I've done concurrent programming in both Python and Go, and to be fair to Python, its standard library queue class (http://docs.python.org/library/queue.html http://docs.python.org/library/queue.html) is very close to Go's channels so it does CSP style concurrency quite nicely. However, Go's goroutines are IMHO superior to Python threads since they're much more lightweight and can run in parallel on multi-core CPUs and you can have a lot more of them. Go gets it right by putting goroutines and channels into the core language to encourage CSP style concurrency, but putting other more traditional, but harder-to-use, concurrency primitives like mutexes into the standard library.
