python只是重新启动并且根本不运行程序

Question

任何人都可以帮我这个吗？我使用生成python代码的wxformbuilder创建了一个gui。然后我创建了一个单独的代码，说明它应该如何工作。

这第一个代码仅适用于gui。

Q15 = 'Q15'
Q16 = 'Q16'
Q17 = 'Q17'
Q18 = 'Q18'
Q19 = 'Q19'
Q20 = 'Q20'

    x = 0
    def __init__(self, parent):
        frmQuestions.__init__(self,parent)
        self.txtQ.SetLabel('')

    def OnNext(self, event):
        self.x = self.x + 1
        if (self.x==1):

        print self.x

    def OnShowResults(self, event):
        results.Show()

    def OnExit(self, event):
        self.Destroy()



class Results(frmResults):
    def __init__(self, parent):
        frmResults.__init__(self,parent)

    def OnGoBack(self, event):
        self.txtA.SetLabel('')
        self.txtB.SetLabel('')

        self.Hide()


app = wx.App(False)

questions.Show()


app.MainLoop()

每次我在rpi上运行它。 python shell只是一直显示------------------------------- restart ------------- ------------和gui根本没有出现。我只想知道代码有什么问题。

我也在Windows上创建了代码，我在rpi上复制了两个python文件。在Windows上它工作正常。我真诚地感谢你，我只是一个学生和一个新手，所以我无法指出我的代码有什么问题。谢谢:)）））

Answer 1

您是通过./myscript.py运行的吗？如果是这样，您需要将解释器添加到顶部。第一行应该是：

#!/usr/bin/env python

或类似的东西，以便它知道使用哪个解释器。

我知道这不是问题，但说实话，我更关心你的实际计划。例如，您可以将它们全部创建为dict并更新全局变量，而不是编写多个连续的QN = "QN"。例如：

tmp = ["Q{}".format(i+1) for i in range(20)]
globals().update(dict(zip(tmp, tmp)))

这要容易得多。或者，更好的是，你可以用dict的形式将数字映射到你想要的字符串，这样整个事情就可以重写为：

#!/usr/bin/env python
from noname import *
from wx import *

tmp = ["Q{}".format(i+1) for i in range(20)] # Create a list of "Q1"..."Q20"
vars = dict(enumerate(tmp, 1)) # { 1 : "Q1", 2 : "Q2", ... 20 : "Q20" }

class Questions(frmQuestions):
    def __init__(self, parent):
        self.x = 0 # Made this an instance variable
        frmQuestions.__init__(self,parent)
        self.txtQ.SetLabel('')

    def OnNext(self, event):
        self.x = self.x + 1
        if self.x in vars:
            self.txtQ.SetLabel(vars[self.x]) # significantly simplified
        print(self.x)

    def OnShowResults(self, event):
        results.show()

    def OnExit(self, event):
        self.Destroy()

class Results(frmResults):
    def __init__(self, parent):
        frmResults.__init__(self,parent)

    def OnGoBack(self, event):
        for _ in [self.txtA, self.txtB, self.txtC, self.txtD]:
            _.SetLabel('')
        self.Hide()

app = wx.App(False)
results = Results(None)
questions = Questions(None)
questions.Show()


app.MainLoop()
