我如何从 python 中的文本文件中读取我的数据集并在其上应用矩阵

Question

I want to apply adjacent matrix that take data from the file text and apply matrix then the output will be zeros and ones

this is my code of the dataset stored in file text

mylist= ['T','C','A','G']

with open("codon2.txt", "w") as f_out:
    for i in range(0,len(mylist)):
         for j in range(0,len(mylist)):
            f_out.write('\n')
            for k in range(0,len(mylist)):
             f_out.write(mylist[i]+mylist[k]+mylist[j])
             f_out.write(' ')

I totally assumed everything, hope this is what you are looking for. Following code, will set adjacency matrix (firstly containing only 0's), then convert 0's to 1's for adjacent nodes.

class Graph:
    def __init__(self, numNodes):
        self.adjacencyMatrix = []
        for i in range(numNodes): 
            self.adjacencyMatrix.append([0 for i in range(numNodes)])
        self.numNodes = numNodes

    def addEdge(self, start, end):
        self.adjacencyMatrix[start][end] = 1


# random example
edges_list = [[1, 2], [0, 1], [2, 3]]

# assuming number of nodes is 4
graph = Graph(4)

# converts 0's to 1's for adjacent nodes
for i in edges_list:
    graph.addEdge(i[0], i[1])

with open("codon2.txt", "w") as f_out:
    for i in graph.adjacencyMatrix:
        for j in i:
            f_out.write(str(j))
        f_out.write('\n')
