PySimpleGUi: Unable to complete operation on element with key 0

问题

I'm creating a program that asks the user to guess a certain number that the computer will draw. In the tutorial I'm following to make this program, the tutor uses PySimpleGUI to create an interactive window. This is the program code:

  1. import random
  2. import PySimpleGUI as sg
  4. class GuessNumberSimulator():
  5.     def __init__(self):
  6.         self.random_value = 0
  7.         self.min_value = 1
  8.         self.max_value = 60
  9.         self.number_chances = 10
  11.     def Start(self):
  12.         layout = [
  13.             [sg.Text('Your guess', size=(20,0))],
  14.             [sg.Input(size=(18,0), key='GuessValue')],
  15.             [sg.Button('Guess!')],
  16.             [sg.Output(size=(20,10))]
  17.         ]
  18.         # create a window
  19.         self.window = sg.Window('Guess Number Simulator', layout=layout)
  21.         self.GenerateNumber()
  22.         self.RequestNumber()
  23.         try:
  24.             while True:
  25.                 # receive the values
  26.                 self.event, self.values = self.window.read()
  27.                 self.guess_value = self.values['GuessValue']
  28.                 if self.event == 'Guess!':
  29.                     while self.number_chances != 0:
  30.                         if int(self.guess_value) > self.random_value:
  31.                             print(f'\033[1;32mA little less! (Number of chances: {self.number_chances})\033[m')
  32.                             self.number_chances -= 1
  33.                             self.RequestNumber()
  34.                         elif int(self.guess_value) < self.random_value:
  35.                             print(f'\033[1;31mA little more! (Number of chances: {self.number_chances})\033[m')
  36.                             self.number_chances -= 1
  37.                             self.RequestNumber()
  38.                         if int(self.guess_value) == self.random_value:
  39.                             self.try_again = False
  40.                             print(f'\033[1;34m🎉🎉🎉 CONGRATULATIONS! The number chosen is {self.random_value}! You´re right! 🎉🎉🎉\033[m')
  41.                             break
  42.                         if self.number_chances == 0:
  43.                             print(f'\033[1;35m😢😢😢 What a shame! Your chances are over! The number chosen was {self.random_value}! Better luck next time!\033[m')
  44.         except:
  45.             print('\033[1;031mPlease insert only integer numbers!\033[m')
  47.     def RequestNumber(self):
  48.         self.guess_value = input('Guess any number: ')
  50.     def GenerateNumber(self):
  51.         self.random_value = random.randint(self.min_value, self.max_value)
  53. Guess1 = GuessNumberSimulator()
  54. Guess1.Start()

When I try to run the program, a PySimpleGUI window pops up with this message:

Unable to complete operation on element with key 0. You cannot perform (such as calling update) on an Element until window.read() is called or finalize=True when Window created. Adding a "finalize=True" parameter to your Window creation will likely fix this.

This is a print of the error message:

I tried to check which key the problem was talking about. I tried changing the value of key='GuessValue' to 1, thinking this was the key cited by the error message, but the same message came up. I expected to see the PySimpleGUI interactive window working, but to no avail. The program is running fine in the terminal, but the interactive window doesn't even appear when I try to use the PySimpleGUI in the source code. I tried putting finalize=True" in both self.window = sg.Window('Guess Number Simulator', layout=layout, finalize=True) and self.event, self.values = self.window.read(finalize=True), but the PySimpleGUI window doesn't show anything anymore, it goes blank and doesn't work.

Here is the translated code:

  1. 找不到代码中的异常。要使用 GUI，不应同时使用控制台输入或输出。
  3. 修订后的代码

I've translated the code for you.

Didn't find the exception for your code. To work with a GUI, you should not use console input or output at the same time.
