Python Developers Survey 2018 Results: The community knowledge

In the fall of 2018, the Python Software Foundation together with JetBrains conducted the official annual Python Developers Survey for the second time. Much like the previous survey, we set out to identify the latest trends and gather insight into how the world of Python development looks at the end of 2018. Over twenty thousand developers from more than 150 different countries participated last year to help us map out an accurate, up-to-date landscape of the Python community. That is more than twice as many Python users participating in 2018 as in 2017.


We are super-excited to share the results of the survey with you!

We hope the survey findings will help all of us better understand the current state of the Python developer community, see the big picture, and answer some potential questions. Find out about the most popular types of Python development, trending frameworks, libraries and tools, additional languages used together with Python, adoption rates of different Python versions, and gain many other insights into the world of Python.

We couldn’t include all the potential findings into the report without bloating it. If you have specific questions that are unanswered, send them to us and we’ll dig into the data for an answer. Or if you want to delve into the data yourself, we’re also sharing the raw survey data, which anyone can use to arrive at their own conclusions and additional findings.

We’ll be glad to learn about your findings! Please share them on twitter or other social media mentioning @jetbrains‏ and @ThePSF with the #pythondevsurvey hashtag. We’re also extremely open to any suggestions and feedback related to this survey so we can run an even better one next time. Feel free to open issues here with any comments or questions.

Huge thanks to all the participants of the survey and to the amazing team at PSF and JetBrains that worked hard to make this happen!

The New Toolbox App 1.13 with Android Studio inside!

TL;DR: the 1.13 update includes support for Android Studio, a new toggle to update all the tools you have installed automatically, a downgrade option, refreshed Settings UI, and bug fixes.

Download now

Android Studio support

We are excited to announce the new version of Toolbox App, which comes with an eagerly awaited feature as voted for by you – support for Android Studio! It is now possible to install Android Studio as you would any other IDE from Toolbox App, making it possible to manage the installations with ease and keep up-to-date with all the changes coming from Google. While JetBrains Toolbox App is exclusive to JetBrains Products, we have made an exception with the inclusion of Android Studio, due to not only the very high demand as mentioned previously, but also because of the great collaboration we have with Google, and the sharing of a common platform. We’d like to thank everybody on the Android Studio team at Google for making this possible.
Toolbox App 1.13

Here are the highlights of the possibilities that come with Android Studio in Toolbox App 1.13:

Go to Android Studio Settings and choose to update to Release or Release and Canary.
Android Studio Settings in Toolbox App 1.13
Turn on the auto-update option in Android Studio Settings and make sure you are always working with the newest version.

Roll back
To quickly roll back to the previous version click the Settings icon and push the changes.

What’s new
When a new version comes out you will see the What’s New link near the installed IDE. Click it to read all about the new features and bug fixes being introduced in the version right inside Toolbox App.
What's new in Toolbox App 1.13

  • Open projects in Android Studio right from the Toolbox App Projects tab.
  • Pin your favorite project to the top of the list in the project Settings.

Projects in Toolbox App 1.13

1.13 also brings the following features

Refreshed Settings UI. We have changed the UI around a little by moving the Quit Toolbox App button and Back button up to the header on all Settings pages.

“Update all tools automatically” toggle in Toolbox App Settings. From now on you can automatically update all the tools which are installed with a new toggle in the Toolbox App Settings.
“Update all tools automatically” toggle in Toolbox App
Downgrade action. This new feature allows you to re-download the previous version from the tools server. Unlike the roll back feature it doesn’t require a previous build to be stored on your disk.
Downgrade action
Package size reduction. We have reduced the size of Toolbox App package by up to 25% depending on the OS, especially for those of you who value free space on your disc.

And of course we fixed some bugs:

  • The behavior of generated shell scripts on Windows and macOS is improved: they are now started in background and support opening the current directory in the IDE.
  • Adding the projects to favorites is now working from the first click.
  • In some cases, duplicate notifications were shown when there was an update available. We’ve fixed that.

For more information please check out the release notes.

We want to thank all our users for their feedback and the positive vibes they shared with us. We read every tweet you write and we are delighted when you share your best wishes mentioning @JBToolbox. (No, really, we rejoice like little children!)
And, we want to thank those evaluators who have helped make the Toolbox App releases in 2018 soft and stable. Special thanks go to the following contributors:

Chris (vqrslogin)
Eduard Wirch
Raphael Reitzig
Kirill Rakhman
Victor Turansky
Victor Alenkov

In appreciation of your valuable efforts, we are giving each of you a free 1-year subscription to All Product Pack. You will receive a personal email with details on how to claim your license.

Developer Ecosystem Survey 2019 is Live. Participate!

At JetBrains, we strive to build tools that make developers more productive. To make our tools more relevant and useful for you, we want to know what is happening in the field of software engineering. This is why we are announcing the start of our third Developer Ecosystem Survey 2019.

If you’re part of the IT industry, please take the survey to share your experiences. The survey should take about 10-15 minutes and is available in 8 languages.

Developer Ecosystem Survey 2019

As a token of our appreciation, we will enter you into our prize draw where you’ll have the chance to win an incredible prize of your choice: an iPad Pro, a $250 Amazon certificate, Arduino Robot Kit, or a JetBrains Surprise Gift Pack.

After the survey is over, we will as always share the results and interesting findings, including the anonymized raw data so you can dig deeper and form your own insights.

This is the third dev ecosystem survey that we are conducting at JetBrains. Last year we had more than 15,000 participants from more than 100 countries.

