C was tied to unix and C ++ was on the coattails of C. Java was actively sold to every major corporation in the early aughts. I will agree, that python came up without a platform to support it.
What about numpy (+ its ecosystem, scipy/pandas/etc)? I get the impression that's contributed a lot to Python's growth over the years.
as i typed that i thought: python is the excel of programming languages.
it also has very solid web frameworks (Django, Flask, etc.).
