'module' object has no attribute 'choice' - trying to use random.choice
提问by AMHD
Could someone please tell me what I may be doing wrong. I keep getting this message when I run my python code:
有人可以告诉我我可能做错了什么。运行 python 代码时，我不断收到此消息：
import random
foo = ['a', 'b', 'c', 'd', 'e']
random_item = random.choice(foo)
print random_item
Error
错误
AttributeError: 'module' object has no attribute 'choice'
AttributeError: 'module' 对象没有属性 'choice'

Sounds like an import issue. Is there another module in the same directory named random? If so (and if you're on python2, which is obvious from print random_item) then it's importing that instead. Try not to shadow built-in names.
听起来像是导入问题。同一个目录中是否有另一个名为 的模块random？如果是这样（如果你在 python2 上，这很明显来自print random_item），那么它会导入它。尽量不要隐藏内置名称。
You can test this with the following code:
您可以使用以下代码对此进行测试：
import random
print random.__file__
The actual random.pymodule from stdlib lives in path/to/python/lib/random.py. If yours is somewhere else, this will tell you where it is.
random.pystdlib 中的实际模块位于path/to/python/lib/random.py. 如果你的在其他地方，这会告诉你它在哪里。

Shot in the dark: You probably named your script random.py. Do not name your script the same name as the module.
在黑暗中拍摄：您可能将脚本命名为random.py。不要将您的脚本命名为与模块相同的名称。
I say this because the randommodule indeed has a choicemethod, so the import is probably grabbing the wrong (read: undesired) module.
我这样说是因为random模块确实有一个choice方法，所以导入可能是抓取了错误的（阅读：不需要的）模块。

In short, Python's looking in the first file it finds named "random", and isn't finding the choice attribute.
简而言之，Python 正在查找它找到的第一个名为“random”的文件，并没有找到选择属性。
99.99% of the time, that means you've got a file in the path/directory that's already named "random". If that's true, rename it and try again. It should work.
99.99% 的情况下，这意味着您在路径/目录中有一个已命名为“随机”的文件。如果这是真的，请重命名并重试。它应该工作。

I also got this error by naming a method randomlike this:
我也通过命名这样的方法得到了这个错误random：
import random
def random():
foo = ['a', 'b', 'c', 'd', 'e']
random_item = random.choice(foo)
print random_item
random()
It's not your case (naming a file random.py) but for others that search about this error and may make this mistake.
这不是您的情况（命名文件random.py），而是其他搜索此错误并可能犯此错误的人。

for me the problem is I use
对我来说，问题是我使用
random.choices
in python 3.6 local dev but the server is python3.5 don't have this method...
在python 3.6本地开发但服务器是python3.5没有这个方法...
