Distinction 1: Order Doesn't Matter to Python Dictionaries What this means is that, with dictionaries, the order of the pairs doesn’t matter. In fact, if you print a dictionary multiple times, you might get the pairs returned in a different order than you input them. ...
pop() >>> removed_item 'JavaScript' >>> languages ['Python'] Aside: Changing an object in Python is often called mutating. The append and pop methods both mutate the list.Indexing: looking up items by their positionLists are ordered, meaning they keep track of the relative positions of ...
a tuple of the class'sbase classes(which in this case is empty meaning this class has no base classes) a dictionary of the new class'sattributes and methods. We're giving this class one method (remember thatmethods are attributes that happens to be functions): ...
Here, an object of the socket class is created, and two parameters are passed to it. The first parameter, i.e., AF_INET, refers to the ipV4 address family, meaning only ipV4 addresses will be accepted by the socket. The second parameter, SOCK_STREAM, means connection-oriented TCP protoco...
It progresses through this range using 2 steps at a time, meaning it skips every other item: example_array[0:3:2] array('i', [2, 6]) Python’s slice notation is a powerful tool that can be used to perform many more complicated operations than demonstrated in this guide. To see ...
There are two types of reinforcement learning. Let’s have a look at them: 1. Positive Reinforcement Learning The agent is rewarded in Positive Reinforcement Learning for making the correct decisions. This motivates the agent to repeat the same action in the future. For eg, when an AI opponen...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
The “sum” and “len” methods used here are built into Python’s standard library, meaning you don’t need to import them. As you can see in the following example, implementing it works exactly like “mean” from “numpy”. defmean(numbers):returnsum(numbers)/len(numbers)x=mean([1,...
append(cls) class Plugin1(PluginBase): pass class Plugin2(PluginBase): pass In order to allow zero-argument super() calls to work correctly from __init_subclass__() implementations, custom metaclasses must ensure that the new __classcell__ namespace entry is propagated to type.__new__ ...
Features of Tkinter: Simple and Easy to Learn: Tkinter is designed to be simple and easy to learn, making it accessible for beginners in GUI programming with Python. Platform Independence: Tkinter is platform-independent, meaning that applications developed using Tkinter can run on different operatin...
