在 Python 3.4 中重新加载模块 [英] Reload a Module in Python 3.4
问题描述
我知道这听起来可能是一个非常愚蠢的问题,但无论如何.我用 Python 编写了一个小脚本,并在 shell 中进行了一些更改.通常,在 OS X 计算机(它运行 Python 2.7)上,我只需输入 reload(the_module)
,它就会重新加载我的模块,其中包括我所做的更改.但是,当我在这里重新加载模块时(在 windows python v. 3.4 上),它只是给了我这个:
然后当我输入 imp.reload(my_module)
时,它只是说该函数已被弃用.我似乎无法在任何地方找到新功能(或等效功能)的内容,所以如果有人可以帮助我那就太好了!:)
imp
模块在 Python 3.4 中被弃用,取而代之的是 importlib
模块.来自 imp
模块的文档:><块引用>
自 3.4 版起已弃用:imp
包正在等待弃用支持 importlib
.
所以,你应该从那里使用 reload
函数:
I know this might sound like a really stupid question but whatever. I've made a small script in Python and I've made some changes while in a shell. Normally, on an OS X computer (It's running Python 2.7), I would simply type in reload(the_module)
and it would reload my module that includes the changes that I have made. However, when I am reloading the module here (on windows python v. 3.4), it simply gives me this:
>>> reload(instfile)
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
reload(instfile)
NameError: name 'reload' is not defined
And then when I type in imp.reload(my_module)
, it simply says that the function is deprecated. I can't seem to find what the new function (or it's equivalent) would be anywhere so if someone can help me that would be great! :)
The imp
module was deprecated in Python 3.4 in favor of the importlib
module. From the documentation for the imp
module:
Deprecated since version 3.4: The
imp
package is pending deprecation in favor ofimportlib
.
So, you should be using the reload
function from there:
>>> import importlib
>>> importlib.reload
<function reload at 0x01BA4030>
>>> importlib.reload(the_module)
