Only yesterday I commented on a related thread I commented[1] thus which lead to a long subthread. It all depends on the first couple of language that one learns and how they are learnt and taught. 10-15 years ago people would find it hard to grok Python's functional concepts. But as it began to be taught as the first language in universities and those graduates join the working population you see how it's super natural for them to grok Python. That said, in a professional environment, one should be able to pickup ~70% of proficiency in 6-8 months if they aren't constrained by crazy timelines. This is based on my own experience.
