tk 如何添加jpg?
pickle文件？
pickle?

label_1 = tk.Label(window, bg='yellow', width=30, height=2, text='empty').pack()

Exception in Tkinter callback Traceback (most recent call last): File "D:\torchenv\lib\tkinter\__init__.py", line 1883, in __call__ return self.func(*args) File "E:/Practice/python_work/Jupyter/Tkinter/tkinter_pycharm/Radiobutton.py", line 14, in print_selection label_1.config(text='you have selected' + selected_var.get()) AttributeError: 'NoneType' object has no attribute 'config'

label_1 = tk.Label(window, bg='yellow', width=30, height=2, text='empty')
label_1.pack()

    if (var1 == 1) & (var2 == 0):label_1.config(text='Only Python')

我是按照“安装”顺序从上到下写程序的

莫烦是按照结构从上到下写程序的，写了结构以后，再回过头往结构里面填充内容
