It seems to me that this should be an easy thing to do with key
but I'm struggling.
I have two XML files with elements with
elements within.
They both have a @corresp
attribute and a @sameAs
attribute, but one of the files has is missing a number of the @sameAs
attributes.
I would like to copy over the missing @sameAs
attributes from one file to the other with the assumption that the @sameAs
value is paired with the @corresp
attribute's value (they are English/Spanish translations).
Where a value for @sameAs
already exists, I this should not be overwritten.
The @sameAs
- @corresp
pairs are valid across both m
and w
.
The input file looks like this:

QUESTION
I'm working in an Angular 11 Project.
I know there's the ngIf directive, which will only show the html element if set to true, but doesn't preserve spacing.
In the old AngularJS, there was ng-show and ng-hide. These properties would show/hide an element, but keep its spacing (effectively setting the css to visibility to hidden). But Angular no longer has those properties. Instead they recommend binding to the hidden property (https://angular.io/guide/ajs-quick-reference#ng-show).
However, this doesn't preserve the spacing (which is strange IMO).
Does Angular have a directive that hides the element while also preserving its spacing?
I can add a conditional class, where the class has a visibility of hidden, but I trying to confirm if Angular has a directive/property for this.
I wiped up a demo here: https://stackblitz.com/edit/hide-element-angular?file=src/app/autocomplete-auto-active-first-option-example.html
This shows the hidden and ngIf do not perserve spacing, while the conditional class will.

Answered 2021-May-12 at 11:09It seems on_press_key()
works only with single key like q
but not with combination alt+q
. Or maybe it is problem only on some systems. At least it doesn't work on my Linux.
Or maybe they change code in module. Answer in Checking for keyboard inputs uses too much cpu usage, Is there something wrong with my code? is 2 years old.
You can use add_hotkey()
and it doesn't need wait()
QUESTION
Trying to understand Gram-Schmidt process from this explanation:
http://mlwiki.org/index.php/Gram-Schmidt_Process
The steps of the calculation make sense to me. However the Python implementation included in the same article doesn't seem to be aligned.
...ANSWER
Answered 2021-May-26 at 01:36This is what the code does exactly
Basically it normalize the previous vector (column in A) and project the current one to it and to be subtracted by the current one.
Normalization happens with every vector for neat calculation.
The V2 equation above doesn't normalize the previous vector hence the difference.

QUESTION
I have a conditional formatting from VBA code for a column which applies when there is a change of value.
The column is actually a Price column, So when the price value is entered,based on some formulas i apply my condition. It is working when the decimal separator is "." (DOT) (For Example: 1.323)
But when the decimal separator is "," in the system setting. I'm getting error when adding formula for conditional formatting ..
**
- Code below..
**
...ANSWER
Answered 2021-May-19 at 11:09I assume it's not about the decimal separator but about the list separator. This separator is, among others, used as separator for function parameters.
Regular (cell-) formulas are always translated into the US versions. If you work on a system with list separator = ";" and enter a formula like =OR(A1=1;B1=2)
in a cell, in VBA you will see =OR(A1=1,B1=2)
. So far so good, all well known.
For some strange reasons, however, for formulas that are used in conditional formatting, the translation is not done, so you need to write the formula with the actual list separator character. You can get the current setting (it's not an Excel setting, it's a system setting) with Application.International(xlListSeparator)
. However, once set, the formula will work when you open that workbook on a system with different settings (so some kind of translation happens).
If you want to be flexible, do something like this:
QUESTION
I have a script task that builds an Excel file. The business needs certain columns formatted in certain ways. The code is below, and I am curious if there is a way to use the existing process to format the columns, or if once it is created and loaded, to then format the columns?
Update: What I decided to do is let the OLE process do it's thing and create the file, then write some Interop code to format the file, but it seems that the OLE process is locking the file, possibly with Excel just remaining open in the background. I cannot find any different way to make sure the OLE connection is completely closed. I also tried putting the Interop part in a different task but I got some kind of version error when trying to open the file.
Error: System.Runtime.InteropServices.COMException (0x800A03EC): Cannot access 'TA_Enrollment__106648_20210518.xlsx'. at Microsoft.Office.Interop.Excel._Workbook.SaveAs(Object Filename, Object FileFormat, Object Password, Object WriteResPassword, Object ReadOnlyRecommended, Object CreateBackup, XlSaveAsAccessMode AccessMode, Object ConflictResolution, Object AddToMru, Object TextCodepage, Object TextVisualLayout, Object Local)
Any assistance would be greatly appreciated.
...ANSWER
Answered 2021-May-05 at 01:12Based on the C# code you provided, the Script Task is using the System.Data.Oledb
namespace classes (OledbCommand, OledbConnection) to connect to the Excel files. OLE DB handles Excel files as a relational database. As an example, it forces a data type for each column while Excel allows multiple data types in each column.
Maybe using System.Data.Oledb namespace classes are the easiest way to read data from Excel, but it has many limitations and it is only used to perform CRUD operations. To change the formatting of the cells, you should use Microsoft.Office.Interop.Excel
or a Third-party library.
QUESTION
I'm trying to calculate the historical number of hits a player has gotten in day vs night games. For example given a player with 5 games, sorted from oldest games to most recent game the dn_hits column (daynight) for the first row would be zeros because this is the first game. The dn_hits for the second row would look at if the second game was a day game or a night game and then perform a backward-looking cumsum() on the hits column - summing all hits that happened on a day or night as the case may be. This would happen for each row in the group.
I have a sample data frame and sample output below. I've also included some psuedo code of what I believe I need to do to make the calculation
You can see in the output below:
Row 1: the dn_hits column for the first row for player AJ is 0 (no prior games or hits to cumsum);
Row 2: the second row for player AJ is 2 (AJ's second game was a day game and so was his first game. Therefore, we conditionally cumsum the first game hits = 2 where dn = "day");
Row 3: the third row for player AJ is 0 (game three is a night game, prior to game 3 player AJ only played in (2) day games so the conditional cumsum of hits from where dn = "night" is 0)
Can this be accomplished with dplyr or is this a job for purrr.

The script below takes one string input as a polyline and returns a data frame with the corresponding latitude/longitude pairs.
I would like to input to be a data set as follows:
ActivityID Polyline 1 PolyLineValue1 2 PolyLineValue2 3 PolyLineValue2and the output to be (keeping the ActivityID)
ActivityID latitude longitude 1 123 123 1 123 123 1 123 123 2 123 123 2 123 123 2 123 123 3 123 123 3 123 123 3 123 123I was thinking along the lines of iterating over the input dataset to do this but I've read here that's not a great idea performance wise.
Please can someone advice how to do this in Python?
