kandi X-RAY | Dataquest Summary
####Solutions of dataquest.io missions in Haxe language. I want to learn more about Data Science. The tutorials are written for the Python language. Because the project I want to use this for is written in Haxe I'm trying to find out if I can use the Python compile target of Haxe to do this. The directories of the missions contain the following files. Some examples use the pyextern classes. They are not included in the git. You can get them at

I have get these object whenever I click the next or previous button, it'll display like this in my console.log
Here is what I do to get it out
console.log(dataQuestion[this.state.step]) (Step is for moving index whenever I click)
But when I add
console.log(dataQuestion[this.state.step].question_desc) to get the question_desc
out, it'll get Cannot read property 'question_desc' of undefined. I don't know what I'm doing wrong. Can someone give me some answer.
Here's my piece of code....

When the component first loaded, the dataQuestion value will be empty, so the value of
dataQuestion[this.state.step] will be undefined.
So you have to check if the value is defined or undefined by using a question mark(?).

It is expected, because output of function
Series.value_counts return number of counts. So get Series with index filled by floats and values of Series are integers.

Your logic is correct, the issue is simply that the string concatenation is broken by the mis-matched quotes. Try this:
Fairly new R user here, I'm currently working through Dataquest.io's Data Analyst in R course, specifically working on the NYC School Perception Guided Project. I am trying to write a custom function that subsets two columns into a tibble and sorts each tibble in descending order by correlation coefficients. The function subsets the intended columns no problem but it never sorts the tibbles by descending correlation coefficients. I'd really like to have each tibble sorted in descending order so I can see which correlation pairs have the highest coefficients in the top rows.
You can download the correlation data I have so far on my GitHub page.
I wrote a custom function to subset and arrange tibbles in descending order, which I then mapped to two character vectors I created, that finally generates a list of 16 tibbles:...

When using variables in a function you have to deal with non-standard evaluation (NSE) because
y_var are character values and R doesn't know that those should be treated as columns.
x_var has only one value you don't need to iterate over it in
map2, instead you can pass it as a constant argument. Try :
So I have an Array of object like this :...

Edit: Added Method 3, which might be the easiest with
.loc and then
You could take a slightly different approach (with Method #1 or Method #2 below) by taking the absolute minimum of the difference between today's date and the data, but a key thing you weren't doing was wrapping
pd.to_datetime() around the
df_EndDate in order to transform it into a
DatetimeArray so that it could be compared against your
Date column. They both have to be in the same format of
DatetimeArray in order to be compared.

let me know if this works for you!
No vulnerabilities reported
You can use Dataquest like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
