python Library?

Python library is a collection of modules that contain functions and classes that can be used by other programs to perform various tasks.

30 Popular Python Libraries You Must Know

Migrating From Jira Server: Guide, Pros, And Cons

February 15, 2022 marked a significant milestone in Atlassian’s Server EOL (End Of Life) roadmap. This was not the final step. We still have two major milestones ahead of us: end of new app sales in Feb 2023, and end of support in Feb 2024. In simpler words, businesses still have enough time to migrate their Jira Server to one of the two available products – Atlassian Cloud or Atlassian DC. But the clock is ticking. 

Jira Cloud VS Data Center

If we were to go by Atlassian numbers, 95% of their new customers choose cloud. 

“About 80% of Fortune 500 companies have an Atlassian Cloud license. More than 90% of new customers choose cloud first.” – Daniel Scott, Product Marketing Director, Tempo

So that’s settled, right? We are migrating from Server to Cloud? And what about the solution fewer people talk about yet many users rely on – Jira DC? 

Both are viable options and your choice will depend greatly on the needs of your business, your available resources, and operational processes. 

Let’s start by taking a look at the functionality offered by Atlassian Cloud and Atlassian DC.

Pros and cons of Jira Cloud

When talking about pros and cons, there’s always a chance that a competitive advantage for some is a dealbreaker for others. That’s why I decided to talk about pros and cons in matching pairs. 

Pro: Scalability is one of the primary reasons businesses are choosing Jira Cloud. DC is technically also scalable, but you’ll need to scale on your own whereas the cloud version allows for the infrastructure to scale with your business. 

Con: Despite the cloud’s ability to grow with your business, there is still a user limit of 35k users. In addition to that, the costs will grow alongside your needs. New users, licenses, storage, and computing power – all come at an additional cost. So, when your organization reaches a certain size, migrating to Jira DC becomes more cost-efficient.

Pro: Jira takes care of maintenance and support for you.

Con: Your business can suffer from unpredicted downtime. And there are certain security risks.  

Pro: Extra bells and whistles: 

  • Sandbox: Sandbox is a safe environment system admins can use to test applications and integrations before rolling them out to the production environment. 
  • Release tracks: Admins can be more flexible with their product releases as they can access batch and control cloud releases. This means they’ll have much more time to test existing configurations and workflows against a new update. 
  • Insight Discovery: More data means more ways you can impact your business or product in a positive, meaningful way. 
  • Team Calendars: This is a handy feature for synchronization and synergy across teams. 

Con: Most of these features are locked behind a paywall and are only available to either Premium and Enterprise or only Enterprise licenses (either fully or through addition of functionality. For example, Release tracks are only available to Enterprise customers.) In addition, the costs will grow as you scale the offering to fit your growing needs. 

Pros and cons of Jira Data Center

I’ll be taking the same approach to talking about the pros and cons as I did when writing about Atlassian Cloud. Pros and cons are paired. 

Pro: Hosting your own system means you can scale horizontally and vertically through additional hardware. Extension of your systems is seamless, and there is no downtime (if you do everything correctly). Lastly, you don’t have to worry about the user limit – there is none. 

Con: While having more control over your systems is great, it implies a dedicated staff of engineers, additional expenses on software licensing, hardware, and physical space. Moreover, seamless extension and 0% downtime are entirely on you.

Pro: Atlassian has updated the DC offering with native bundled applications such as Advanced Roadmaps, team calendars and analytics for confluence, insight asset management, and insight discovery in Jira Service Management DC.

Con: Atlassian has updated their pricing to reflect these changes. And you are still getting fewer “bells and whistles” than Jira Cloud users (as we can see from the feature comparison). 

Pro: You are technically safer as the system is supported on your hardware by your specialists. Any and all Jira server issues, poor updates, and downtime are simply not your concern.
 

Con: Atlassian offers excellent security options: data encryption in transit and rest, to mobile app management, to audit offerings and API token controls. In their absence, your team company has to dedicate additional resources to security. 

Pro: Additional benefits from Atlassian, such as the Priority Support bundle (all DC subscriptions have this option), and the Data center loyalty discount (more on that in the pricing section.)

The Pricing

Talking about pricing of SaaS products is always a challenge as there are always multiple tiers and various pay-as-you go features. Barebones Jira Cloud, for instance, is completely free of charge, yet there are a series of serious limitations. 

Standard Jira Cloud will cost you an average of $7.50 per user per month while premium cranks that price up to $14.50. The Enterprise plan is billed annually and the cost is determined on a case-by-case basis. You can see the full comparison of Jira Cloud plans here. And you can use this online calculator to learn the cost of ownership in your particular case.

  • There are certain discounts for apps depending on your partnership level.
  • Depending on your situation, you may qualify for several Jira Data Center discount programs:

What should be your User Migration strategy?

Originally, there were several migration methods: Jira Cloud Migration Assistant, Jira Cloud Site Import, and there was an option to migrate via CSV export (though Jira actively discourages you from using this method). However, Jira’s team has focused their efforts on improving the Migration Assistant and have chosen to discontinue Cloud Site Import support.

