[英]How to get the reference of one variable of one class in another class in python?
[英]How to reference a class variable in python
我似乎无法让类读取它继续NameError: global name 'import_1' is not defined
的活字典NameError: global name 'import_1' is not defined
我正在使用本指南:
http://www.ibiblio.org/g2swap/byteofpython/read/class-and-object-vars.html
这是代码:
class test_imports:#Test classes remove
alive = {'import_1': True, 'import_2': True};
def halt_listener(self, control_Queue, thread_Name, kill_command):
global alive
while True:
isAlive = control_queue.get()
if isAlive == kill_command:
test_imports.alive[thread_Name] = False;
return
def import_1(self, control_Queue, thread_Number):
print ("Import_1 number %d started") % thread_Number
t = Thread(target=test_imports.halt_listener, args=(control_Queue, 'import_1', 't1kill'))
count = 0
global alive
run = test_imports.alive[import_1];
while run:
print ("Thread type 1 number %d run count %d") % (thread_number, count)
count = count + 1
print ("Test Import_1 ", run)
run = test_Imports.alive['import_1'];
print ("Killing thread type 1 number %d") % thread_Number
我错过了什么? 多谢你们!
你忘了引号:
run = test_imports.alive['import_1']
请注意,在class内部不需要使用global
,其次是内部方法,您可以使用self
来引用类以及实例属性:
run = self.alive['import_1']
