Complex vs complicated

One of the python principles (zen) says:
Complex is better than complicated

But what is the difference between complex and complicated?

Answer from stackexchange

Complex is used to refer to the level of components in a system. If a problem is complex, it means that it has many components. Complexity does not evoke difficulty.

Complicated refers to a high level of difficulty. If a problem is complicated, there might be or might not be many parts but it will certainly take a lot of hard work to solve.
