separator

问题 I would like to subset a file while I keep the separator in the subsetted output using ´awk´ in bash. That´s what I am using: The input file is created in R language with: inp <- 'AX-1 1 125 AA 0.2 1 AB -0.89 0 AA 0.005 0.56 AX-2 2 456 AA 0 0 AA -0.56 0.56 AB -0.003 0 AX-3 3 3445 BB 1.2 1 NA 0.002 0 AA 0.005 0.55' inp <- read.table(text=inp, header=F) write.table(inp, "inp.txt", col.names=F, row.names=F, quote=F, sep="\t") (So fields are separated by tabs) The code in bash: awk {'print $1 $2

问题 I am retrieving information from a REST API and it displays: "Per 78g - Calories: 221kcal | Fat: 12.65g | Carbs: 16.20g | Protein: 10.88g" I have imported the items into a ListView and when a user clicks an item I would like to string each numeric value individually like below without their text. Based on the example above: String calories = 221; String fat = 12.65; String carbs = 16.20; String protein = 10.88; I got rid of the "Per 78g" with: String sd = food.getString("food_description");

问题 A question regarding a parser. Is there any chance to catch some separators within the that separate the table... The paser script runs allready nicely. Note - i want to store the data into a MySQL database. So it would be great to have some seperators - (commas, tabs or somewhat else - a tab seperated values or comma seperated values are handy formats to work with...

问题 Why would I choose to use . DIRECTORY_SEPARATOR . instead of . "/" . ? My initial thought was that there could be a different separator instead of a slash, but if I'm designing, say, a Wordpress Plugin, can I not assume that there is always a / separating two folders? 回答1: If the application is going to run on a variety of operating systems then the directory won't always be a forward slash. It's a backwards slash on Windows for example. A similar case is new lines. It's \n on *nix, \r\n on

问题 So typically if I wanted to insert locale appropriate separators in some number, foo , I'd do something like this: ostringstream out; out.imbue(locale("en-US")); out << foo; Then I could just use out.str() as the separated string: http://coliru.stacked-crooked.com/a/054e927de25b5ad0 Unfortunately I've been asked not to use stringstreams in my current project. Is there any other way I can accomplish this? Ideally a locale dependent way? 回答1: So this answer is the C++ distillation of Jerry

问题 Using JavaScript, Is there a way to split the string to an array with two separators: ':' and ',' For var str = "21:223, 310:320"; would like the Result to be: [21, 223, 310, 320]; Thanks! 回答1: You could use a regular expression which looks for a : or for a comma with an optional space , . console.log("21:223, 310:320,42".split(/:|, */)); 回答2: You can use match if your expression is like this "21:223, 310:320" var str = "21 : 223 , 310 : 320 "; //---------^^----^^^---^^^----^^^-- // group of

问题 I have list: print (L) [('I', 'WW'), ('am', 'XX'), ('newbie', 'YY'), ('.', 'ZZ'), ('You', 'WW'), ('are', 'XX'), ('cool', 'YY'), ('.', 'ZZ')] I want split list to sublists with separator ('.', 'ZZ') : print (new_L) [[('I', 'WW'), ('am', 'XX'), ('newbie', 'YY'), ('.', 'ZZ')], [('You', 'WW'), ('are', 'XX'), ('cool', 'YY'), ('.', 'ZZ')]] I am interested about another possible solutions, performance is important. 回答1: The for-loop approach will be faster, this requires only one-pass: >>> def juan

问题 I am trying to create a DataFrame by reading a csv file separated by '#####' 5 hashes The code is: import dask.dataframe as dd df = dd.read_csv('D:\temp.csv',sep='#####',engine='python') res = df.compute() Error is: dask.async.ValueError: Dask dataframe inspected the first 1,000 rows of your csv file to guess the data types of your columns. These first 1,000 rows led us to an incorrect guess. For example a column may have had integers in the first 1000 rows followed by a float or missing

问题 I have ugly string: oldstr = "0.100% fDrg: 2%,dgdv: 29% fGd dg 0.2%, Ghh-sf 2.2 dbgh: NONE dfgdf6 gd 3 " I need to insert char | after the last digit of number for next splitting by this inserted | . There is also value none , where is also added this separator: 0.100| fdrg: 2|,dgdv: 29| fgd dg 0.2|, ghh-sf 2.2|dbgh: none| dfgdf6|gd 3| I try this, but no success: print re.sub(r'(\d+[a-z %^.])', r'\1|', oldstr.lower()) 0.|100%| fdrg: 2%|,dgdv: 29%| fgd dg 0.|2%|, ghh-sf 2.|2 |dbgh: none dfgdf6