This year’s survey covers even more programming languages and technologies. And yet, any particular respondent will see fewer questions, because we’re now tried to make it as short as possible to everyone.

Join us in understanding the industry better!

Invite your friends to take this survey, too! With your help, the study will better reflect our community and the whole world of developers.

Data Science Survey 2018 Results By Numbers

Data Analysis, Machine Learning, and AI are rapidly growing in popularity and drawing more and more attention in tech news. How does the data science world look today and how is this industry sector evolving? What types of activities are data scientists primarily involved in? What programming languages and tools are in use? To answer these and many other important questions, last spring JetBrains conducted a Data Science Survey collecting responses from over 1,600 data scientists living in the US, Europe, Japan, and China.

We are super-excited to share with you some of our incredible findings, along with the raw survey data which you can use to draw your own conclusions!

Did you know that Python is now the most popular language among data analysts and engineers? How about that most people assume that Python will remain the primary programming language for data science for the next 5 years? Learn more about these and other insights in the survey infographic:


View the results of Data Science Survey 2018

Key Takeaways

  • Data processing, data visualization, and basic statistics are the top three activities that data scientists are involved in.
  • Python is the main programming language for data analysis with most users not willing to migrate to other languages.
  • Most of the respondents believe that Python will remain top for the next 5 years.
    7% of respondents identified as not professional data scientists want to adopt Kotlin in the nearest future.
  • Apache Spark, Apache Hadoop, and Apache Hive are the top three big data tools.
  • Jupyter Notebook is the top code editing tool for people involved in data science, followed by PyCharm and RStudio.
  • Nearly 80% of those using deep learning libraries use TensorFlow.
  • 78% of respondents use their local machines to perform computations.
  • AWS is the most popular cloud service provider among data scientists.
  • 81% of data scientists analyze data for non-IT industries.
  • Get more insights from the full report.


We distributed the survey via targeted ads on Facebook, LinkedIn, and Twitter. We filtered out those replying “I’m not involved in data analysis” with the first questions. In the US, Japan, and China, we collected 400 complete and valid sets of responses from each country, and we used quotas to get another 400 responses from European countries.

Important Note: Some inevitable bias may be present since the survey was organized and promoted by JetBrains and some JetBrains users might have been more willing to participate.

Want to dig into the raw survey data to draw your own conclusions?

We couldn’t include all the potential findings in the report without it becoming bloated. If you have any specific questions that are unanswered, send them to us and we’ll dig into the data for you for an answer. Or if you want to delve into the data yourself, we’re also sharing the raw survey data, which anyone can use to arrive at their own conclusions and additional findings. PDF version of the infographic is also available if you’d like to print it out or read it as a file.

We hope the survey findings will help all of us better understand the current state of the Data Science community, see the big picture, and get answers to some of our burning questions. We’d be very interested to learn about your findings! Please share them on Twitter or other social media, mentioning @jetbrains‏ with the #datasciencesurvey hashtag. We’re also extremely open to any suggestions and feedback related to this survey so we can run an even better one next time.

Finally, we would like to just say a huge thanks to the participants of the survey!

Developer Ecosystem Survey 2018: Raw Data Available

Early this year, we ran our second yearly Developer Ecosystem Survey to reveal the most significant facts about developers and technologies.

Since this June, we’ve been sharing these Infographics showcasing the most interesting results and insights from an even broader range of developer topics than last year.

As the study consisted of over 150 questions, it was impossible to cover them all in the Infographics. So now, same as last year, we are publishing the anonymized raw data from the survey. If you’re interested in discovering development trends, be our guest – go right ahead, dig deeper into the data, draw your own conclusions and glean additional insights like we did!

DevEcosystem18 Raw Data Is In

What kind of interesting facts did we dig up? Well, we found out that JetBrains customers code for 5 hours (21%) a week more on average than those who don’t use JetBrains tools! At the same time, they get 15 more minutes of sleep (that’s 5%) than the average coder. Fascinating stuff! Maybe it’s because JetBrains users love programming and sleeping, but programming more!

Before analyzing these data, please keep in mind the following facts about the sample:

  1. The data-set includes all of the 13,000+ responses collected from January to April of 2018 from both JetBrains “internal” and “external” channels. By “external” channels we mean channels such as Facebook Ads, Twitter Ads, and Google Adwords. By “internal” channels we mean JetBrains’ own communication channels such as our blog post, JetBrains Twitter accounts, JetBrains Facebook, and the JetBrains’ Internal Survey Panel. When comparing your own results with our Infographics results, please bear in mind that to minimize possible bias, the data of the Infographics include only responses coming from advertising (external channels).
  2. The data are anonymized, with no personal information or geolocation details. Moreover, to prevent the identification of any individual respondents by their verbatim comments, we have purged all open-ended fields. We have also merged any answer options that collected fewer than 10 responses into the “Other” answer option.
  3. The data are not weighted. We used our own population weights for post-stratification of Infographic data, to correct for the fact that countries with similar sample sizes may have different actual numbers of developers. We’re not sharing these population weights so you’ll need to apply your own weights when analyzing the data.
  4. To better understand the logic of the survey, along with the data-set we’re sharing the survey questions, with all the survey logic, in English.

Thanks everyone one more time for participating in our study. Your voice matters!

Don’t miss the chance to participate in Developer Ecosystem Survey 2019 – join the JetBrains Survey Panel today.

Happy analyzing!
