在 python (IDLE) 本身中,我知道如果我输入dir(list)
,我会得到一个 list 的属性列表,如下所示:
>>> dir(list)
['__add__', '__class__', '__contains__', '__delattr__', '__delitem__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort']
但是,我的问题是,如何在 .py 文件中执行此操作?如果我输入print(dir(list))
,我会在我的本地主机上收到以下错误
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.0/lib/python3.0/http/server.py", line 1031, in run_cgi
os.execve(scriptfile, args, os.environ)
OSError: [Errno 13] Permission denied
建议?
