First, importing a package doesn't automatically import all of its submodules.*
首先，导入包不会自动导入其所有子模块。*
So try this:
所以试试这个：
import http.client
If that doesn't work, then most likely you've got a file named http.py, or a directory named http, somewhere else on your sys.path(most likely the current directory). You can check that pretty easily:
如果这不起作用，那么很可能您有一个名为 的文件http.py，或名为 的目录http，位于您的其他位置sys.path（很可能是当前目录）。你可以很容易地检查：
import http
http.__file__
That should give some directory like /usr/lib/python3.3/http/__init__.pyor /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/__init__.pyor something else that looks obviously system-y and stdlib-y; if you instead get /home/me/src/myproject/http.py, this is your problem. Fix it by renaming your module so it doesn't have the same name as a stdlib module you want to use.
那应该给出一些类似/usr/lib/python3.3/http/__init__.py或/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/__init__.py其他看起来很明显 system-y 和 stdlib-y 的目录；如果您改为 get /home/me/src/myproject/http.py，这是您的问题。通过重命名您的模块来修复它，使其与您要使用的 stdlib 模块不具有相同的名称。
If that's not the problem, then you may have a broken Python installation, or two Python installations that are confusing each other. The most common cause of this is that installing your second Python edited your PYTHONPATHenvironment variable, but your first Python is still the one that gets run when you just type python.
如果这不是问题，那么您可能有一个损坏的 Python 安装，或者两个相互混淆的 Python 安装。最常见的原因是安装你的第二个 Python 编辑了你的PYTHONPATH环境变量，但你的第一个 Python 仍然是当你输入python.
* But sometimes it does. It depends on the module. And sometimes you can't tell whether something is a package with non-module members (like http), or a module with submodules (os). Fortunately, it doesn't matter; it's always save to import os.pathor import http.client, whether it's necessary or not.
* 但有时确实如此。这取决于模块。有时您无法判断某个东西是具有非模块成员（如http）的包，还是具有子模块（os）的模块。幸运的是，这并不重要；无论是否有必要，它总是保存到import os.pathor import http.client。
