我无法将数据输入从一个类传递到另一个类，我似乎无法使全局函数工作。我需要帮助的部分是在最后一个函数中，但它只有在你拥有整个代码时才有效。

如果要使用全局变量，则需要执行以下操作：
var1 = <some value>
var2 = <some other value>
s1 = <yet another value here>
# then create your classes
class Whatever(tk.whatever_you_want):
def __init__(self, arg1, arg2, whatever_arg):
global var1 #whis tells the function to use the variable you defined already in the module scope
local_var_1 = var1 * 100 #
当然，也许你不知道这一点，全局变量通常被认为是不好的，但我认为这对你来说并不重要。当你修改和阅读来自waaay太多地方的变量来跟踪时，这很重要，但我不确定你是在构建那么大的脚本。
