Python – 我可以访问给我打电话的对象吗?
作者:互联网
如果我有这个:
class A:
def callFunction(self, obj):
obj.otherFunction()
class B:
def callFunction(self, obj):
obj.otherFunction()
class C:
def otherFunction(self):
# here I wan't to have acces to the instance of A or B who call me.
...
# in main or other object (not matter where)
a = A()
b = B()
c = C()
a.callFunction(c) # How 'c' know that is called by an instance of A...
b.callFunction(c) # ... or B
尽管存在设计或其他问题,但这只是一个探究性思维的问题.
注意:必须在不更改otherFunction签名的情况下完成此操作
解决方法:
如果这是出于调试目的,您可以使用inspect.currentframe():
import inspect
class C:
def otherFunction(self):
print inspect.currentframe().f_back.f_locals
这是输出:
>>> A().callFunction(C())
{'self': <__main__.A instance at 0x96b4fec>, 'obj': <__main__.C instance at 0x951ef2c>}
