Questions about numpy and matplotlib have also grown in their share of visits over time. In contrast, traffic to Django questions has stayed fairly steady during that time, and while Flask is growing it remains at a smaller share. This suggests that much of Python's growth may be due to data science, rather than to web development.\u003C\u002Fp>\n\u003Cp>However, this gives us only part of the picture, since it can measure only widely used \u003Cem>Python-specific\u003C\u002Fem> packages. Python is also popular among system administrators and DevOps engineers, who might visit Linux, Bash, and Docker questions alongside Python questions. Similarly, plenty of Python web development is done without Django or Flask, and such developers would likely visit JavaScript, HTML and CSS as \"supporting\" tags. We can't simply measure the growth of tags like \u003Ca href=\"https:\u002F\u002Fstackoverflow.com\u002Fquestions\u002Ftagged\u002Flinux\">linux\u003C\u002Fa>, \u003Ca href=\"https:\u002F\u002Fstackoverflow.com\u002Fquestions\u002Ftagged\u002Fbash\">bash\u003C\u002Fa>, \u003Ca href=\"https:\u002F\u002Fstackoverflow.com\u002Fquestions\u002Ftagged\u002Fjavascript\">javascript\u003C\u002Fa> and assume they're associated with Python. Thus, we'd like to measure the tags \u003Cstrong>visited alongside Python\u003C\u002Fstrong>.\u003C\u002Fp>\n\u003Cp>We'll consider only visits in the summer (June-August) of 2017, which helps reduce the effect of undergraduate students, focuses on recent traffic, and helps reduce the computational challenges of summarizing traffic across long periods of time. We considered only signed-in users who had visited at least 50 Stack Overflow questions during that time. We considered someone a Python user only if \u003Cstrong>a)\u003C\u002Fstrong> their most visited tag is Python, and \u003Cstrong>b)\u003C\u002Fstrong> Python makes up at least 20% of their visits.\u003C\u002Fp>\n\u003Cp>Which tags were often visited by the same people who tended to visit Python?\u003C\u002Fp>\n\u003Cp>\u003Cimg class=\"alignnone size-large wp-image-7815\" src=\"https:\u002F\u002Fstackoverflow.blog\u002Fwp-content\u002Fuploads\u002F2017\u002F09\u002Fcommon_other_tags-1-1024x1024.png\" alt=\"\" width=\"1024\" height=\"1024\">\u003C\u002Fp>\n\u003Cp>\u003Ca href=\"https:\u002F\u002Fstackoverflow.com\u002Fquestions\u002Ftagged\u002Fpandas\">Pandas\u003C\u002Fa> is by a large margin the tag most visited by Python developers, which isn't surprising after we saw its earlier growth. The second most visited tag by Python visitors is JavaScript, which likely represents the set of Python web developers (as does Django a few slots lower). This confirms our suspicion that we should consider what tags are visited alongside Python, and not just the growth of Python-related tags in general.\u003C\u002Fp>\n\u003Cp>Going down the list, we can see other \"clusters\" of technologies. We can examine their relationships by considering what pairs of tags tend to be \u003Cem>correlated\u003C\u002Fem>: that is, whether pairs of Python users are disproportionately likely to visit both tags.

The cluster below describes web development, with tags like JavaScript, HTML, CSS, Django, Flask and JQuery. Two other clusters we can spot are \u003Cstrong>system administration\u002FDevOps\u003C\u002Fstrong> on the left (centered around Linux and Bash), and \u003Cstrong>data engineering\u003C\u002Fstrong> on the right (Spark, Hadoop, and Scala).\u003C\u002Fp>\n\u003Ch3>Growth by topic\u003C\u002Fh3>\n\u003Cp>We've seen how Python-related Stack Overflow traffic can generally be divided into a few topics. This lets us examine which of the topics is responsible for most of Python's growth in Stack Overflow visits.\u003C\u002Fp>\n\u003Cp>Imagine we were looking at the history of a user, and we see that Python is their most visited tag. How might we guess whether they are a web developer, data scientist, system administrator, or something else? Well, we could consider their \u003Cem>second\u003C\u002Fem> most visited tag, then their third, and work our way down the list of their most visited tags until we saw something recognizable from one of the clusters above.\u003C\u002Fp>\n\u003Cp>Thus, we propose the following simple approach for classifying a user into a topic, where we find the tag most visited by each user from the nine listed below, and use that to classify them.\u003C\u002Fp>\n\u003Cul>\n\u003Cli>\u003Cstrong>Data scientist\u003C\u002Fstrong>: Pandas, NumPy, or Matplotlib\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Web developer\u003C\u002Fstrong>: JavaScript, Django, HTML\u003C\u002Fli>\n\u003Cli>\u003Cstrong>Sysadmin\u002FDevOps\u003C\u002Fstrong>: Linux, Bash, or Windows.\u003C\u002Fli>\n\u003Cli>\u003Cstrong>None\u003C\u002Fstrong>: None of the nine tags above made up more than 5% of their traffic.\u003C\u002Fli>\n\u003C\u002Ful>\n\u003Cp>This isn't very sophisticated, but it lets us quickly estimate the influence of each major category on Python's growth. We also tried the more rigorous approach of \u003Ca href=\"http:\u002F\u002Ftidytextmining.com\u002Ftopicmodeling.html\">latent Dirichlet allocation\u003C\u002Fa>, and got qualitatively similar results.\u003C\u002Fp>\n\u003Cp>Which categories of Python developer have become more common over time?

For instance, it's possible that Javascript traffic is steady overall, but that it's shrinking as a percentage of visits from Python developers.

The high traffic to Python questions from universities is therefore due partly to \u003Cem>academic researchers\u003C\u002Fem>, who generally work throughout the entire year.

For example, within finance (one of the larger contributors to Stack Overflow traffic out of these industries), Python went from being the fourth most visited tag in 2016 to the second most visited in 2017.\u003C\u002Fp>\n\u003Ch3>Conclusion\u003C\u002Fh3>\n\u003Cp>As a data scientist who previously worked in Python but now works in R, should this push me towards switching back?\u003C\u002Fp>\n\u003Cp>I don't think so. For one thing, R has been growing rapidly as well; we saw in the last post that it's the second-fastest-growing major programming language, after Python. But secondly, the reasons I prefer using R for data analysis aren't particularly related to its relative popularity. (I'm planning on writing a personal blog post about my own journey from Python to R, what I like about both languages, and why I don't feel compelled to switch back).\u003C\u002Fp>\n\u003Cp>In any case, data science is an exciting and growing field, and there's plenty of room for multiple languages to thrive.
