问题描述
我正在尝试学习python而我正在尝试编写一些简单的东西。我正在使用OS X 10.8在Pydev（Eclipse）下开发。我使用64位.dmg安装程序安装了python 3.2。
I'm trying to learn python and I was trying to write something simple. I am developing under Pydev (Eclipse) using OS X 10.8. I installed python 3.2 using the 64bits .dmg installer.
我成功配置了Python解释器（或者我认为是这样，因为我实际上可以创建一个hello world项目和运行）。但由于某种原因，当我尝试导入Set（ from sets import Set ）时，我收到此错误：
I configured the Python interpreter successfully (or I think so, as I actually can create a "hello world" project and run it). But for some reason, when I try to import Set (from sets import Set) I get this error:
from sets import Set;
ImportError: No module named sets
我也在命令行测试了它，并给出了我同样的错误。
I have tested it on command line too, and gives me the same error.
然后我查看了我的python3目录中的lib文件夹（在 /Library/Frameworks/Python.framework/Versions下） /3.2/lib/python3.2 / ）并且它缺少sets.py文件！最初的2.7版本确实有 /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /
Then I have looked at the lib folder from my python3 directory (under /Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/) and it's missing sets.py file!!! The original 2.7 version does have it at /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/
我也尝试将2.7 sets.py复制到3.2，但它既不起作用......
请知道我该怎么办？
I have also tried to copy the 2.7 sets.py to the 3.2, but it neither works...Please, do you know what have I to do?
推荐答案
您不再需要 sets 模块。 是Python 3中的内置类，无需导入即可使用。
You don't need the sets module anymore. set is a built-in class in Python 3 and can be used without import.
mySet = set()
