Hi all,
hope you can help me understanding why the following happens:
In [213]: g = {'a': ['a1','a2'], 'b':['b1','b2']}
In [214]: rg = dict.fromkeys(g.keys(),[])
If you rewrite this as
bl = []
rg = dict.fromkeys(g.keys(),bl)
is the answer any more obvious?
It isn't since I erroneously assumed that a clone of the object would be
made in both cases.
Thanks for your help
