09/02/2018В В· List vs tuple vs dictionary in Python. Dictionary is unordered collection. List and dictionary objects are mutable i.e. it is possible to add new item or delete and item from it. Tuple is an immutable object. Addition or deletion operations are not possible on tuple object. Dictionary vs. List Loops. Dictionary optimizes lookup of keys. The List provides an easily-resized array type. But the Dictionary is not faster in all situations. One case where List is faster is when looping over all elements.Optimization. Tip: If looping through elements is a common task in a program, a List is more efficient.

So, if you want to lookup a value using a key dictionary is better for performance over list. So, use dictionary when you know the collection will be primarily used for lookups.

There is no truth to be found in the above statement. Using generics has a *huge* performance impact when dealing with value types. In the case of the arraylist or hashtable it will store boxed value types where as in the generic examples it will not store boxed versions the overhead of the boxing and unboxing and the extra lookup they Out of curiosity after reading some articles on how the HashSet (introduced in .Net 3.5) class is more performant than the List class for set operations, I set about doing some experiments of my own to get a feel of just how much faster a HashSet is, and under what circumstances.
