问题描述
我对 Python 还很陌生，我有一份需要使用图、顶点和边概念的大学作业，但是我正在努力研究如何正确实现这一点。
以下是所需工作的描述：
a) 在 Vertex 中，创建一个 Station 子类，以包含该站的 id 和位置（以十进制度数表示） 地球表面的物体。
b) 从 lisbon.stations.csv 中的数据集创建 Station 对象列表。
c) 在 Edge 下，创建一个 Edge_line 子类，以包含连接所在的线。
d) 从同一数据集创建“Edge_line”对象列表。
e) 创建一个图结构。
示例：
Import myplotlib.myplot as plt
fig = plt.figure()
plt.line(x,y,c=color)
以下是我目前的代码。我想我设法做到了 c) 点，但希望您能在审查整个代码方面得到帮助。
此外，请在下方找到用于这项工作所需的 CSV 文件。
