HTML/CSS came a close second with 61% saying they had used it in the past 12 months, followed by SQL at 56% and Java at 50%. Although Python was only fifth on the list, used by just under half of developers (49%), it shows significant potential growth: 9% of respondents said they intended to adopt it or migrate to it.

Python was also ranked as the most studied language: 27% of respondents have started or continued to learn Python in the past 12 months. Data analysis, web development, and machine learning were listed as its top three uses by developers.
But according to JetBrains, Go is considered the most promising programming language. Currently used by just 18% of developers (up from 8% in last year's survey), almost as many again – 13% – identified it as a language they would like to adopt or migrate to.
JetBrains noted that there is a group of 'secondary' languages – used mainly as an additional language – which include HTML, SQL, and Shell scripting: "A lot of software developers have some practice with these secondary languages, but very few work with them as their major language." JetBrains surveyed 6,993 developers: 69% were employed full time, 15% were students and 12% were self employed or freelance.
