concatenation

问题 I'm trying to get a column to automatically fill up with incrementing strings depending on the row number in an ARRAYFORMULA in Google sheets. I can easily get a column to show a shifted row number by putting =ARRAYFORMULA(ROW(A:A)-1) in the top cell. However trying to use this ROW call inside CONCATENATE does not give me the result I want, I've tried with and without TO_TEXT . In the image the formula used for the different columns are: A1: =ARRAYFORMULA(ROW(A:A)-1) B1: =ARRAYFORMULA(IF(ROW

问题 i have a field for date with date, month and year.In my visualization, I need date to be displayed in (MON-Year) format. I switched to data view, created calculated column with Mon-Year = FORMAT('table'[Date],"YYYY-MM") Now it's getting displayed as (YEAR and Month number) but I want to change it as month name. After changes in data view, when I close apply, the column is present but there is no data type visible. Should I create different calculated fields for year and month separately and

问题 I'm looking to combine several columns into one, I do not care about order. For example, I have a column with a collection of tags: | || A | | = || ====================== | | 1 || Tags List | | 2 || Loon, Diver, Gaviform | | 3 || Shoveler, Anseriformes | | 4 || Roc | If I use the formula =ARRAYFORMULA(SPLIT(A2:A)) in B2 , I would get the following output: | || B | C | D | | = || ======== | ============ | ========= | | 1 || | | | | 2 || Loon | Diver | Gaviform | | 3 || Shoveler | Anseriformes

问题 I am using C# to concatenate two strings with escapes sequences, that i want to skip so I'm using @ symbol before each string. It looks like this: string firstString = @"Use \n for line break. "; string secondString = @"Use \b for backspace"; return firstString + secondString; The question is: Will that escapes sequences be skipped in the returned value?; 回答1: Other answers are of course correct. For making it clear; This is covered in section 2.4.4.5 of the C# specification: 2.4.4.5 String

问题 I would like to loop through several pages of data which I am accessing through an API, and concatenate the pages to the same dictionary as the loop progresses. So far I managed to loop through all the pages and could print out as the loop goes on, so when the loop is over, all the pages are printed out. But my dictionary contains only the last page! page = 5 i = 0 for i in range(0, page): url =f'http://hotell.difi.no/api/json/npd/wellbore/withcoordinates?page={i+1}' dataset_all = requests

问题 I have large csv files with size more than 10 mb each and about 50+ such files. These inputs have more than 25 columns and more than 50K rows. All these have same headers and I am trying to merge them into one csv with headers to be mentioned only one time. Option: One Code: Working for small sized csv -- 25+ columns but size of the file in kbs. import pandas as pd import glob interesting_files = glob.glob("*.csv") df_list = [] for filename in sorted(interesting_files): df_list.append(pd.read

问题 I need an Excel macro to join seven columns of data on each row until the end of the data is reached. For example if I have a formula like this: =A1&B1&C1&D1&E1&F1&G1 How can I write the macro so that it increments for every row to the end of the file in a sequence like this? =A1&B1&C1&D1&E1&F1&G1 =A2&B2&C2&D2&E2&F2&G2 =A3&B3&C3&D3&E3&F3&G3 回答1: With so many answers, the main focus on what assylias and I were highlighting has gone to waste :) However, if you still want a VBA answer.

问题 I have a .csv file with demographic data for my participants. The data are coded and downloaded from my study database (REDCap) in a way that each race has its own separate column. That is, each participant has a value in each of these columns (1 if endorsed, 0 if unendorsed). It looks something like this: SubjID Sex Age White AA Asian Other 001 F 62 0 1 0 0 002 M 66 1 0 0 0 I have to use a roundabout way to get my demographic summary stats. There's gotta be a simpler way to do this. My

问题 Javascript lacks a class construct, however you can still achieve inheritance many different ways. You can mimic classes by utilizing prototypes to create constructor functions and thus implementing inheritance via delegation. The most common way to do this is with the new keyword, but you can also implement object.create() . Alternatively, you can take a concatenative approach and copy behavior that you want your object to inherit directly into the object itself, rather than by pointing its
