用Javascript创建购物车

Question

我试图用javascript / jQuery创建购物车。我的问题是我的逻辑在代码中不起作用。查看我的代码。

from try import student

student1 = student("Jimmy", "Business", 3.1, False)
print(student1.name)

这是我的产品列表，我使用javascript尝试获取用户激活“ li”的元素。

C:\Users\User\PycharmProjects\test\venv\Scripts\python.exe C:/Users/User/PycharmProjects/test/try.py

Process finished with exit code 0

现在我有一个购物车，我不知道如何给变量。

<ul class="list-guides row">
