 Cc tscrim added
 Description modified (diff)
 Status changed from new to needs_review
The most significant changes are in graph_input.py
as I changed some tests.

For this change:
 if not loops and any(u in neighb for u,neighb in six.iteritems(M)):  if loops is False:  u = next(u for u,neighb in six.iteritems(M) if u in neighb)  raise ValueError("The graph was built with loops=False but input M has a loop at {}.".format(u))  loops = True  if loops is None:  loops = False + if any(not isinstance(M[u], dict) for u in M): + raise ValueError("input dict must be a consistent format") + + if not loops: + for u, neighb in six.iteritems(M): + if u in neighb: + if loops is False: + raise ValueError("the graph was built with loops=False but input M has a loop at {}".format(u)) + loops = True + break + if loops is None: + loops = False
the any
call is actually faster. Granted, your change will result in a faster error, but I think an error message being here is unexpected. Hence it is allowed to be slow. If someone really wants the extra speed and is using that test to separate cases, they should run their own test instead of catching the error (which is faster). So I am inclined to revert this.
Also, strictly speaking, the items for INPUT:
are not sentences and do not end in a period (although some of them are sufficiently long with multiple parts that require it). While I was letting this slide when it was previously there, the ones you are adding should not have it.
All of the other changes LGTM.

comment:5 Changed 18 months ago by
The following lines are apparently incompatible with Python 3 (see patchbot).
+ if any(u in neighb for u,neighb in six.iteritems(M)):
+ u = next(u for u,neighb in six.iteritems(M) if u in neighb)
+ if any(u in neighb for u, neighb in six.iteritems(D)):
+ u = next(u for u, neighb in six.iteritems(M) if u in neighb)
Is there a special trick or should I turn these lines to for loops ?
comment:6 Changed 18 months ago by
No, no. It's just the patchbot prefering "iteritems" to "six.iteritems". Just change the imports accordingly.
And once again, it is never mandatory to have all green lights from the patchbot, as the patchbot is not smart..

comment:8 Changed 18 months ago by
Good to know. As I'm not Python 3 expert, I thought it could be something else.

Doctest failures:
File "src/sage/graphs/digraph.py", line 399, in sage.graphs.digraph.DiGraph Failed example: D = DiGraph('IRAaDCIIOEOKcPWAo') Expected: Traceback (most recent call last): ... RuntimeError: The string (IRAaDCIIOEOKcPWAo) seems corrupt: for n = 10, the string is too short. Got: Traceback (most recent call last): ... RuntimeError: the string (IRAaDCIIOEOKcPWAo) seems corrupt: for n = 10, the string is too short
and similar in graph.py
. Once fixed and the patchbot comes back green, then it will be a positive review.
