我目前正在做gcse计算机科学，对于我目前的工作，我必须制作一个人口模型。我已经制作了几个输入框，并希望能够存储然后获取该信息以在另一个窗口上打印，然后在计算中使用它。请有人帮助我获取要打印的值吗？我尝试了多种方法而没有太多运气。我道歉，我所做的其他一些代码可能不对！当我尝试运行我的程序时，错误说“问题1”未定义＆＃39;在我现在的代码中尝试获取要打印的信息。

答案 0 :(得分：0)
首先，按钮的command选项需要一个函数，因此在编写command=entQuestion7.get()时代码是错误的，它应该是command=entQuestion7.get。但即便如此，也不会发生任何事情，因为你不会对价值做任何事情。
其次，我认为为人口模型创建一个类而不是一个函数应该更容易和更整洁：
import tkinter
class PopulationModel:
def __init__(self):
self.window = tkinter.Tk()
# question 1
tkinter.Label(self.window, text="What is the population number of juveniles?").grid(row=0, column=0)
# create an entry widget for question 1
self.entQuestion1 = tkinter.Entry(self.window)
# place the widget into the window
self.entQuestion1.grid(row=1, column=0)
# default answers
self.Question1 = ""
# create a button widget to check answers ############ QUESTION 1 ###############
tkinter.Button(self.window, text="Set Value", command=self.get_1).grid(row=1, column=1)
# create a button widget to display generation 0 values
tkinter.Button(self.window, text="Display Generation 0 values",
command=self.displayvalues).grid(row=2, column=0, columnspan=2)
self.window.mainloop()
def get_1(self):
""" get answer 1 """
self.Question1 = self.entQuestion1.get()
def displayvalues(self):
""" display the initial values """
top = tkinter.Toplevel(self.window)
tkinter.Label(top, text="DISPLAY GENERATION 0 VALUES").grid(row=0)
tkinter.Label(top, text="Answer 1: %s" % self.Question1).grid(row=1)
