Dictionaries are a great way to show a key-value relationship. In this case, the key can be an action, like scissors, and the value can be a list of actions that it beats. So what would this look like for your determine_winner() with only three options? Well, each Action can beat...
With that in mind, this article presents a “top 10” list of somewhat subtle, harder-to-catch mistakes that can bite even some more advanced Python developers in the rear.(Note: This article is intended for a more advanced audience than Common Mistakes of Python Programmers, w...
We might conjoin lst and dct to represent a list of dictionaries: lctResults When we instantiate a class, we have an object, so obj seems legit: objMyReallyLongName But that’s an awfully long name, so as long as we’re throwing out unneeded characters, why not boost our job security...

The full list of ways to create arrays in NumPy is listed in the official documentation. The one big difference between MATLAB and NumPy in terms of array creation routines is that MATLAB supports simply using the colon to create an array, while NumPy does not. Instead, NumPy uses arange()...
Each data structure has a significant effect on runtime. There are many built-in data structures such as list, tuple, set, and dictionary in python. Most people use a list data structure in all cases. In python, sets and dictionaries have O(1) lookup performance as they use hash tables...

Using another for statement, this function will run through the dictionary object, checking each key against our list of items sold. It then finds the price of that item using the integrated Python dictionary method .get(), which returns the value (the selling price of an item) of each ...
