Question

我正在编写一个密码生成应用程序，该应用程序具有多个框架，一个框架生成一个伪随机密码，另一个框架显示并保存它。但是我无法弄清楚在按下pick()时如何分配getBtn的返回值，因此以后可以在txt2.insert('1.0',txtfin)中显示它，因为据我所知您必须将pick(txtfin)分配给某些内容（例如newvar = pick(txtfin)）以包含返回的值。事实是，密码生成工作正常，并显示在txt.insert('1.0',txtfin)中，但这只能起作用，因为它位于pick()函数内部。我需要将返回的pick()值分配给一个变量的原因是因为我想稍后将其显示在另一个框架中。

任何朝着正确方向的帮助或推动将不胜感激。我已经在这个问题上停留了一段时间。如果我做错了什么，请放心，我是新手。

from tkinter import *
from random import sample

def show_frame(frame):
    frame.tkraise()

window = Tk()
window.geometry("375x108")

img = PhotoImage(file='logo.gif')

frame1=Frame(window)
frame1.grid(row=0, column=0, sticky='nsew')

#Password code
imgLbl = Label(frame1, image=img)
txt = Text(frame1, width=29, height = 1)
getBtn = Button(frame1)
resBtn = Button(frame1)
txt2 = Text(frame1, width=20, height = 1)

#Geometry:
imgLbl.pack(side = LEFT)
txt.place(x = 122, y = 15)
getBtn.pack(side = LEFT, padx = 5, pady = 15)
resBtn.pack(side = LEFT, padx = 5, pady = 15)
txt2.place(x = 122, y = 70)

#Static Properties:
window.title('Random Password Generator')
window.resizable(0,0)
getBtn.configure(text = 'Generate A New Password')
resBtn.configure(text = 'Reset')

#Initial Properties:
resBtn.configure(state=DISABLED)

#Dynamic Properties:

txtfin = ''

def pick(txtfin):
    passlen = sample(range(12,16),1)
    plnum = passlen[0]
    
    nums = sample(range(0,62),plnum)
        
    for i in nums:
        txtfin = txtfin + alpha[i]
    txt.insert('1.0',txtfin)
    getBtn.configure(state=DISABLED)
    resBtn.configure(state=NORMAL)
    return txtfin


def reset():
    txt.delete('1.0', END)
    getBtn.configure(state=NORMAL)
    resBtn.configure(state=DISABLED)
    
getBtn.configure(command=lambda:pick(txtfin))
resBtn.configure(command=reset)


txt2.insert('1.0',txtfin)

show_frame(frame1)

#Sustain window:
window.mainloop()

当在tkinter中单击按钮时，如何分配函数返回变量的值？
