NameError：没有定义全局名'classObject'PYTHON

Question

我有一个类master.py与Glade有关的Gui。我有一个带有事件的按钮。 所有我想要的是从另一个类另一个python文件中调用另外两个方法，但NameError：全局名称'Airmong'未定义 错误被抛出。

这些文件位于相同的文件夹！ master.py文件包含：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 
from gi.repository import Gtk 
from airmong import Airmong 
class Handler: 
    airmonObj=Airmong(); 
    def airmon_clicked(self, button): 
     airmonObj.startAirmong() 
builder = Gtk.Builder() 
builder.add_from_file("master.glade") 
builder.connect_signals(Handler()) 

window = builder.get_object("window1") 
window.connect("delete-event", Gtk.main_quit) 
window.show_all() 
Gtk.main() 

airmong.py文件包含：

#!/usr/bin/python 
# -*- coding: utf-8 -*- 
class Airmong: 
    def __init__(self): 
     pass 
    def stopAirmong(self): 
      result = subprocess.check_call(['airmon-ng','stop' ,'wlan0mon']) 
      if result == 0: 
        print "Success stopping airmong" 
      else: 
        print "CAN'T stop airmong" 


    def startAirmong(self): 
     result=subprocess.check_call(['airmon-ng','start','wlan0']) 
     if result == 0: 
        print "Success starting airmong" 
     else: 
        print "CAN'T start airmong" 

我在做什么错误非常感谢

错误：

Traceback (most recent call last): 
File "./master.py", line 9, in airmon_clicked 
airmonObj.startAirmong(); 
NameError: global name 'airmonObj' is not defined 

Answer 1

代码中出现多处错误：

Master.py：

1）Line4在功能line8缩进身体变化内容from airmong.py import Airmong为from airmong import Airmong

2）。示例代码的功能可能如下。

class Handler: 
    airmonObj=Airmong(); 

    def airmon_clicked(self, button): 
     airmonObj.startAirmong() 

airmong.py：

3）line3

前4 class关键字删除空间）为您初始化功能补充身体。示例可以如下。请在class之前关注关键词

class Airmong: 
    def __init__(self): 
     pass 

一步一步修复所有语法错误。 `airmong.py`的
