如何从 PySimpleGUI 列表框中所选值的元组列表中返回第二项

如何解决如何从 PySimpleGUI 列表框中所选值的元组列表中返回第二项

我想点击一个列表框值（属性列表）并显示相关的诗句（大列表元组中的第二个值）。我在将一个列表与第二个列表同步时遇到问题。不过，可能更像是 Python 问题而不是 PySImpleGUI 问题。

import PySimpleGUI as sg

biglist = [('Abundant Life','John 10:10'),('Angels','Psalm 103:20'),('Boldness','Proverbs 28:1')]

attriblist = []

for idx,(promise,verse) in enumerate(biglist):    
    attriblist.append(str(promise))
  
sg.theme('Tan Blue')

layout = [[sg.Text('Pick an attribute and see verse of promise.')],[sg.ListBox(attriblist,size=(20,20),key='-LIST-',enable_events=True)],[sg.Multiline(size = (58,5),key = '_multiline_',autoscroll = False,disabled=True)],[sg.Button('Exit')]]

window = sg.Window("God's Promises",layout)

while True: 

    event,values = window.read()
    if event in (sg.WIN_CLOSED,'Exit'):
        break
    for index,verse in enumerate(values['-LIST-']):
        #print(verse)
        for idx,verse) in enumerate(biglist):
            window['_multiline_'].update(verse)
            

window.close()

解决方法

这个怎么样，

import PySimpleGUI as sg

biglist = [
    ('Abundant Life','John 10:10'),('Angels','Psalm 103:20'),('Boldness','Proverbs 28:1')
]
attrib_dict = {key:value for key,value in biglist}
attrib_list = sorted(attrib_dict.keys())

sg.theme('Tan Blue')
sg.set_options(font=('Courier New',12))

layout = [
    [sg.Text('Pick an attribute and see verse of promise.')],[sg.Listbox(attrib_list,size=(20,10),key='-LIST-',enable_events=True),sg.Multiline(size = (60,key = '-MULTILINE-',autoscroll = False,disabled=True)],[sg.Button('Exit')]]

window = sg.Window("God's Promises",layout,finalize=True)
window['-MULTILINE-'].Widget.configure(spacing1=1)

while True:

    event,values = window.read()
    if event in (sg.WIN_CLOSED,'Exit'):
        break
    elif event == '-LIST-':
        selection = values[event][0]
        window['-MULTILINE-'].update(value=attrib_dict[selection])

window.close()
