tl;dr: What is a less extreme (but still noticeable) alternative to the word "fluent", when saying e.g. "I am fluent in C++/Python/whatever?"
I think I can call myself "fluent" in C#, because I know the language and runtime very well, and I'm very familiar with the .NET framework's APIs and classes, etc.
I would like to claim the same thing for Python and C++.
But while I can program in Python (I did so for an entire summer, making a website with Django), for example, I would not call myself fluent because my code isn't always "Pythonic" (e.g. using
filter vs. list comprehensions), and I'm not too intimate with some aspects of the language and standard library yet (e.g. the introspection API, etc.).
Is there a word or phrase I can use on e.g. a resume to describe what I know?
I can think of "very familiar with", but is there a better word/phrase I can use?
