Not if only one is the right one in all cases.

In python you can also do

  s = set()
  s.add(1)
  s.add(2)

and

  s = set(x for x in [1, 2])

But I wouldn't call that having three ways to do the same.

Disclaimer: I don't know java well, just commenting based on the comments above and my python knowledge.

I think that's fair. As with good UI, I appreciate when I can navigate via intuition. The solution in Python is intuitive, readable, and memorable. When working in Java, I frequently felt compelled to read and review pages of docs in search of a straightforward solution. I'm a sucker for Python's syntactic sugar.

I've never seen a language have a single way to do something. It's part of Python's mission statement, but it doesn't appear to even have been a consideration in practice.
