After #21687 there are 341 lines in 172 files with

What can happen in, say has_vertex() in generic graphs, when it has the

     try:

     except Exception:
         return False
     return self._backend.has_vertex(vertex)

I.e. what if hash() runs out of memory or something like that?

What you expect. A MemoryError will be raised, which is caught by the 
"except Exception".

So I agree that code like the above is bad (but not nearly as bad as a 
bare "except:")
