问题描述
还是新的。学习属性和功能等等。
对不起，如果这是显而易见的，但是如果我为某些
词典定义一个函数，我怎么能只打印字典的名称？
例如假设应用程序，目录，网站是模块中定义的词典，
如何在与其他人做其他事情之前打印他们的名字。
def printdict（ dicts = [app，dirs，sites]）：
dict in dicts：
打印???
谢谢

Still new. Learning attributes and functions and so on.
Sorry if this is obvious, but if I''m defining a function for some
dictionaries, how can I print just the names of the dictionaries?
E.g. assuming apps, dirs, sites are dictionaries defined in the module,
how can I print just their names before doing other things with them.
def printdict(dicts=[apps, dirs, sites]):
for dict in dicts:
print ???
Thank you

[''alpha''，''beta'']
当然，最简单的方法就是使用元组（字典，字符串）。
作为旁注，因为dict是内置类型，功能，它可能不是
将它用作循环变量的好方式。

[''alpha'', ''beta'']
Of course, the easiest way is just to use a tuple (dict,string).
As a side note, since dict is a builtin type and function, it might not
be good style to use it as a loop variable.
