问题 Let's say I have this Kanji "亜" which is represented in JIS X 208 code in hex form: 0x3021. I want my Python program to convert that code into its UTF-8 form E4BA9C so that I can pass that string (URL-encoded) into my url like this http://jisho.org/api/v1/search/words?keyword=%E4%BA%9C I'm using Python 2.7.12 but I'm open to Python 3 solution as well 回答1: These are accessed under ISO 2022 codec. >>> '亜'.encode('iso2022_jp') b'\x1b$B0!\x1b(B' If I saw those bytes not framed by the escape

Improve this question What is a branchless way to do the following mapping? true -> +1 false -> -1 An easy way would be if b then 1 else -1 but I'm looking for a method to avoid the branch, i.e. if. If it is relevant, I'm using Python. 回答1: You can exploit the fact that in Python, the type bool is

问题 I am using AstroPy SkyCoord to do conversion from equatorial coordinates to galactic coordinates with millions data, it is extremely slow. Anyone has idea to speed it up, otherwise it takes forever to run the whole dataset. The code is below: from astropy import units as u from astropy.coordinates import SkyCoord import numpy as np ra1 = np.loadtxt('data.txt',usecols=(0,)) dec1 = np.loadtxt('data.txt',usecols=(1,)) size = len(ra1) for i in range(size): ra = ra1[i] dec = dec1[i] c = SkyCoord

问题 I am creating a bot that will record the Microsoft team live sessions. Audio recording is working fine but facing problems in generating the video file. The process I am following is that I am converting the video data into a byte array and then writing the data to a video format file. I am adding some code snippets, I have examined so far. 1. Stream videoStream = new FileStream(videoFilePath, FileMode.Create); BinaryWriter videoStreamWriter = new BinaryWriter(videoStream); videoStreamWriter
