Probably depends on what section of the company you are in. Some probably never use Python, while others may make heavy use of it. I've heard claims ranging from "it depends," to "mostly C++ / Java," to "only Python as a glue language."
Last I heard it was: "Python where we can, C++ where we must"
Link please?
Haha, no. We absolutely write new Python code daily and it's one of our core languages.
Thanks for the update. I was concerned that Guido leaving Google meant more than just Guido leaving Google.
