Although Java, C, and C++ have seen drops in language popularity, they once again remain atop the Tiobe language popularity index, which uses the number of developers, courses, and vendors for each language to calculate its popularity. Their two main contenders—Python and C#—face obstacles that may keep them in the second tier.
Python actually slipped 1.32 points from its rating a year ago, while C# slipped 0.71 points in the same period.
