“变量"可能未定义或从星导入定义:tkinter [英] "variable" May be undefined or defined from star imports: tkinter

问题描述

我正在尝试为 gui 制作一个简单的轮廓，但我收到了警告"variable" 可能未定义或从 star 导入定义:tkinter 用于我的所有变量.

I'm trying to make a simple outline for a gui, and I'm getting the warning "variable" May be undefined or defined from star imports: tkinter for all of my variables.

这是我的代码:

from tkinter import *

class myApp :
    def __init__(self, gui,) :
        self.root = gui
        self.bframe = Frame(self.root)  # Create a container Frame at bottom
        self.bframe.pack(side=BOTTOM)
        self.xlabel = Label(self.root, text="Item ID")  # Create the Label
        self.xlabel.pack(side=LEFT)
        self.xentry = Entry(self.root, bd=5)  # Create the Entry box
        self.xentry.pack(side=LEFT)
        self.xentry.bind('<Return>', self.showStockItem)
        self.xentry.focus_set()  # Set focus in the Entry box
        self.xopen = Button(self.root, text="Show", command=self.showStockItem) # Create the open Button
        self.xopen.pack(side=LEFT)
        self.xquit = Button(self.bframe, text="Quit", command=self.quitit) # Create the quit Button
        self.xquit.pack(side=BOTTOM)
        return

gui = Tk()
gui.title("Travel")
app = myApp(gui)
gui.mainloop()

推荐答案

from tkinter import *

在这一行中，您从 tkinter 导入所有内容.不建议这样做，因此 linter 会警告您.但如果你真的想这样做，也没关系，直接无视就好.

In this line, you import everything from tkinter. This is not recommended, so linter will warn you. But if you really want to do this, it's OK, just ignore it.

为了更好，您应该明确导入您需要的内容.例如:

To be better, you should explicitly import what you need. For example:

from tkinter import Tk, Label, Frame, Entry, Button
