python-unicode

问题 I have a foreign C library which uses utf-16 in API: as function arguments, return values and structure members. On Windows its OK with ctypes.c_wchar_p, but under OSX ctypes uses UCS-32 in c_wchar and I could not find the way to support utf-16. Here is my research: Use _SimpleCData subclassing to redefine _check_retval_. it allows a transparent conversion of utf-16 to Python string. can be placed as C structure member But it doesn't allow to handle strings as arguments, its from_param()

问题 I've been trying to write a script that would potentially scrape the list of usernames off the comments section on a defined YouTube video and paste those usernames onto a .csv file. Here's the script : from selenium import webdriver import time import csv from selenium.webdriver.common.keys import Keys from bs4 import BeautifulSoup as soup driver=webdriver.Chrome() driver.get('https://www.youtube.com/watch?v=VIDEOURL') time.sleep(5) driver.execute_script("window.scrollTo(0, 500)") time.sleep

问题 I have a pandas DataFrame containing a column with Wikipedia urls, that I want to load. However, some strings won't load because they contain unicodes. For example, 'Kruskal %E2%80%93 Wallis_one-way_analysis_of_variance' raises the following PageError: Page id "Cauchy%E2%80%93Schwarz_inequality" does not match any pages. Try another id! Is there a way to turn all unicodes into ascii? So in this case, I need a function that can create a new column: old column new column Cauchy%E2%80%93Schwarz

问题 I am crawling several websites and extract the names of the products.

问题 I am printing a formatted table. But sometimes these user generated characters are taking more than one character width and it messes up the formatting as you can see in the screenshot below... The width of the "title" column is formatted to be 68 bytes. But these "special characters" are taking up more than 1 character width but are only counted as 1 character. This pushes the column past its bounds. print('{0:16s}{3:<18s}{1:68s}{2:>8n}'.format(( ' ' + streamer['user_name'][:12] + '..') if
