python导入文件但图像无法识别

Question

我创建了一个带有下拉菜单的 python 文件。当我选择选项一时，它会导入另一个 python 文件，其中有一个复选按钮和画布中的图片。文件和图片都位于同一文件夹中。代码导入文件导入画布和检查按钮，但我收到错误消息说图像“pyimage1”不存在。如果我单独运行第二个文件，它确实显示复选按钮和图像，没有错误。当导入 python 文件时，图像不再被识别，或者我做错了什么？有什么解决方法吗？主要程序：from tkinter import *root = Tk()root.geometry('1560x750')canvas=Canvas(root)canvas.config(width=1000, height=1560, bg='light grey')canvas.grid(row=1,column=3, rowspan=1550,ipadx=1300,ipady=750,sticky=NW)def option_number(x):    if x == "one":        import part2variable = StringVar()variable.set("options")w = OptionMenu(canvas, variable, "one", "two",command = option_number)w.config(width=15, height=1,bg='blue')w.place(x=400,y=100)root.mainloop()要导入的文件：from tkinter import *root = Tk()root.geometry('1560x750')canvas=Canvas(root)canvas.config(width=1000, height=1560, bg='light grey')canvas.grid(row=1,column=3, rowspan=1550,ipadx=1300,ipady=750,sticky=NW)button = Checkbutton(canvas).place(x=170, y=230)AND_gate=PhotoImage(file='AND.png') #set up variables for and_gatelabelimage_and = Label(canvas, image=AND_gate).place(x=200,y=200)root.mainloop()更新了导入函数的代码：from tkinter import *root = Tk()root.geometry('1560x750')canvas=Canvas(root)canvas.config(width=1000, height=1560, bg='light grey')canvas.grid(row=1,column=3, rowspan=1550,ipadx=1300,ipady=750,sticky=NW)def option_number(x):    if x == "one":        from part1 import import_defvariable = StringVar()variable.set("options")w = OptionMenu(canvas, variable, "one", "two",command = option_number)w.config(width=15, height=1,bg='blue')w.place(x=400,y=100)root.mainloop()

Answer 1

这是我知道如何在 tkinter 中导入文件和函数的方法，不确定这是否是正确的方法，但看看我对这两个文件所做的更改

main.py:

from tkinter import *

from function import import_def

root = Tk()

root.geometry('1560x750')

canvas=Canvas(root)

canvas.config(width=1000, height=1560, bg='light grey')

canvas.grid(row=1,column=3, rowspan=1550,ipadx=1300,ipady=750,sticky=NW)

def option_number(x):

    if x == "one":

        import_def()

variable = StringVar()

variable.set("options")

w = OptionMenu(canvas, variable, "one", "two",command = option_number)

w.config(width=15, height=1,bg='blue')

w.place(x=400,y=100)

root.mainloop()

和函数.py：

from tkinter import *

def import_def():

    root = Toplevel()

    root.geometry('1560x750')

    canvas2 = Canvas(root)

    canvas2.config(width=1000, height=1560, bg='red')

    canvas2.grid(row=1, column=3, rowspan=1550, ipadx=1300, ipady=750, sticky=NW)

    button = Checkbutton(canvas2).place(x=170, y=230)

    AND_gate=PhotoImage(file='sad songs.jpg') #set up variables for and_gate

    labelimage_and = Label(canvas2, image=AND_gate).place(x=200,y=200)

    root.mainloop()
