TypeError:'模块对象不可调用' [英] TypeError: 'module object is not callable'
问题描述
嗨
我是Python的新手,在尝试使用另一个文件中的一个类实例化一个对象时,收到了这个错误消息
目录并想知道我做错了什么。
我有一个Step.py类:
class Step(object)
def __init __(self,sName):
"初始化一个新的Step实例"
self.sName = sName
self.depSteps = []
self.remDepSteps = []
self.isCompleted = 0
然后我创建了一个新的同一目录中的文件名为
main.py:
import步骤
a = Step(" magn")
但是下面会产生错误
Traceback(最近一次调用最后一次):
文件" main.py",第3行,in?
a = Step(magn)
TypeError:''module''对象不可调用
如果有人能帮我指点正确的方向,如何解决这个
问题,我将不胜感激。
克里斯
Hi
I am new to Python and have recieved this error message when trying to
instantiate an object from a class from another file within the same
directory and wondered what I have done wrong.
I have a Step.py class:
class Step(object)
def __init__(self, sName):
"Initialise a new Step instance"
self.sName = sName
self.depSteps = []
self.remDepSteps = []
self.isCompleted = 0
Then I have created a new file within the same directory called
main.py:
import Step
a = Step("magn")
The following however generates the error
Traceback (most recent call last):
File "main.py", line 3, in ?
a = Step("magn")
TypeError: ''module'' object is not callable
If anyone could help point me in the right direction, how to fix this
problem it would be much appreciated.

由于您对
名称感到困惑,因此提出了例外情况,即:您有一个名为Step的类。在名为Step.py的模块中。
并且通过导入模块唯一的步骤 python看到的是模块
而不是模块中声明的名称。
要访问模块中定义的名称,你可以这样做:
example1:
import步骤
a = Step.Step(" magn")#它指的是名称步骤。在模块中定义Step
示例2:
来自Step import的
步骤#您直接导入课程(并制作
名称在您的名字空间中可见)
a = Step(magn)

The exception is being raised as you are being confused about the
names ie: you have a class named "Step" in a module named "Step.py" .
And by importing the module the only "Step" python sees is the module
not the names declared within the module.
To access a name defined in the module you can do :
example1:
import Step
a = Step.Step("magn") # It refers the name "Step" defined IN the module "Step"
example 2:
from Step import Step # You directly import the class ( and make the
name visible in your name space)
a = Step("magn")
Also have a look at:

这是因为当你问题导入步骤你实际上导入了
步骤 _module_,而不是步骤。模块里面的课程。
你可以用至少两种方式做到这一点:
------
import步骤
a = Step.Step(" magn")#访问Step模块中的Step类
------
<步骤导入步骤#在当前命名空间中插入Step类
或
------
>
a = Step(magn)
------
This is because when you issue "import Step" you''re actually importing
the "Step" _module_, not the "Step" class inside the module.
You can do this in at least two ways:
------
import Step
a = Step.Step("magn") # access the Step class inside Step module
------
or
------
from Step import Step # insert in the current namespace the Step class
a = Step("magn")

您是否有机会来自java背景?
您的实际问题可以通过以下方式解决:
导入步骤
Step.Step(" magn")
那是因为Step.py是一个模块,而_not_类 - 没有
文件类对应,因为它在例如Java。
Diez
Do you by any chance come from a java-background?
Your actual problem is simply solved by this:
import Step
Step.Step("magn")
That''s because Step.py is a module, and _not_ the class - there is no
file-class-correspondence as it is in e.g. Java.
