my_dict = {"1":1,"2":2}
print my_dict

Out[4]:
In [20]:
my_dict.update({"1":2})

In [21]:
new_dict = my_dict.copy()
print new_dict
You can use iterkeys method to get the iternerator of keys, and wrap a list function to get the list value.
In [22]:
print (list(new_dict.iterkeys()))
print (list(new_dict.itervalues()))
In [30]:
new_dict["3"] =3
print new_dict
