From what I remember of a presentation they had on how and why the made Go, this is no coincidence. They had a lot of Python glue code at Google, but had issues running it in production due to mismatched library dependencies, typing bugs, etc. So they made Go to be easy to adopt their Python code to (and especially get the people writing that code to switch), while addressing the specific production issues they faced.
