我对 python 比较陌生，我在命名空间方面遇到了一些问题.

I am relatively new to python and i am experiencing some issues with namespacing.

class a: def abc(self): print "haha" def test(self): abc() b = a() b.test() #throws an error of abc is not defined. cannot explain why is this so

推荐答案

由于 test() 不知道谁是 abc，所以 msg NameError:全局名称 'abc' 未定义 您看到应该在调用 b.test() 时发生(调用 b.abc() 很好)，更改它:

Since test() doesn't know who is abc, that msg NameError: global name 'abc' is not defined you see should happen when you invoke b.test() (calling b.abc() is fine), change it to:

class a: def abc(self): print "haha" def test(self): self.abc() # abc() b = a() b.abc() # 'haha' is printed b.test() # 'haha' is printed
