JavaScript is the most popular language used together with Python. However, for developers who use Python as a secondary language, C/C++ are about as popular as JavaScript. HTML/CSS, Bash/Shell, and SQL are also widespread, each being used by more than a third of Python developers.

Web development refers to people who selected “Web development” in response to the question “What do you use Python for the most?”. Data science refers to people who selected “Data analysis” or “Machine Learning” in the same question.

Unsurprisingly, the most popular languages used along with Python by web developers are JavaScript (69%) and HTML/CSS (60%), while developers involved in data-related tasks more often use SQL (42%). Also, the share of developers who don’t use any additional languages is three times higher among those who are involved in data-related tasks, compared to web developers.

Making Python Better

Did you know?

In 2021, The Python Software Foundation appointed a new Developer-in-Residence to work full-time on the Python programming language and support its developer community.

Core developer Łukasz Langa was hired to the CPython DIR role in July. Langa is working to help clear the backlog, investigate project priorities, and look into other areas of interest.

23% of Python developers already know about the Developer-in-Residence role, and 91% of them find this initiative good.

Moreover, 30% of developers who are aware of the Developer-in-Residence role already see the impact of this innovation.

Reporting the issues

Only 19% of Python users have ever reported its bugs. Interestingly, using bugs.python.org is not the most popular way to report them – about twice as many programmers prefer to ask elsewhere or submit a pull request to GitHub.

Of those who reported bugs, 73% got their issue solved, and only 7% of respondents say they have never heard back from anybody.

Methodology and Raw Data

Want to dig further into the data? Download the anonymized survey responses and see what you can learn! Share your findings and insights by mentioning @jetbrains and @ThePSF on Twitter with the hashtag #pythondevsurvey.

Before dissecting these data, please note the following important information:

The data set includes responses only from official Python Software Foundation channels. After filtering out duplicate and unreliable responses, the data set includes more than 23,000 responses collected between October 11 and December 6, 2021, through the promotion of the survey on python.org, the PSF blog, the PSF’s Twitter and LinkedIn accounts, official Python mailing lists, and Python-related subreddits. In order to prevent the survey from being slanted in favor of any specific tool or technology, no product, service, or vendor-related channels were used to collect responses.

The data is anonymized, with no personal information or geolocation details. To prevent the identification of any individual respondents by their verbatim comments, all open-ended fields have been deleted.

To help you better understand the logic of the survey, we are sharing the data set, the survey questions, and the survey logic. We used different ordering methods for answer options (alphabetic, randomized, and direct). The order of the answers is specified for each question.

Criteria for filtering out responses

  • Age 17 or younger.
  • Did not reach the question “How many years of professional coding experience do you have?” on the third page of the survey.
  • Age under 21 and more than 11 years of professional coding experience.
  • Too many single answers for multiple choice questions (excluding “None” answers).
  • Responses from the same email addresses (only one response left within).
  • Similar responses from the same IP address.

At least two of the following:

    • More than 16 programming languages used.
    • More than 9 job roles.
    • More than 11 Python usage purposes (​​”What do you use Python for?”).
    • Selected country/region is among the top of the list alphabetically, not among popular countries/regions, and differs from the IP-detected country/region.
    • CEO and Technical Support job roles together.
    • CEO and age under 21 together.
    • Too many answers selected overall (those, who use almost all frameworks for data science, for web development, packaging, etc.).
    • Answered too quicky (less than 6 second per question).
