问题 I found Greg Reda's blog post about scraping HTML from nba.com: http://www.gregreda.com/2015/02/15/web-scraping-finding-the-api/ I tried to work with the code he wrote there: import requests import json url = 'http://stats.nba.com/stats/leaguedashteamshotlocations?Conference=&DateFr' + \ 'om=&DateTo=&DistanceRange=By+Zone&Division=&GameScope=&GameSegment=&LastN' + \ 'Games=0&LeagueID=00&Location=&MeasureType=Opponent&Month=0&OpponentTeamID' + \ '=0&Outcome=&PORound=0&PaceAdjust=N&PerMode

问题 I have 1000 files each having one million lines. Each line has the following form: a number,a text I want to remove all of the numbers from the beginning of every line of every file. including the , Example: 14671823,aboasdyflj -> aboasdyflj What I'm doing is: os.system("sed -i -- 's/^.*,//g' data/*") and it works fine but it's taking a huge amount of time. What is the fastest way to do this? I'm coding in python. 回答1: This is much faster: cut -f2 -d ',' data.txt > tmp.txt && mv tmp.txt data

问题 I'm working with some text in python, it's already in unicode format internally but I would like to get rid of some special characters and replace them with more standard versions. I currently have a line that looks like this, but it's getting ever more complex and I see it will eventually bring more trouble. tmp = infile.lower().replace(u"\u2018", "'").replace(u"\u2019", "'").replace(u"\u2013", "").replace(u"\u2026", "") for example the u\2018 and \u2019 are left and right single quotes.

问题 Sometimes I want to see how many times a certain function is called in a file or a code block. How do you do that? I am using Vim 7.2. I presume you have to use !wc or some such. 回答1: For counting the number of times some pattern occurs, use: :%s/pattern//gn The 'n' flag count the number of occurrences without doing any change to the document. For counting the total number of words, you have several options. If you want to run as an external command: :!wc -w % If you want to run it inside VIM
