Why "Python too"?

Google is well known for using Python.

I'm willing to bet this is using ITA's software, which is written entirely in Common Lisp. See my comment above.

I said nothing about this specific product. I was simply simply answering the parents question about the use of Python at Google.

Using python yes. But for building apps with heavy traffic? Most of the SWE jobs on google.com/jobs have a Java/C/C++ requirement, not Python.
