I would like to get all duplicated keys from the dictionary. I know that dictionaries do not support duplicated keys, but maybe is it a workaround on it.
my_dict = {"key1":"value1", "key1":"value2", "key2":"value3", "key3":"value4", "key3":"value5", "key4": "value6"}
Desired output:
list_of_keys = ("key1", "key3")
I tried a lot of ideas which I found on Stackoverflow, but so far unsuccessfully.

From a traverser, if I just want the first item in the list of vertexes, how would I go about returning it as an object?
I've tried:
g.V()
.has("Project", "id", eq("someid"))
.outE("Contains")
.inV()
.hasLabel("Goal")
.sample(1)
.values("name")
Also tried:
g.V()
.has("Project", "id", eq("someid"))
.outE("Contains")
.inV()
.hasLabel("Goal")
.limit(1)
.values("name")
I've also tried fold but none of them worked for me. Any ideas?
I'm not quite following what you want but your either traversal should only return one "name" value and not a list of "name" values, though I think I'd prefer the second since you said you want the first item returned. I'd re-write it as follows though:
g.V().has("Project", "id", "someid").
out("Contains").hasLabel("Goal").
values("name")
limit(1)
You just pasted some Gremlin here, but you can also next() the Iterator to get that single first object:
String name = g.V().has("Project", "id", "someid").
...
limit(1).next()
If you're seeing some other behavior for some reason in the return values please update your question to include a sample data script (example) so that it's easy to reproduce in the Gremlin Console.
I have a list of identifiers as follows:
url_num <- c('85054655', '85023543', '85001177', '84988480', '84978776', '84952756', '84940316', '84916976', '84901819', '84884081', '84862066', '84848942', '84820189', '84814935', '84808144')
And from each of these I'm creating a unique variable:
for (id in url_num){
assign(paste('test_', id, sep = ""), FUNCTION GOES HERE)
}
This leaves me with my variables which are:
test_8505465, test_85023543, etc, etc
Each of them hold the correct output from the function (I've checked), however my next step is to combine them into one big vector which holds all of these created variables as a seperate element in the vector. This is easy enough via:
c(test_85054655,test_85023543,test_85001177,test_84988480,test_84978776,test_84952756,test_84940316,test_84916976,test_84901819,test_84884081,test_84862066,test_84848942,test_84820189,test_84814935,test_84808144)
However, as I update the original 'url_num' vector with new identifiers, I'd also have to come down to the above chunk and update this too!
Surely there's a more automated way I can setup the above chunk?
Maybe some sort of concat() function in the original for-loop which just adds each created variable straight into an empty vector right then and there?
So far I've just been trying to list all the variable names and somehow get the output to be in an acceptable format to get thrown straight into the c() function.
for (id in url_num){
cat(as.name(paste('test_', id, ",", sep = "")))
}
...which results in:
test_85054655,test_85023543,test_85001177,test_84988480,test_84978776,test_84952756,test_84940316,test_84916976,test_84901819,test_84884081,test_84862066,test_84848942,test_84820189,test_84814935,test_84808144,
This is close to the output I'm looking for but because it's using the cat() function it's essentially a print statement and its output can't really get put anywhere. Not to mention I feel like this method I've attempted is wrong to begin with and there must be something simpler I'm missing.
Thanks in advance for any help you guys can give me!

I think this won't be very complex, but I'm unable to figure this out.
I have in Matlab a 17x1 struct object with 6 fields, named photolist. I only want to export the name field , to use in R.
photolist.name gives me the list I need, but when I want to store it in a variable:
name = photolist.name
I only get the first value, same for
name = getfield(photo_list, 'name')
and while
name = [photolist.name]
gives me all values, it does so in one long string without spaces.
using
save('temp.mat', 'photolist')
gives me something I can import to R, but then I need to go multiple nested layers deep to get the values I need, which is a workaround but not very satisfying.
How do i save just the .name fields to a variable?
Found it, was already answered here
names = extractfield(photolist, 'name')
And another way to get the same result is:
names = {photolist.name}
I am trying to build a query to get the student results for a specific exam as a table that can be merge to a word document. The following works fine but seems very ineficient since I need to call the same query twice in the same iif statement.
Test1: IIf(Round((SELECT tblMarks.Score FROM tblMarks WHERE tblMarks.Test = 'Test1' AND [tblMarks].[ID] = [tblStudents].ID AND [tblMarks].[Rewrite] = false)*100,0)<70,70,Round((SELECT tblMarks.Score FROM tblMarks WHERE tblMarks.Test = 'Test1' AND [tblMarks].[ID] = [tblStudents].ID AND [tblMarks].[Rewrite] = false)*100,0))
To get rid of the second query call I tried the following but StudentScore is not being recognized by the IIF false condition.
Test1: IIf(Round((SELECT tblMarks.Score AS StudentScore FROM tblMarks WHERE tblMarks.Test = 'Test1' AND [tblMarks].[ID] = [tblStudents].ID AND [tblMarks].[Rewrite] = false)*100,0)<70,70, StudentScore)
I have many of those test field (test2, test3 etc...) so even just removing the extra query per field would probably help speed things up quite a bit.
Does anyone has any idea if what I am trying to do even possible??? Any help appreciated.
Thanks.
UPDATE:
I am trying to create a table/query to be use to merge into an MS Word document with fields. This new query combines many tables into one. Here's and example of the table structure:
tblStudent: StudentID, Name etc... A lot of personal info.
tblScore: StudentID, Test, Score, Rewrite etc...
New Query field are:
DISTINCT tblStudent.StudentID, tblStudent.Name, tblScore.Test(as shown above) AS Test1, tblScore.Test(Same as above but with test2) AS Test2, ... Where CourseName.....
Hope this help people see what I am trying to do; which work fine I am just trying to eliminate the second query in the if statement. Sorry this is the best I can do right now since I am not at work right now and this is where all this stuff is stored.
Is it possible to get a list of declared variables with a VimL (aka VimScript) expression? I'd like to get the same set of values that will be presented for a command using -complete=expression. The goal is to augment that list for use in a user-defined command completion function.
You can use g: as a dictionary that holds all global variables, so:
let globals = keys(g:)
will give you all the names. The same applies to the other scopes: b:, s:, w:, etc. See :help internal-variables for the complete list.
You can get something similar using keys of g:, b:, t:, w: and v: dictionaries, but beware of the following facts:
There is no equivalent to this dictionaries if you want to complete options.
Some variables like count (but not g:count or l:count), b:changedtick and, maybe, others are not present in this dictionaries.
Some vim hacker may add key ### to dictionary g:, but it won't make expression g:### valid variable name (but adding 000 there will). Though g:["###"] will be a valid expression.
