问题描述
限时送ChatGPT账号..我想在 tkinter 中创建很多小部件.我目前为此使用了很多代码.有没有办法总结代码?但是，我仍然希望能够捕获每个小部件的价值.编号增加到 200...非常感谢！
I would like to create a lot of widgets in tkinter. I am currently using a lot of code for this. Is there a way to summarise the code? However, I would still like to be able to capture the value of each widgets. The numbering goes up to 200... Thanks a lot!

我定义了一个字典，但问题太多了.
I defined a dict, but i get too much issues.

推荐答案
从变量中删除前缀，然后以前缀为键创建字典.
Remove the prefix from your variables, and then create dictionaries instead with the prefix as the key.
例如，self.A1_choice_rubbing_marks 变成 self.choice_rubbing_marks[A1"] 等
对每个变量都这样做.在你弄清楚如何用简单的循环来做之前，不要尝试使用字典推导式.
Do that for each variable. Don't try to use dictionary comprehensions until you figure out how to do it with simple loops.
例如:
self.choice_rubbing_marks = {}
self.rubbing_marks_Type = {}
self.Menu_rubbing_marks = {}
self.Frame_measure = {}
for i in range(200):
key = f"A{i}" # => A0, A1, ..., A199
self.rubbing_marks_Type[key] = tk.StringVar(self.A_Frame_measurevalue='')
self.Frame_measure[key] = tk.StringVar()
self.choice_rubbing_marks[key] = ['No', 'Yes']
self.rubbing_marks_Type[key].set('') # set the default option
self.Menu_rubbing_marks[key] = tk.OptionMenu(
self.A_Frame_measure,
self.rubbing_marks_Type[key], *self.choice_rubbing_marks[key],
command=self.show_rubbing_marks_borders
)
self.Menu_rubbing_marks[key].config(width=4)
self.Menu_rubbing_marks[key].grid_forget()
