loops

问题 I'm new at sqlplus and I need a help. I have the select below, and I want to add a While looping to generate a CSV file for each day of the period. Can someone help me? Thanks! set pagesize 0 set colsep '|' set echo off set feedback off set linesize 1000 set trimspool on set headsep off define start_date = '01/01/2004' define end_date = '02/01/2004' define start_csv = TO_CHAR(TO_DATE('&start_date.','DD/MM/YYYY'), 'YYYY-MM-DD') define end_csv = TO_CHAR(TO_DATE('&start_date.','DD/MM/YYYY'),

问题 I am implementing an emotion analysis using lstm method, I have already trained my model and I am doing my prediction part where I have already done the prediction correctly. Now i want to add the output I obtained in a dataframe, I tried it but I am having wrong results. Can someone please help me with the correction of my codes please. I am posting my codes along with the output obtained and how I want my output to be. Here are my codes: with open('output1.json', 'w') as f: json.dump(new

问题 I recently came across this code: for (const temp of [1,2]) { // do something } I thought that it'd be better to use let declaration for temp because this way the variable would be declared only once. However, I also ran this example as well as the version with let through babel and this is what I see: for (const p of [1,2]) { } for (let s of [1,2]) { } became: for (var _i = 0, _arr = [1, 2]; _i < _arr.length; _i++) { var p = _arr[_i]; } for (var _i2 = 0, _arr2 = [1, 2]; _i2 < _arr2.length;

问题 I have seen a lot of similar questions, but there is one key to the loop that I am trying to write that I am missing. I have a a set of dataset with ~4,000 different keys, and for each key, there are ~1,000 observations. I have filtered out a key to isolate the observations for that key, run linear regression, checked model assumptions and all looks good. However, I want to loop over this dataset and run that linear regression for each of the keys. Then I will want to store the coefficients,

问题 I would like to add (numerous) conditions to a loop that cycles through my data (and currently only picks the closest (not necessarily most recent) previous owner within a set distance). Previous owners (>20,000) are stored in a dataset called lifetime_census (data available here): previous_id reflo locx locy lifespan census_year gr 5587 -310 -3 10 1810 2003 A 7687 -310 -3 10.1 110 2001 A 5101 Q1 17.3 0.8 55 2004 A 9109 Q1 17.4 0.9 953 2003 B 6077 M2 13 1.8 979 2003 B 8044 M2 13.1 1.7 100

问题 How can I convert my Excel VBA code, which currently loops by row, to loop through sets of 20 rows? I understand that the Step function might work together with the following line .Range("V1").Value = Application.Index(vInput1, r, 0) . However, I am unsure of how to amend my code to loop through each batch of 20 rows and shift down by 20 rows to loop through the next set of 20 rows. Note: after 'pasting' each set of 20 rows into .range(V1) , Excel calculations are used to generate the output

问题 How to get the loop values outside the loop below example only prints the last value, For example if i wanted to print the loop results. var result; for (var i=0; i < 10; i++) { result = i; } console.log(result); Now how can i get the iterated values of the loop which are (1 to 10) in the console, because now i will only print the last value which is 10. 回答1: Put the log statement inside the loop where you set the value. var result; for (var i=0; i < 10; i++) { result = i; console.log(result)
