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 WTF
Another common approach to mimicking pointers in Python is to use a dict. Let’s say you had an application where you wanted to keep track of every time an interesting event happened. One way to achieve this would be to create a dict and use one of the items as a counter: Python >...
To find the total number of hotspots in New York as well as the company that provides most of them, you create the following script: Python # hotspots.py import csv from collections import Counter def process_hotspots(file): def most_common_provider(file_obj): hotspots = [] with file_...
Textbox in the 'flet' library for Python is represented by 'ft.TextField' and is used to create a graphical user interface (GUI) text input field, allowing users to enter text data into a form. Flet provides a number of controls for building forms: TextField, Checkbox, Dropdown, Elevate...
We also found that developers have experience of encountering a diverse set of problematic code snippets online, that copying code from websites without checking its quality or understanding how it worked is common, and that using online resources in this way had a potentially counter-productive eff...
Iterators: An iterator is any Python object that implements the __iter__() and __next__() methods. You can create custom iterator classes to iterate over objects in a specific way. Collections: Python’s collections module provides specialized container datatypes. Some of these, like Counter,...
在内置数据类型(dict、list、set、tuple)的基础上,collections模块还提供了几个额外的数据类型:Counter、deque、defaultdict、namedtuple和OrderedDict等。 1.namedtuple: 生成可以使用名字来访问元素内容的tuple 2.deque: 双端队列,可以快速的从另外一侧追加和推出对象 ...
"explicit is better than implicit" i'd counter with "practicality beats purity" and "flat is better than nested", not to mention a foolish consistency is the hobgoblin of little minds . level 2 1 point · 6 years ago "there's nothing hacky about this at all" damn r...
It might get some data, and it might store data back into memory. And after it's done, the ALU is going to go back, and the program counter is going to increase by 1, which means that we're going to go to the next sequence in the instruction set. And it just goes linearly inst...
What is a thread? A thread can be defined as an ordered stream of instructions that can be scheduled to run as such by operating systems. These threads, typically, live within processes, and consist of a program counter, a stack, and a set of registers as well as an identifier. These ...
