Idlelib tkinter syntax highlighting reset/update/removal

I am making an IDE that uses the idlelib percolator and colordelegator for syntax highlighting. In my special text widgets init function it runs:

        self.cdg.tagdefs["MYGROUP"] = {"foreground": tag_mygroup, "background": "#FFFFFF"}
        self.cdg.tagdefs["COMMENT"] = {"foreground": tag_comment, "background": "#FFFFFF"}
        self.cdg.tagdefs["KEYWORD"] = {"foreground": tag_keyword, "background": "#FFFFFF"}
        self.cdg.tagdefs["BUILTIN"] = {"foreground": tag_builtin, "background": "#FFFFFF"}
        self.cdg.tagdefs["STRING"] = {"foreground": tag_string, "background": "#FFFFFF"}
        self.cdg.tagdefs["DEFINITION"] = {"foreground": tag_definition, "background": "#FFFFFF"}
        self.cdg.tagdefs["CLASS"] = {"foreground": tag_class, "background": "#FFFFFF"}
        ip.Percolator(self.text).insertfilter(self.cdg)

This gives the text widget syntax highlighting as it is supposed to. I want to allow the user to change the color codes in the settings file and then reset/update or remove and then reapply the syntax highlighting with the new colors. The problem is that when I try to remove the highlighting with ip.Percolator(self.text).removefilter(self.cdg) it gives the error:

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/tkinter/__init__.py", line 1892, in __call__

    tk.call("rename", w, self.orig)
_tkinter.TclError: can't rename to ".!ultra_text.!text_orig": command already exists

Any ideas on how to remove the syntax highlighting?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
