Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is required that objects that compare equal also have the same ...
As you can see in the example above, the mean methoddoes notbelong to the Python standard library. To use this method, you need to import it from an external module, like “NumPy” or “statistics”. You may need to install these modules, but once that’s done, you can easily integra...