Thanks to the broadened functionality of the assistant, it is now the only go-to method for migration with just one exception. If you are migrating over 1000 users and you absolutely need to migrate advanced roadmaps – you’ll need to rely on Site Import. At least for now, as Jira is actively working on implementing this feature in their assistant.

Here’s a quick comparison of the options and their limitations.

 FeaturesLimitations
Cloud Migration AssistantApp migration

Existing data on a Cloud Site is not overwritten

You choose the projects, users, and groups you want to migrate

Jira Service Management customer account migration

Better UI to guide you through the migration

Potential migration errors are displayed in advance

Migration can be done in phases reducing the downtime

Pre- and post-migration reports
You must be on a supported self-managed version of Jira
Site ExportCan migrate Advanced RoadmapsApp data is not migrated

Migration overrides existing data on the Cloud site

Separate user importUsers from external directories are not migrated

No choice of data you want or don’t want migrated

There’s a need to split attachments into up to 5GB chunks

Higher risks of downtime due to the “all or nothing” approach

You must be on a supported self-managed version of Jira

Pro tip: If you have a large base of users (above 2000), migrate them before you migrate projects and spaces. This way, you will not disrupt the workflow as users are still working on Server and the latter migration of data will take less time. 

How to migrate to Jira Cloud

Now that we have settled on one particular offering based on available pricing models as well as the pros and the cons that matter the most to your organization, let’s talk about the “how”. 

How does one migrate from Jira Server to Jira Cloud?

Pre-migration checklist

Jira’s Cloud Migration Assistant is a handy tool. It will automatically review your data for common errors. But it is incapable of doing all of the work for you. That’s why we – and Atlassian for that matter – recommend creating a pre-migration checklist.   

Smart Checklist will help you craft an actionable, context-rich checklist directly inside a Jira ticket. This way, none of the tasks will be missed, lost, or abandoned. 

Below is an example of how your migration checklist will look like in Jira. 

Feel free to copy the code and paste it into your Smart Checklist editor and you’ll have the checklist at the ready.

Use backups

On the one hand, having all of your Jira products on a server may seem like a backup in and of itself. On the other hand, there are data migration best practices we should follow even if it’s just a precaution. No one has ever felt sorry for their data being too safe. 

In addition, there are certain types of migration errors that can be resolved much faster with having a backup at hand. 

  1. Jira Server Database backup: this step creates a DB backup in an XML format.
    1. Log in with Jira System Admin permissions
    2. Go to system -> Import and Export -> Backup Manager -> Backup for server.
    3. Click the create Backup for server button. 
    4. Type in the name for your backup. 
    5. Jira will create a zipped XML file and notify you once the backup is ready. 

  1. Jira Cloud Backup: This backup also saves your data in an XML format. The process is quite similar to creating a Jira Server backup with the only difference taking place on the Backups page.
    1. Select the option to save your attachments, logos, and avatars.
    2. Click on the Create backup button. 

  1. As you can see, the Cloud backup includes the option to save attachments, avatars, and logos. This step should be done manually when backing up Server data.
    1. Create a Zip archive for this data
    2. Make sure it follows the structure suggested by Atlassian

Migrating your Jira instance to the cloud via the Jira Migration Assistant

Jira Cloud Migration Assistant is a free add-on Atlassian recommends using when migrating to the cloud. It accesses and evaluates your apps and helps migrate multiple projects. 

Overall, the migration assistant offers a more stable and reliable migration experience. It automatically checks for certain errors. It makes sure all users have unique and valid emails, and makes sure that none of the project names and keys conflict with one another. 

This is a step-by-step guide for importing your Jira Server data backup file into Jira Cloud.

  1. Log into Jira Cloud with admin permissions
  2. Go to System -> Import and Export -> External System Import
  3. Click on the Jira Server import option

  1. Select the backup Zip you have created 
  2. Jira will check the file for errors and present you with two options: enable or disable outgoing mail. Don’t worry, you will be able to change this section after the migration process is complete. 
  3. Then you will be presented with an option to merge Jira Server and Jira Cloud users
    1. Choosing overwrite will replace the users with users from the imported files
    2. The merge option will merge groups with the same name
    3. Lastly, you can select the third option if you are migrating users via Jira’s assistant
  4. Run the import

How do you migrate Jira Server into Jira DC?

Before we can proceed with the migration process, please make sure you meet the following prerequisites:

  1. Make sure you are installing Jira on one of the supported platforms. Atlassian has a list of supported platforms for Jira 9.1.
  2. Make sure the applications you are using are compatible with Jira DC. You will be required to switch to datacenter-compatible versions of your applications (they must be available). 
  3. Make sure you meet the necessary software and hardware requirements:
    1. You have a DC license
    2. You are using a supported database, OS, and Java version
    3. You are using OAuth authentication if your application links to other Atlassian products

Once you are certain you are ready to migrate your Jira Server to Jira Data Center, you can proceed with an installation that’s much simpler than one would expect.

  1. Upgrade your apps to be compatible with Jira DC
  2. Go to Administration -> Applications -> Versions and licenses
  3. Enter your Jira DC License Key
  4. Restart Jira

That’s it. You are all set. Well, unless your organization has specific needs such as continuous uptime, performance under heavy loads, and scalability, in which case you will need to set up a server cluster. You can find out more about setting up server clusters in this guide.
