Hi all.
In C, you can use pointers to reference variables, arrays, ETC. In python, I do not recall anything specifically that refers to such a capability. What I want to do is: I want to create different data structures such as dictionaries which contain specific list elements based upon specific keys. The original data structure could look like: Data = [ ['2019-01-19','Fred Flintstone',23], ['2019-02-01','Scooby doo', 99] ] The above structure does have 100's of elements. I want to reference specific lists within the above structure. Using the only method I know how: Category = {'under-50':[data[0]], 'over-50':[data[1]]} If I understand things correctly with Python. The above will copy the value into the list within the key. Not the memory address of the nested list I am referencing. I am using a list within the key to permit multiple references to different nested lists from the original data structure. The end result of the structure for the dict could look like this (using example, not real output) Category['under-50'] = [ List1 pointer, List22 pointer, List52 pointer] I hope the above makes sense. How can this be done? _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
