How can I write code that searches for each '\n' newline character in a string and then adds an asterisk after it? I don't want to use 'str.split()' [closed]

I would like to write a program that searches for each \n newline character in a string and then adds an asterisk just after that. For example, a string like this:

string= 'we will do it\nwe can do it\nwe want to do it\nwe have to do it'

The result should look like this:

*we will do it
*we can do it
*we want to do it
*we have to do it

I tried the code below which splits the string at where '\n' occurs into a list, then I used a for loop to add the asterisks:

string= 'we will do it\nwe can do it\nwe want to do it\nwe have to do it'
new_string = string.split('\n')
for i in new_string:
    print("*"+i)

It worked perfectly but I would like to use another method which is: to write code that searches for each \n newline character in the string and then adds the star just after that. (for learning purposes)

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() ...
