我正在创建一个允许用户在回合制系统中对抗敌人的系统，但是在三周之后，我遇到了一系列问题。在遇到这个新问题时，我担心自己会变得更糟，而不是更好，所以我会感激任何帮助。
该计划应该：
from tkinter import * #needs for GUI
import random #needed for randomisation of options
def YNquestion(questionString): #putting the code necessary for the GUI into a function allows it to be called every time the quesiton is asked
global answer #allows the vaiable to be used anywhere in the program
def yes_command(): #called by the GUI to change the variable when the button is clicked
answer.set('yes') #.set allows this to exit the GUI as it is a gloabal variable
window.destroy() #closes the GUI window so the program does no become stuck
def no_command(): #similar to the procedure above but sets the variable to 'no'
answer.set('no')
window.destroy()
window = Tk() #creates GUI window
yes_no_label = Label(window, text=questionString) #sets the label text within this GUI specified as 'window', set to the string specified when called so this can be used in multiple ways such as in tic tac toe or setting gender of character
yes_no_label.grid(row=0, column=1) #sets a place for the label to be displayed on the GUI
answer=StringVar() #needed when running Tkinter with multiple Tk instances to allow variable to be used outside of program (value cannot be assigned within tkinter).
YESbutton = Button(window, text="Yes", fg='green', command = lambda :yes_command()) #sets the button with test and colour deatils, as well as what happens when pressed.
YESbutton.grid(row=1, column=0) #sets button location
NObutton = Button(window, text = 'No', fg = 'red', command= lambda :no_command()) #same as for button above
NObutton.grid(row=1, column=2)

这个当前代码在赋值之前提出了变量引用的新问题，即使不是这种情况。
感谢您的帮助。
答案 0 :(得分：1)
def enemies(enemy)
if enemy == 'goblin':
global eHealth
eHealth = 10
return eHealth
eHealth = enemies(enemy)
进行了这些更改并且有效。看起来代码还有其他一些问题。但是应该解决已发布的问题
