'module' object has no attribute '_version_'
提问by neanderslob
I'm screwing around with python and its pandas library but I keep running into a problem. While copying through a tutorial, I try to get the version number for a couple libraries, but when I do so, I get the following: AttributeError: 'module' object has no attribute '_version_'.
我正在使用 python 和它的 Pandas 库，但我一直遇到问题。虽然通过复制一个教程中，我试图让一对夫妇库的版本号，但是当我这样做，我得到如下：AttributeError: 'module' object has no attribute '_version_'。
Everything else works just fine, but it really doesn't like '_version_'for some reason. Anything I might be leaving out?
其他一切都很好，但'_version_'由于某种原因它真的不喜欢。我可能会遗漏什么？
See below for the exact code.
请参阅下面的确切代码。
import datetime
import pandas as pd
import pandas.io.data
from pandas import *
pd._version_
AttributeError: 'module' object has no attribute '_version_'

Use double underscores..
使用双下划线..
In [10]: pandas.__version__
Out[10]: '0.13.1'
Which is just a shorthand for pandas.version.version
这只是一个简写 pandas.version.version
PEP8suggests using __version__as the global variable to store a version number. Most libraries follow this and then offer a more readable variable or possibly a function which outputs the version in a usable form (like Django for example).
PEP8建议使用__version__作为全局变量来存储版本号。大多数库都遵循这一点，然后提供一个更具可读性的变量，或者可能是一个以可用形式输出版本的函数（例如 Django）。
