Python, not able to graph trees using graphviz with the anytree package

由 ╄→尐↘猪︶ㄣ 提交于 2021-02-05 08:11:19
问题 So I have installed the anytree package (after great effort; I had to add some environment variables on my system). Having done this I can use almost all functionalities of the anytree package - just not the one I want. I wish to use graphviz in conjunction with the anytree package in order to graph trees using the 'DotExporter' command. I have installed graphviz; its path is C:\Users\joel\Anaconda3_2\Lib\site-packages\graphviz, and I have also added the line of code 'from anytree.exporter

问题 Is there a way to read data from a file and construct a tree using anytree? Parent Child A A1 A A2 A2 A21 I can do it with static values as follows. However, I want to automate this by reading the data from a file with anytree. >>> from anytree import Node, RenderTree >>> A = Node("A") >>> A1 = Node("A1", parent=A) >>> A2 = Node("A2", parent=A) >>> A21 = Node("A21", parent=A2) Output is A ├── A1 └── A2 └── A21 回答1: This assumes that the entries are in such an order that a parent node was

问题 I have a nested list like the following: lst = [['a', 'b', 'e'], # this e is the branch of b ['a', 'f', 'e'], # this e is the branch of f, ['a', 'h', 'i i i']] # string with spaces and I wanna to construct a tree like: a ├── b │ └── e ├── f | └── e └── h └── i i i I want to use either of the two packages: treelib and anytree. I've read many posts and tried many different methods and didn't make it work. Update: I came up with the following method, but the problems I have now are the vertical

问题 This question is based on Tarun's Answer for rendering a tree in python using anytree and graphviz: https://stackoverflow.com/a/49442969/2139007 After installing graphviz and adding it to my PATH variables i'am trying to run the following python code: DotExporter(nodes[0]["a"], nodeattrfunc=lambda node: 'label="{}"'.format(node.display_name)).to_picture("tree.png") The above code generates the following error: Error: dot: can't open C:\Users\username\AppData\Local\Temp\tmpa7t554le Traceback

问题 I create a tree with anytree library. I want to be able to modify it, then export - save it to disk, and import it back with the modifications. For instance, the example tree: udo = Node("Udo") marc = Node("Marc", parent=udo) lian = Node("Lian", parent=marc) dan = Node("Dan", parent=udo) jet = Node("Jet", parent=dan) jan = Node("Jan", parent=dan) joe = Node("Joe", parent=dan) Udo ├── Marc │ └── Lian └── Dan ├── Jet ├── Jan └── Joe I can modify it, for instance cutting Dan off and adding a

How to use Selenium to click through multiple elements while avoiding Stale Element Error

由 亡梦爱人 提交于 2019-12-11 06:22:36
问题 I'm working on making somewhat of a site map/tree (using anytree) and in order to do so, I need Selenium to find particular elements on a page (representing categories) and then systematically click through these elements, looking for new categories on each new page until we hit no more categories, ie. all leaves and the tree is populated. I have much of this already written. My issue arises when trying to iterate through my elements list. I currently try to populate the tree depth-first,

Tree with no duplicate children

问题 Using anytree I produced such tree: A ├── B │ └── C │ └── D │ └── F └── B └── C └── E └── G Is there a way to remove all duplicate children and turn it into the tree below (recursive for children at all possible levels)? A └── B └── C ├── D | └── F └── E └── G Edit: What I am trying to achieve is a tree of all links on a website. So everything between slashes would become a child: .../child/... (second slash is optional). The above is just a representation of my problem, but I hope it's clear
