Question

我正试图将一个班级的假 function功能进入另一个文字。这使我有以下错误:

AttributeError:  module  object has no attribute  functionName

The function is present in a class and is accessed via classname.functionName() call. Is there anything that I am missing ?

- 更新

我的法典是:

(program.py)
import ImageUtils
import ...
class MyFrame(wx.Frame):
...
    ImageUtils.ProcessInformation(event)


(ImageUtils.py)
import statements... 
class ImageUtils(threading.Thread):
    def ProcessInformation(self, event):
        self.queue.put(event)

Thus, the error is : AttributeError: module object has no attribute ProcessInformation So, do I have to make this second script a module only ?

Answer 1

课堂内的功能称为一种方法。你们可以从另一个单元进入。

import module
module.Classname.method

However, unless that method is a special kind of method call a staticmethod or classmethod, you won t be able to call it with module.Classname.method().

相反,你需要证明:

inst=module.Classname(...)

之后将这种方法从班级改为:

inst.method()

您收到错误的原因

AttributeError:  module  object has no attribute  function_name

is because module does not have a variable named function_name in its namespace. It does have a variable named Classname however. Meanwhile, Classname has a variable named function_name in its namespace. So to access the method, you need to "burrow down" to function_name by performing two attribute lookups: module.Classname.function_name.

Answer 2

可以证明,你试图将这一功能从单元中而不是从该类别中调取。我建议你做这样的事情:

from my_module import my_class

my_class.my_function(...)
# bla bla bla

http://www.un.org。我认为,“沙尔”不会让你以职能的名义使用“-”。

Answer 3

您不妨尝试dir(,以便了解该职能是否与你预期的实际存在。

缩略语模块:

>>> import math
>>> dir(math)
[ __doc__ ,  __file__ ,  __name__ ,  acos ,  asin ,  atan ,  atan2 ,  ceil ,  cos ,  cosh ,  degrees ,  e ,  exp ,  fabs ,  floor ,  fmod ,  frexp ,  hypot ,  ldexp ,  log ,  log10 ,  modf ,  pi ,  pow ,  radians ,  sin ,  sinh ,  sqrt ,  tan ,  tanh ]
