having some pains with the following code in Python:

dict_items = sample_dict.items()
sample_dict.clear()

where sample_dict is a dictionary from int to dict.

I am trying to save memory by clearing my dictionary (after this code is run I never use this dictionary to access values, I just care about the k,v pairs stored in the dict), but after dict.clear() is run, dict_items gets nuked. Running print(dict_items) yields the following:

[key1:{},key2:{}...]

Not very familiar with how memory is stored in python - how can I keep dict_items intact after running sample_dict.clear()?

CodePudding user response：

dict_item = [*sample_dict.items()]

CodePudding user response：

Just use the copy of the dictionary :

dict_items = sample_dict.copy().items()
sample_dict.clear()
