python-3.x - 如何将动态参数作为参数传递
问题描述
我有以下代码：

self.ip_word.grid(row=0,sticky=E)
self.ip_path_field = Entry(master)
self.ip_path_field.grid(row=0,column=1,sticky=W)
self.op_word = Label(master,text="Output Path")
self.op_word.grid(row=2,sticky=E)
self.op_path_field = Entry(master)
self.op_path_field.grid(row=2,column=1,sticky=W)
self.filename_word=Label(master,text="Output Filename ")
self.filename_word.grid(row=4,sticky=E)
self.filename =Entry(master)
self.filename.grid(row=4,column=1,sticky=W)
self.Submit = Button(master,text="Submit",fg="black",bg="white",command=self.Scraper(ip_path_field,op_path_field,filename) )
self.Submit.grid(row=5,columnspan=2)

现在我想做的是：
我想将变量 ip_path_field,op_path_field,filename 作为参数传递给名为scraper的函数。现在 ip_path_field,op_path_field,filename 都是用户输入，而不是硬编码字符串。现在，每当我运行以下代码时，我都会打开 GUI，每当我在所需的编辑框中提供我的输入并按下提交按钮时，我都会收到以下错误名称“ip_path_field”未定义。我使用此代码的目的是将用户定义的文件路径传递给上面代码中定义的名为scraper () 的函数。
解决方案
您需要创建一个获取值的回调，然后将它们传递给执行该工作的函数。
例子：
class GUI:
def __init__(self,master):
...
self.Submit = Button(..., command=self.handle_submit)
...
def handle_submit(self):
ip_path = self.ip_path_field.get()
op_path = self.op_path_field.get()
filename = self.filename.get()
self.Scrapper(ip_path_field,op_path_field,filename)
