Deleting nodes with tie=1 in a large NetworkX graph

由 ≯℡__Kan透↙ 提交于 2021-02-18 19:11:35
问题 I have made large graph with NetworkX with about 20,000 nodes. I would like to delete nodes with only one tie (or zero ties) to try to reduce the clutter. Since it is a very large graph I do not know the nodes by name or ID that have tie=1 or 0. Does anyone know how to delete these nodes without specifying the node ID or name? 回答1: Iterating on a Graph g yields all of g 's nodes, one at a time -- I believe you can't alter g during the iteration itself, but you can selectively make a list of

Google Sheets - How to Combine Filter Function with Filter View

问题 I've been working on a spreadsheet with over 100 rows, and found a hacky way to incorporate a "hide" checkbox that will hide any row where column C matches a specific value (building type), specified beside the box. To do this, I first created a function like this: =FILTER(Data!A1, OR(Data!$C1<>$O$2, $P$2)) and dragged that across every row and column in a seperate sheet. This reads as, "Display current cell if the corresponding column C in that row in Data does not match the building type,

Python: Difference between filter(function, sequence) and map(function, sequence)

问题 I'm reading through the Python documentation to really get in depth with the Python language and came across the filter and map functions. I have used filter before, but never map, although I have seen both in various Python questions here on SO. After reading about them in the Python tutorial, I'm confused on the difference between the two. For example, from 5.1.3. Functional Programming Tools: >>> def f(x): return x % 2 != 0 and x % 3 != 0 ... >>> filter(f, range(2, 25)) [5, 7, 11, 13, 17,

How can I get list of properties in an object in Actionscript?

问题 I have a dataprovider and a filterfunction for my array that's assigned to my dataprovider. How can I get a list of the properties that are in each row of the dataprovider (item.data) as it gets passed to the filterfunction? For instance, if my object contained: Object name email address Then I would want, in my filterfunction to be able to look at name, email and address. Unfortunately, I don't know what these properties will be before hand. Any ideas? 回答1: If it's a dynamic object I believe

How to achieve python's any() with a custom predicate?

问题 >>> l = list(range(10)) >>> l [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> if filter(lambda x: x > 10, l): ... print "foo" ... else: # the list will be empty, so bar will be printed ... print "bar" ... bar I'd like to use any() for this instead, but any() only takes one argument: the iterable. Is there a better way? 回答1: Use a generator expression as that one argument: any(x > 10 for x in l) Here the predicate is in the expression side of the generator expression, but you can use any expression there,

Demo: >>> l = range(10) >>> any(x > 10 for x in l) False >>> l = range(20) >>>
