Pandas: List of maximum values of difference from previous rows in new column

Asked 2021-Jun-16 at 03:33

I want to add a new column 'BEST' to this dataframe, which contains a list of the names of the columns which meet these criteria:

Subtract from the current value in each column the value in the row that is 2 rows back
The column that has the highest result of this subtraction will be listed in 'BEST'
If more more than one column shares the same highest result, they all get listed
If all columns have the same result, they all get listed

First use shift and subtract to get the diff, then replace the maximum values with the column name and drop the others.

You can check all the types are identical or not with the help of fold expression (since C++17).

ANSWER

Answered 2021-Jun-16 at 02:16

The n2 - n1 in the case of a negative number as a result when converted to bool will yield true. So n1 turns out to be less than n2. That's why it is a bad practice to use ints in such Boolean context.

Yes, as stated in the documentation:

...comparison function object which returns true if the first argument is less than the second

But the implementation of the comparison here leads to failure. Try this and see for yourself:

Based on Matplotlib documentation here the inputs for plt.scatter() are:

x, yfloat or array-like, shape (n, ) The data positions.

But in your code what you're passing to the scatter function are two pd.DataFrame. So the first column are the names but the second columns are where the values stored:

How to Config Javascript ' script in Django?

Asked 2021-Jun-16 at 02:47

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.

Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.

I don't have idea why my javascript' script isn't working.

The configurations are the followings

Run ‘python manage.py collectstatic’ and try again.

The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.

Add the following as django documentation to your urls.py

QUESTION

What is the best practice of passing reference counted C++ objects to Lua?

Asked 2021-Jun-16 at 02:17

I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

...

ANSWER

Answered 2021-Jun-10 at 19:23

I assume you have implemented two Lua functions in C: inc_ref_count(obj) and dec_ref_count(obj)
