I would like to request the last 30 days of CrewHu Import data from today's date in this query. At the moment it is just set to get everything greater than the 25th September 2022 but I want to change this to be a dynamic value. Has anyone else had this problem / knows of a workaround?
let
Source = Json.Document(Web.Contents("https://api.crewhu.com/api" & "/v1/survey?query={""_updated_at"":{""$gte"":""2022-09-25T00:00:00.000Z""}}", [Headers=[X_CREWHU_APITOKEN="xxxxxxxxxxx"]])),
I've tried:
OneMonthAgo = Text.Replace(Text.Start (Text.From(Date.AddDays(DateTime.LocalNow(),-30)),10),"/","-") & "T00:00:00.000Z",
And calling this as a variable but because the string does not come with quotation marks it gives a syntax error when the variable is called in the 'Source = ' line.
Well, first you want
= Date.ToText(Date.From(Date.AddDays(DateTime.LocalNow(),-30)), [Format="yyyy-MM-dd"])& "T00:00:00.000Z"
since that returns 2022-09-28T00:00:00.000Z while yours returns 9-28-2022 T00:00:00.000Z which does not seem to be the original format
then try out this, which I cant test
let variable = Date.ToText(Date.From(Date.AddDays(DateTime.LocalNow(),-30)), [Format="yyyy-MM-dd"])& "T00:00:00.000Z",
Source = Json.Document(Web.Contents("https://api.crewhu.com/api" & "/v1/survey?query={""_updated_at"":{""$gte"":"""&variable&"""}}", [Headers=[X_CREWHU_APITOKEN="xxxxxxxxxxx"]]))

I had the task to code the following:
Take a list of integers and returns the value of these numbers added up, but only if they are odd.
Example input: [1,5,3,2]
Output: 9
I did the code below and it worked perfectly.
numbers = [1,5,3,2]
print(numbers)
add_up_the_odds = []
for number in numbers:
if number % 2 == 1:
add_up_the_odds.append(number)
print(add_up_the_odds)
print(sum(add_up_the_odds))
Then I tried to re-code it using function definition / return:
def add_up_the_odds(numbers):
odds = []
for number in range(1,len(numbers)):
if number % 2 == 1:
odds.append(number)
return odds
numbers = [1,5,3,2]
print (sum(odds))
But I couldn’t make it working, anybody can help with that?
Note: I'm going to assume Python 3.x
It looks like you're defining your function, but never calling it.
When the interpreter finishes going through your function definition, the function is now there for you to use - but it never actually executes until you tell it to.
Between the last two lines in your code, you need to call add_up_the_odds() on your numbers array, and assign the result to the odds variable.
i.e. odds = add_up_the_odds(numbers)
I want to calculate test statistics for a fb prophet forecast in a function because I want to average the test stats over different forecasts and cutoff points after using the fb-prophet cross_validation to get df_cv. I created a function that I apply to the dataframe after grouping by the cutoff points, in order to receive a measure per cutoff point. Then I calculate the mean over all these values.
The problem is that my function returns not only the value I am looking for but also a 0 as well as an information of the dtype. I can still do calculations with the returned value but when I want to plot etc. later it is very inconvenient. How can I strip these unnecessary values from the output?
def compute_avg_stats(df_cv,perf_measure):
measures = {'mse':mean_squared_error,'mae':mean_absolute_error,'mape':mean_absolute_percentage_error,'rmse':mean_squared_error}
performance_stats = {}
if perf_measure == 'rmse':
measure = np.sqrt(measures[perf_measure](y_true=df_cv['y'],y_pred=df_cv['yhat']))
else:
measure = measures[perf_measure](y_true=df_cv['yu'],y_pred=df_cv['yhat'])
return measure
df_cv.groupby('cutoff').apply(compute_avg_stats,perf_measure='rmse').to_frame().mean()
I think .mean() returns a Series. Try with .mean()[0]
I'm trying to create a spline chart using this CSV:
slave_id,date,time,rtc_temp,temp1,temp2,temp3
1,2017/12/26,16:42:59,21,11.50,13.13,5.88
2,2017/12/26,16:43:29,21,14.13,20.63,99.99
1,2017/12/26,16:44:00,21,11.50,13.13,5.88
2,2017/12/26,16:44:30,21,14.13,20.63,99.99
1,2017/12/26,16:45:01,21,11.50,13.13,5.88
2,2017/12/26,16:45:31,21,14.13,20.63,99.99
1,2017/12/26,16:46:02,21,11.50,13.13,5.88
2,2017/12/26,16:46:32,21,14.13,20.63,99.99
As you can see here [IMAGE], the graph is showing the date and time, but the x Axis is not accepting the date / time.
Ive tried using date.UTC, but that did not work either. Can someone point me in the right direction?

I see that date variable in your code is a string:
// all data lines start with a double quote
line = line.split(',');
date = line[1] + " " + line[2];
(...)
RTC.push([
date,
parseInt(line[3], 10)
]);
If you choose to construct the point's options as an array of two values and the first value is a string then it's treated as its name property (not x).
Explanation: https://www.highcharts.com/docs/chart-concepts/series
In that case Highcharts assigns subsequent integers as x values for all points (that's why there're values like 00:00:00.000 (1 Jan 1970), 00:00:00.001 etc.).
You need to parse your date to timestamp. You can use Date.UTC() (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC) or some other function for this.
I've managed to get it working with Date.UTC using the following code:
var yyyymmdd = line[2].split("-"); //Split the date: 2017 12 16
var hhmmss = line[3].split(":"); //Split the time: 16 11 14
var date = Date.UTC(yyyymmdd[0], yyyymmdd[1] - 1, yyyymmdd[2], hhmmss[0], hhmmss[1], hhmmss[2]); //Stitch 'em together using Date.UTC
I have a matrix that looks like:
matrix =
106168 1457100277117478
106069 1457100277417227
111159 1457100277850577
24408 1457100278150562
I need to take the first element of the second column for my further calculation. But I failed to do that!
The piece of code for that is the following:
time = matrix(:, 2(1));
format long;
disp('!time = '); disp(time);
As a result I got:
!time =
1457100277117478
1457100277417227
1457100277850577
1457100278150562
I didn't use any loop :(
I would like to get only the first value, i.e., 1457100277117478.
What did I do in a wrong way?
