First of all I am new to Python. I am using PTVS http://pytools.codeplex.com/. Next I installed reportlab. Then I run a sample demo at https://github.com/nakagami/reportlab/blob/master/demos/colors/colortest.py#L68But at line,
首先，我是 Python 的新手。我正在使用 PTVS http://pytools.codeplex.com/。接下来我安装了reportlab。然后我在https://github.com/nakagami/reportlab/blob/master/demos/colors/colortest.py#L68 上运行一个示例演示但是在线，
all_colors = reportlab.lib.colors.getAllNamedColors().items()
all_colors.sort() # alpha order by name
I am getting error, dict_items object has no attribute sort
我收到错误， dict_items object has no attribute sort

Haven't tested but a theory: you are using python3!

dict methods dict.keys(), dict.items() and dict.values() return “views” instead of lists. For example, this no longer works: k = d.keys(); k.sort(). Use k = sorted(d) instead (this works in Python 2.5 too and is just as efficient).
dict 方法 dict.keys()、dict.items() 和 dict.values() 返回“视图”而不是列表。例如，这不再有效： k = d.keys(); k.sort()。改用 k = sorted(d) （这也适用于 Python 2.5 并且同样有效）。
as I understand it a "view" is an iterator, and an iterator does not have the sort function. Change it to
据我了解，“视图”是一个迭代器，而迭代器没有排序功能。将其更改为
sorted(all_colors)
according to the documentation
根据文档

So the total solution based on Johan's answer is:
因此，基于 Johan 的答案的总解决方案是：
all_colors = sorted(reportlab.lib.colors.getAllNamedColors().items())

I believe the sort()method doesn't support Python 3.xanymore.
我相信sort()法不支持Python 3.x都有了。
It is necessary to pass the corresponding variable to the sorted(all_colors).
需要将相应的变量传递给sorted(all_colors).
