Python: NameError: global name 'foobar' is not defined
提问by skyeagle
I have written the following class:
我编写了以下课程：
class myClass(object):
def __init__(self):
pass
def foo(self, arg1, arg2):
pp = foobar(self, arg1, arg2)
if pp:
return 42
else
return -666
def foobar(self, arg1, arg2):
if arg1 == arg2:
return 42
else:
return None
The logic is nonsensical - ignore it. What I am trying to so is to call an instance method from another instance method - and I am getting a NameError. I originally thought that this was due to foo()calling foobar()before it had been defined - but switching the order of the function definitions in the script made no difference.
逻辑是荒谬的 - 忽略它。我想要做的是从另一个实例方法调用一个实例方法 - 我得到了一个NameError. 我最初认为这是由于在定义之前foo()调用foobar()- 但切换脚本中函数定义的顺序没有任何区别。
Does anyone what's causing this error, and how to fix it?
有没有人是什么导致了这个错误，以及如何解决它？

Python doesn't scope code to the local class automatically; you need to tell it to.
Python 不会自动将代码范围限定为本地类；你需要告诉它。
pp = self.foobar(arg1, arg2)
