python dict.add_by_value(dict_2)?

由 六眼飞鱼酱① 提交于 2019-12-17 09:56:22
问题 The problem: >>> a = dict(a=1,b=2 ) >>> b = dict( b=3,c=2) >>> c = ??? c = {'a': 1, 'b': 5, 'c': 2} So, the idea is two add to dictionaries by int/float values in the shortest form. Here's one solution that I've devised, but I don't like it, cause it's long: c = dict([(i,a.get(i,0) + b.get(i,0)) for i in set(a.keys()+b.keys())]) I think there must be a shorter/concise solution (maybe something to do with reduce and operator module? itertools?)... Any ideas? Update: I'm really hoping to find

Some examples would be (powers of 2 for programming fun): 2 -> Two 1024 -> One Thousand Twenty Four 1048576 -> One Million Forty Eight Thousand Five Hundred Seventy Six The algorithm my co-worker

Codegolf: Convert csv to HTML table with smallest amount of code in C#

问题 I'm adding a function to my own personal toolkit lib to do simple CSV to HTML table conversion. I would like the smallest possible piece of code to do this in C# , and it needs to be able to handle CSV files in excess of ~500mb. So far my two contenders are splitting csv into arrays by delimiters and building HTML output search-replace delimiters with table th tr td tags Assume that the file/read/disk operations are already handled... i.e., i'm passing a string containing the contents of said

问题 Locked . This question and its answers are locked because the question is off-topic but has historical significance. It is not currently accepting new answers or interactions. (Thanks to greg0ire below for helping with key concepts) The challenge: Build a program that finds all substrings and "tags" them with color attributes (effectively highlighting them in XML). The rules: This should only be done for substrings of length 2 or more. Substrings are just strings of consecutive characters,
