Calculating the quotient between two files and writing it into another file

由 萝らか妹 提交于 2019-12-11 07:15:24
问题 Using Python, I have two large (equally long) files in which the numbers are divided by spaces: 0.11158E-13 0.11195E-13 0.11233E-13 ... # file1 0.11010E-13 0.11070E-13 0.11117E-13 ... # file2 There are differences in the values and I would like to get the relative differences and writing them in the same format into a third file. I can do it for the first value but have problem when it comes to ITERATING the process (so that all values are computed). This is the code (I am new to the python

SQL SUM of values between two dates calculated fields

由 旧巷老猫 提交于 2019-12-11 04:14:49
问题 I have this query, which returns null: SELECT SUM(sales) as [MAT] from TABLE2 where Date1 between CONVERT(VARCHAR(23), DATEADD(MONTH, -11, Date1), 111) and CONVERT(VARCHAR(23), DATEADD(MONTH, 0, Date1), 111); In the columns, date1 is in the format YYYY-DD-MM , which is why I convert it. I want the sum of the amounts from each date by product (another field) between those two dates. --UPDATE-- Hi, i already changed the format to DATETIME . Now the query looks like this: SELECT SUM(sales)as

Linq expression for executing a “Between”

由 ♀尐吖头ヾ 提交于 2019-12-10 21:36:19
问题 In SQL you have the ability to write a query that executes a between on a column that is of type 'nvachar' and simply returns to you all the rows that are between the min and max values specified. For Example, Table (Id:Int, Name:nvarchar): Contents: 1, Annie 2, Bill 3, Frank 4, Phil 5, Ted Select * where Name Between 'Frank' and 'Ted' Should return Frank, Phil, and Ted. Is there a way to do this with linq or am I going to have to create a custom query and execute it? The only examples I have

Prolog: between/3 with a list at the end

由 牧云@^-^@ 提交于 2019-12-10 20:29:09
问题 my question comes up because of this question Can you write between/3 in pure prolog? would it be possible to make between/3 and the third argument is a list so if you ask between(2,6,X). it comes X=[2,3,4,5,6] and not like X=2 X=3 X=4 .... I can’t figure out how this must work (all my solutions don’t work..) I’m a Prolog beginner so I have no idea.. sorry for the bad English.. Thanks for your help :) 回答1: Start by going to the library and getting a good book, for example "The Art of Prolog"

Android SQLite “BETWEEN” not inclusive or returns all records

问题 Very simple task it would seem, trying to get a given range of records/rows in my SQLite db in Android app with the following : String[] projection = {"_id"}; String selection = "_id between ? and ?"; String[] selectionArgs = {"1", "10"}; queryBuilder.query(db, projection, selection, selectionArgs, null, null, null); With the above selectionArgs I'm getting just the two rows, row 1 and 10. If I change arg to anything else I'm getting the whole lot (entire set of records/rows) as if there was
